Eye Problems (Dry Eye, Pink Eye, Eye Strain & Vision Changes)
Dry, gritty or tired eyes, pink eye, styes, floaters and the slow vision changes of cataract, glaucoma, macular degeneration and diabetic eye disease — what helps, what is an emergency, and why regular eye exams matter.
Get emergency or same-day care — go to an eye doctor or the emergency room right away, or call 911 — for:
- Sudden vision loss, or a dark shadow or “curtain” over part of your vision, or a sudden shower of new floaters, sometimes with flashes of light. These can be signs of a retinal tear or detachment, a medical emergency; treatment right away can help protect your sight (NEI (opens in a new tab), NEI (opens in a new tab)).
- Severe eye pain with redness, a headache, nausea or vomiting, blurred vision or rainbow-like halos around lights. This can be acute angle-closure glaucoma, an emergency that can cause blindness in just a few days without treatment (NHS (opens in a new tab), NEI (opens in a new tab), NEI (opens in a new tab)).
- A chemical in the eye. Rinse first, right away: take out contact lenses and run lots of room-temperature water over the eye for at least 15 to 20 minutes — a shower works for adults and older children. Then call Poison Control at 1-800-222-1222; if symptoms are severe, go straight to the emergency room after rinsing, or call 911 (Poison Control (opens in a new tab), NHS (opens in a new tab)).
- An eye injury, or an object stuck in the eye. Don’t touch or rub the eye and don’t try to remove an object that is stuck in it or has pierced it; get help right away. Something that hits the eye at high speed — for example while using power tools or mowing the lawn — also needs emergency care (NHS (opens in a new tab), NEI (opens in a new tab)).
- A red, painful eye with light sensitivity or blurred vision that doesn’t clear when you wipe away discharge — especially if you wear contact lenses (CDC (opens in a new tab), NEI (opens in a new tab)). A red eye in a contact lens wearer could be an eye infection (NHS (opens in a new tab)), and infections related to contact lenses are the most common cause of keratitis, an inflammation of the cornea (NEI (opens in a new tab)). Take your lenses out and call your eye doctor.
- A newborn with eye discharge or puffy, red eyelids — call the doctor now (NEI (opens in a new tab), CDC (opens in a new tab)).
- Sudden double vision or trouble seeing together with other stroke signs — face drooping, arm weakness, trouble speaking, loss of balance or a sudden severe headache. Call 911 (CDC (opens in a new tab)).
Blood pressure above 180/120 that stays that high on a second check, together with a sudden change in vision or a sudden, severe headache, also needs a 911 call (NHLBI (opens in a new tab)).
How common are eye problems?
Very common. Nearly 16.4 million Americans have dry eye (NEI (opens in a new tab)), and pink eye is one of the most common eye problems in both children and adults (NEI (opens in a new tab)). About 7 million people in the U.S. have vision impairment, including 1 million with blindness, and roughly 6.8% of children under 18 have a diagnosed eye or vision condition (CDC (opens in a new tab)). An estimated 20.5 million Americans aged 40 and older have a cataract in one or both eyes, and about 4.1 million have diabetic retinopathy (CDC (opens in a new tab)).
The main eye problems
- Dry eye. Your eyes don’t make enough tears, or the tears don’t work well. It can feel scratchy, stinging or burning, and can cause light sensitivity and blurry vision. It is more likely after 50, with contact lenses, and with autoimmune conditions such as lupus or Sjögren syndrome (NEI (opens in a new tab)). Air conditioning or heating, wind, dust, smoke and some medicines can make it more likely (NHS (opens in a new tab)).
- Pink eye (conjunctivitis). Redness and swelling of the white of the eye and inner eyelid, often with itching, burning, tearing or discharge. Viruses, bacteria and allergens are the most common causes (CDC (opens in a new tab)). Viral and bacterial pink eye spread easily; allergic pink eye does not (CDC (opens in a new tab)).
- Digital eye strain. When you focus on a screen for a long time you tend to blink less, which can cause eye strain or fatigue (CDC (opens in a new tab)), and long screen time can also bring on dry eye (NEI (opens in a new tab)).
- Styes and blepharitis. A stye is a small, painful lump on the eyelid, often from bacteria infecting an eyelash follicle or eyelid gland; it usually goes away within a week (NHS (opens in a new tab)). Blepharitis makes the eyelids red, swollen, itchy and crusty, with dandruff-like flakes on the lashes; it usually doesn’t go away completely and can lead to styes (NEI (opens in a new tab)).
- Floaters. Small spots, threads or cobwebs drifting across your vision. Almost everyone gets some with age, and most don’t need treatment — but a sudden burst of new floaters can signal a retinal tear or detachment (NEI (opens in a new tab)).
- Age-related eye diseases. The leading causes of blindness and low vision in the U.S. are cataract, glaucoma, age-related macular degeneration (AMD) and diabetic retinopathy (CDC (opens in a new tab)). Each is explained in Age-related eye diseases at a glance below.
- Children’s vision problems. Amblyopia (“lazy eye”) is the most common cause of vision impairment in children (CDC (opens in a new tab)), and screening finds it early — see Eye exams by age below.
Some eye problems are linked to other conditions: allergic pink eye (see our Allergies guide), diabetic eye disease (see our Diabetes guide), eye damage from high blood pressure (see our Blood Pressure guide), herpes infections of the eye (see our Cold Sores guide), eyelids that don’t close all the way, as with Bell’s palsy, which can let the eye dry out and may need treatment to protect your sight (NHS (opens in a new tab); see our Bell’s Palsy guide) and blinking or eyelid twitching you can’t control, called blepharospasm (NEI (opens in a new tab); see our Dystonia guide). MBHA guides to headaches, migraines, thyroid problems (including Graves’ disease) and Sjögren’s syndrome are on the way.
Why regular eye exams matter
Many eye diseases have no symptoms or warning signs at first. A comprehensive dilated eye exam — drops widen the pupil so the doctor can see inside the eye — is the only way to find many of them early, when they are easier to treat (NEI (opens in a new tab)). Half of people with glaucoma don’t know they have it (NEI (opens in a new tab)). An estimated 93 million U.S. adults are at high risk for serious vision loss, yet only half saw an eye doctor in the past 12 months, and 90% of blindness caused by diabetes is preventable (CDC (opens in a new tab)).
Side by side
Six approaches compared
For every condition we look at the same six approaches: what each involves, what it typically costs, and what a patient can realistically expect.
| Approach | What it involves | Estimated cost | What to expect |
|---|---|---|---|
| Conventional medicine (AMA) | Treat the cause: artificial tears and prescription drops for dry eye; antibiotic drops only for bacterial pink eye and antihistamine drops for allergic; warm compresses and lid cleaning for styes and blepharitis; cataract surgery; glaucoma drops, laser or surgery; AREDS2 supplements for intermediate or late AMD and eye injections for wet AMD; yearly diabetic eye exams; glasses and contacts. | Medicare Part B covers yearly diabetic eye exams, yearly glaucoma screening for people at high risk, cataract surgery and AMD treatment (usually 20% after the deductible); it doesn’t cover routine exams for glasses. Cash prices: cost estimate being researched. | Strong evidence. Most pink eye and styes clear on their own; about 9 in 10 people see better after cataract surgery; glaucoma and diabetic eye disease treatment can stop further vision loss but can’t undo damage. |
| Chiropractic | No role in treating eye disease. | About $90–$200 for a first visit and $55–$100 for follow-ups without insurance; not recommended for eye problems. | We found no good evidence that chiropractic treats dry eye, pink eye, glaucoma or other eye diseases. Neck manipulation is linked to rare artery tears that can lead to stroke. |
| Acupuncture | Fine needles, often at points around the eyes, mainly studied for dry eye. | About $125–$230 for a first visit and $90–$185 for follow-ups; community clinics about $50–$90. | For dry eye, many small trials report better tear tests, but most are of low quality and symptom results are mixed. Little or no reliable evidence for glaucoma or AMD. Needling near the eye has rarely caused serious eye injury. |
| Herbal medicine | AREDS2 supplements only for intermediate or late AMD; omega-3s and bilberry are promoted for eyes, but the evidence is weak or uncertain. Never put homemade or herbal preparations in the eye. | Cost estimate being researched. | AREDS2 may slow intermediate AMD from becoming advanced; it doesn’t prevent AMD. A large trial found omega-3 no better than placebo for dry eye. Bilberry hasn’t been shown to help any condition. |
| Massage therapy | Warm compresses with gentle lid cleaning for blocked eyelid oil glands; in-office eyelid-warming devices; gentle warm massage for a baby’s blocked tear duct. | Home compresses cost little. At one national chain, a 60-minute massage is about $125–$160 for nonmembers (prices vary by location); in-office gland treatments: cost estimate being researched. | Warmth and daily lid care help control blepharitis and gland symptoms, but need to be kept up; in-office warming devices work about as well as other common treatments. We found little research on body massage for eye problems. |
| MBHA Wellness Coach | Daily eye habits: the 20-20-20 screen rule, blinking, humidity, UV-blocking sunglasses, not smoking, diabetes and blood pressure control, protective eyewear, contact lens hygiene and an exam schedule. | MBHA coaching cost estimate being researched. | These steps ease screen-related strain and dryness and lower the risk of eye injuries, infections, cataract, AMD and diabetic vision loss. |
Approach 1 of 6
Conventional medicine (AMA)
Primary care providers, optometrists and ophthalmologists (medical eye doctors) share eye care. Treatment depends on the cause, so a proper diagnosis comes first. We don’t list doses — ask your eye doctor or pharmacist.
1. Dry eye
- Artificial tears, gels and ointments, sold without a prescription, are the most common treatment for mild dry eye (NEI (opens in a new tab)).
- Prescription treatments include drops that help the eyes make more tears (cyclosporine and lifitegrast) (NEI (opens in a new tab)).
- Tear duct (punctal) plugs keep tears on the eye longer, and treating the cause — such as switching a drying medicine — may help (NEI (opens in a new tab)).
2. Pink eye
- Viral pink eye usually clears in 7 to 14 days without treatment, though it can take 2 to 3 weeks or more. Antibiotics do not help viral pink eye. Serious viral infections, such as those caused by herpes simplex virus or varicella-zoster virus (the chickenpox and shingles virus), are treated with antiviral medicine (CDC (opens in a new tab)).
- Bacterial pink eye often clears in 2 to 5 days on its own. Antibiotic drops or ointment may shorten it and are more likely to be needed with pus, a weakened immune system or certain bacteria (CDC (opens in a new tab)).
- Allergic pink eye improves when the allergen is removed. Antihistamine and other allergy eye drops, some by prescription, give relief (CDC (opens in a new tab)). See our Allergies guide.
- Cold compresses and artificial tears ease any type (CDC (opens in a new tab)). Herpes eye infections can spread into the cornea and cause scarring and vision loss, so they need an eye doctor, who can prescribe antiviral medicine (NEI (opens in a new tab)); see our Cold Sores guide.
3. Styes and blepharitis
For a stye, hold a clean cloth soaked in warm water on it for 5 to 10 minutes, 2 to 4 times a day, and never try to burst it or pull out an eyelash yourself — that can spread the infection. A provider may burst it with a thin, sterile needle, remove the nearest eyelash or refer you to an eye specialist (NHS (opens in a new tab)). Blepharitis is managed with daily lid cleaning and warm compresses; providers may add steroid eye drops, artificial tears, or antibiotic drops, ointments or pills when bacteria are the cause, and treating a related problem such as rosacea or dandruff helps (NEI (opens in a new tab)).
4. Floaters and retinal tears
Floaters from normal aging usually need no treatment (NEI (opens in a new tab)). A retinal tear or detachment is repaired with laser, freezing treatment or surgery, which is ultimately successful for about 9 out of 10 people (NEI (opens in a new tab)).
5. Cataract surgery
Early on, brighter lights, anti-glare sunglasses, magnifiers or a new glasses prescription help. When cataracts get in the way of reading, driving or other daily activities, surgery replaces the cloudy lens with an artificial one. It is very safe, and 9 out of 10 people see better afterward; waiting usually won’t harm your eyes (NEI (opens in a new tab)).
6. Glaucoma: drops, laser and surgery
Prescription eye drops that lower eye pressure are the most common treatment; laser treatment in the office and surgery help fluid drain when drops aren’t enough. Treatment can stop damage from getting worse but can’t undo it, so take drops every day as prescribed (NEI (opens in a new tab)). An acute angle-closure attack is treated as an emergency with laser treatment and medicine to help the fluid drain, and doctors may treat both eyes to prevent future problems (NEI (opens in a new tab)).
7. Age-related macular degeneration (AMD)
- There is no treatment for early AMD; your eye doctor tracks it with regular exams (NEI (opens in a new tab)).
- AREDS2 supplements: in clinical trials, the AREDS and AREDS2 vitamin and mineral formulas benefited people with intermediate or late AMD. There was no benefit for people with early AMD or without AMD (NEI (opens in a new tab)). See the herbal section below.
- Wet AMD: anti-VEGF medicines injected into the eye, and photodynamic therapy (injections plus laser), may stop further vision loss. There is currently no treatment for late dry AMD, but low-vision devices and vision rehabilitation help (NEI (opens in a new tab)).
8. Diabetic eye disease
People with diabetes need a comprehensive dilated eye exam at least once a year. Anti-VEGF injections, corticosteroids, laser treatment and vitrectomy can stop diabetic retinopathy from getting worse, alongside control of blood sugar, blood pressure and cholesterol (NEI (opens in a new tab)). Uncontrolled high blood pressure can also damage the eyes (NHLBI (opens in a new tab)). See our Diabetes and Blood Pressure guides.
9. Glasses and contact lenses
Nearsightedness, farsightedness, astigmatism and the loss of close focus after 40 are the most common eye problems in the U.S. and are corrected with glasses, contacts or sometimes surgery (CDC (opens in a new tab)). Contacts are medical devices, and poor lens care raises the risk of serious eye infections (CDC (opens in a new tab)).
What it costs
- Diabetic eye exams: Medicare Part B covers one a year if you have diabetes; you pay 20% of the Medicare-approved amount after the deductible (Medicare.gov (opens in a new tab)).
- Glaucoma screening: covered once every 12 months for people at high risk — those with diabetes or a family history of glaucoma, African Americans 50 and older, and Hispanic people 65 and older; 20% after the deductible (Medicare.gov (opens in a new tab)).
- Cataract surgery: Part B may cover surgery with a conventional lens (20% after the deductible), plus one pair of glasses with standard frames or one set of contacts afterward (Medicare.gov (opens in a new tab)).
- AMD: Part B may cover certain tests and treatments, including injected drugs (Medicare.gov (opens in a new tab)).
- Routine exams for glasses or contacts are not covered by Original Medicare; some Medicare Advantage plans add vision benefits (Medicare.gov (opens in a new tab)).
- Cash prices for eye exams, drops and surgery: MBHA cost estimate being researched.
How well it works — what to expect
Dry eye is common and not usually serious (NHS (opens in a new tab)), though severe untreated dry eye can sometimes damage the cornea (NEI (opens in a new tab)), and styes are rarely a sign of anything serious and usually go away within a week (NHS (opens in a new tab)). For the serious diseases, early detection counts most: early treatment can prevent or delay blindness from diabetic retinopathy in 90% of people with diabetes (CDC (opens in a new tab)).
Approach 2 of 6
Chiropractic
Chiropractic is a licensed health profession that usually involves hands-on therapy, often spinal manipulation (NCCIH (opens in a new tab)). We found no good evidence that chiropractic care treats dry eye, pink eye, styes, glaucoma, cataracts, macular degeneration or diabetic eye disease, and none of the national eye-health sources we reviewed lists it as a treatment. It has no role in eye care.
A caution about neck manipulation. Manipulation of the neck has been linked to small but potentially dangerous tears in the neck arteries (cervical artery dissection). These are rare and there is disagreement about whether manipulation causes them, but they can lead to a stroke, and patients should be told about this risk (NCCIH (opens in a new tab)). Sudden trouble seeing is one of the warning signs of stroke — call 911 (CDC (opens in a new tab)).
What it costs
About $90–$200 for a first visit and $55–$100 for follow-ups without insurance (The Pricer (opens in a new tab)) — but we don’t recommend it for eye problems.
Approach 3 of 6
Acupuncture
Acupuncture for eye problems has mostly been studied for dry eye. Many trials exist, but their quality is a real concern.
Dry eye: what the research says
- 2011 systematic review: 6 trials. The authors found limited evidence, and said the number of trials, their size and their quality were too low to draw firm conclusions (systematic review, Acta Ophthalmol (opens in a new tab)).
- 2021 meta-analysis: 21 trials (1,542 eyes). Acupuncture did better than artificial tears alone on tear tests and symptom scores (meta-analysis, Acta Ophthalmol (opens in a new tab)).
- 2022 systematic review: 394 patients. Acupuncture improved tear tests and a dry-eye symptom questionnaire, and no severe side effects were seen (systematic review, Front Med (opens in a new tab)).
- 2024 meta-analysis: 16 trials (1,383 patients). Adding acupuncture to artificial tears improved tear tests, but there was no significant difference on the main dry-eye symptom questionnaire (meta-analysis, Medicine (opens in a new tab)).
- 2026 evidence map: 319 randomized trials of acupuncture and moxibustion for dry eye; their methods were generally of low quality, and the authors call for better-designed trials (evidence map, Front Med (opens in a new tab)).
In short: acupuncture may improve some tear measurements in dry eye, but the evidence is low-quality and its effect on how your eyes actually feel is uncertain. We did not find a Cochrane review on acupuncture for dry eye.
Other eye diseases
A 2020 Cochrane review found only three small trials for glaucoma, all at high risk of bias, and concluded it is impossible to draw reliable conclusions supporting acupuncture for glaucoma (Cochrane review, 2020 (opens in a new tab)). A 2023 review of 9 trials in AMD found no high-quality evidence that acupuncture works (systematic review, PLoS One (opens in a new tab)). Acupuncture never replaces glaucoma drops, AMD injections or diabetic eye care.
Safety
Relatively few complications from acupuncture have been reported, but problems have come from non-sterile needles and poor technique (NCCIH (opens in a new tab)). Needling close to the eye carries its own risk: a 2023 review collected 14 published cases of serious eye injury from acupuncture around the eye (case review, Korean J Ophthalmol (opens in a new tab)). Choose a licensed practitioner and tell your eye doctor.
What it costs
Private sessions run about $125–$230 for a first visit and $90–$185 for follow-ups; community clinics about $50–$90 a visit (The Pricer (opens in a new tab)).
Approach 4 of 6
Herbal medicine
Never put homemade or herbal preparations in your eye. Eye drops must be sterile to be safe, and drugs applied to the eyes bypass some of the body’s natural defenses (FDA (opens in a new tab), FDA (opens in a new tab)). The FDA has warned about unapproved eye drops that were contaminated with bacteria and fungi and could cause vision-threatening infections (FDA (opens in a new tab)). Contact lenses need the same care: poor lens hygiene raises the risk of Acanthamoeba keratitis, a serious eye infection that can lead to permanent vision loss (CDC (opens in a new tab)).
AREDS2: a specific formula, not just any eye vitamin
The AREDS and AREDS2 trials, funded by the National Eye Institute, tested specific high-dose combinations of vitamins C and E, zinc, copper and either beta-carotene (AREDS) or lutein and zeaxanthin (AREDS2). Key points from NEI (NEI (opens in a new tab)):
- They benefited people with intermediate or late AMD only — not people with early AMD or no AMD. Supplements cannot prevent AMD, but may delay progression to advanced AMD.
- A daily multivitamin can’t substitute: the trial doses were much higher, and diet alone can’t easily reach them.
- The original formula’s beta-carotene was linked to more lung cancer in former smokers, while lutein and zeaxanthin protected as well or better, so the AREDS2 formula uses them instead. People who got little lutein and zeaxanthin from their diet benefited most.
- Vitamin E can interact with blood thinners and other medicines, so talk to your doctor before starting.
We don’t list the formula’s amounts — ask your eye doctor whether it is right for you and which product matches the tested formula.
Omega-3 (fish oil) for dry eye
Omega-3 (fish oil) supplements are often suggested for dry eye, and several small studies suggested they might help (NCCIH (opens in a new tab)). But the NIH-funded DREAM trial gave 535 people with moderate-to-severe dry eye omega-3s or an olive oil placebo for a year and found no significant benefit over placebo on symptoms or eye-surface tests (DREAM trial, NEJM 2018 (opens in a new tab)). A 2019 Cochrane review of 34 trials called the evidence uncertain and inconsistent (Cochrane review, 2019 (opens in a new tab)), and NCCIH summarizes both (NCCIH (opens in a new tab)). Adding omega-3s to the AREDS formula gave no extra benefit for AMD (NCCIH (opens in a new tab)).
Bilberry
Bilberry is promoted for eye conditions, but it hasn’t been clearly shown to help any health condition, and the most rigorous studies found it doesn’t improve night vision in healthy people. The fruit is safe in food amounts; check with your provider if you take medicines (NCCIH (opens in a new tab)).
Eye drop recalls and copycat products
In 2023 the FDA told consumers to stop using more than two dozen over-the-counter eye drops sold under several store brands after finding unsanitary conditions and bacteria at the factory (FDA (opens in a new tab)). In 2024 it warned about contaminated copycat drops sold online and advised buying eye products only from reputable retailers such as state-licensed pharmacies (FDA (opens in a new tab)). Signs of an eye infection after using drops need medical care right away (FDA (opens in a new tab)).
Tea tree oil has been studied on the eyelids for blepharitis caused by Demodex (eyelash) mites, but its effectiveness is uncertain, and tea tree oil should never be swallowed (NCCIH (opens in a new tab)), so use it only on your provider’s advice. Cost of supplements: cost estimate being researched.
Approach 5 of 6
Massage therapy
Massage in eye care means gentle warmth and lid care, not body massage.
Warm compresses and lid care for blocked eyelid glands
- Clogged or irritated eyelid oil glands (meibomian glands) are one cause of blepharitis. The main treatment is cleaning the lids every day; a warm compress loosens crusts and can help keep the glands from clogging. Blepharitis usually doesn’t go away completely, so lid care needs to be kept up (NEI (opens in a new tab)).
- For blepharitis: twice a day, hold a cloth or cotton wool soaked in warm water on the closed eyelid for 5 to 10 minutes, gently massage the lids for about 30 seconds, then wipe along the lid edges with cotton wool or a cotton swab — a little baby shampoo in the water may help (NHS (opens in a new tab)).
- An eye doctor may offer an in-office device that warms and presses the eyelids (thermal pulsation, such as LipiFlow). A 2024 Cochrane review of 13 trials found it worked about as well as other common dry eye treatments, including basic warm compresses, but the evidence was of low or very low certainty (Cochrane review, 2024 (opens in a new tab)).
Babies with a blocked tear duct
For a newborn whose watery eye comes from a blocked tear duct, gentle, warm massage between the eye and the side of the nose may help; surgery may be needed if it hasn’t cleared by age 1 (CDC (opens in a new tab), NEI (opens in a new tab)). Have the baby seen first — newborn eye discharge can be a serious infection.
Body massage
We found little research on massage for eye problems. Its risk appears low (NCCIH (opens in a new tab)), but never touch or rub an injured eye (NHS (opens in a new tab)).
What it costs
Warm compresses at home cost little. At one national chain, Massage Envy, a 60-minute massage was listed at about $125–$160 for nonmembers at three locations; prices vary by location (The Pricer (opens in a new tab)). In-office gland treatments: cost estimate being researched.
Approach 6 of 6
MBHA Wellness Coach
Many eye problems can be eased or prevented with daily habits. An MBHA Wellness Coach can help you build them — always alongside your eye care.
Screens: the 20-20-20 rule and blinking
Every 20 minutes, look at something about 20 feet away for 20 seconds (CDC (opens in a new tab), NEI (opens in a new tab)). More screen habits are in Dry eye and screen strain: daily habits below.
Sun and injury protection
- Wear sunglasses that block 99 to 100% of UVA and UVB rays, even on cloudy days (NEI (opens in a new tab), CDC (opens in a new tab)), plus a brimmed hat to help protect against cataracts (NEI (opens in a new tab)).
- Wear safety glasses, goggles or sport eye guards for sports, power tools, chemicals and home repairs. About 2,000 U.S. workers have job-related eye injuries needing treatment every day, and the right eye protection can prevent 90% of them or make them less severe (CDC (opens in a new tab), CDC (opens in a new tab)).
Not smoking
Smoking raises the risk of macular degeneration and cataracts and can damage the optic nerve (NEI (opens in a new tab), CDC (opens in a new tab)); quitting is also one of the steps that may lower AMD risk (NEI (opens in a new tab)). Free help: 1-800-QUIT-NOW (1-800-784-8669) (NEI (opens in a new tab)). Smoking and smoky places also make dry eye more likely (NHS (opens in a new tab)).
Diabetes, blood pressure and everyday health
Keeping blood sugar, blood pressure and cholesterol in range lowers the risk of diabetic retinopathy (NEI (opens in a new tab), CDC (opens in a new tab)). Regular activity, a healthy weight, leafy greens and fish are good for the eyes too (NEI (opens in a new tab), NEI (opens in a new tab)). See our Diabetes and Blood Pressure guides.
Contact lens hygiene
- Don’t sleep in lenses unless your eye care provider tells you to, and take them out before swimming or showering (CDC (opens in a new tab)). Wearing lenses while swimming, using a hot tub or showering may raise the risk of Acanthamoeba keratitis, a serious eye infection (CDC (opens in a new tab)).
- Wash and dry your hands before touching lenses; rub and rinse them with fresh disinfecting solution, never water, and never top up old solution (CDC (opens in a new tab)).
- Clean the case, store it upside down with the caps off, and replace it at least every three months. Carry backup glasses, see your eye care provider yearly, and take lenses out and call if your eyes are uncomfortable (CDC (opens in a new tab)).
Keeping up with eye exams
Know your family’s eye history and keep to an exam schedule (CDC (opens in a new tab)). A coach can help you book exams and make a reminder plan — see Eye exams by age below. MBHA coaching cost estimate being researched.
Another approach
Dry eye and screen strain: daily habits
Dry eye is common and not usually serious (NHS (opens in a new tab)), and small daily changes make a real difference.
- Take screen breaks. Limit screen time, take breaks from staring at screens (NEI (opens in a new tab)) and use the 20-20-20 rule (CDC (opens in a new tab)).
- Blink. When you focus on a screen or one thing for a long time you can forget to blink, which can cause eye strain or fatigue (CDC (opens in a new tab)).
- Add moisture. Use a humidifier, and avoid smoke, wind and air conditioning (NEI (opens in a new tab)); limit time in air-conditioned or heated rooms and in smoky, dry or dusty places (NHS (opens in a new tab)). Wraparound sunglasses help outdoors (NEI (opens in a new tab)).
- Check your medicines. Some medicines, such as certain antidepressants or blood pressure medicines, can make dry eye more likely; don’t stop a prescribed medicine on your own (NHS (opens in a new tab)) — your doctor may suggest a different one (NEI (opens in a new tab)).
- Rest and fluids. NEI suggests drinking plenty of water and getting about 7 to 8 hours of sleep (NEI (opens in a new tab)).
- Keep lids clean. Clean your eyelids every day; a warm (not hot) wet cloth pressed gently on the lids makes the oil from the eyelid glands flow more easily (NHS (opens in a new tab)).
- Children: limit screen time, encourage frequent breaks and outdoor play, and get your child’s vision checked if they squint, rub their eyes or get headaches after schoolwork (CDC (opens in a new tab)).
When dry eye needs a doctor
See your eye doctor or primary care provider if your eyes are still dry after a few weeks of home care or the shape of your eyelids changes. Get an urgent appointment if your eye is painful and red, or if you have a red eye and wear contact lenses — it could be an infection. Get emergency care for any change in your sight, such as wavy lines, flashes or loss of vision; if it hurts to look at light; if you have a red eye with a severe headache and feel sick; or after an eye injury (NHS (opens in a new tab)). Untreated severe dry eye can sometimes damage the cornea (NEI (opens in a new tab)).
Another approach
Pink eye: when it’s contagious
Viral and bacterial pink eye are very contagious; allergic pink eye and pink eye from irritants such as smoke or chemicals are not (CDC (opens in a new tab)). Infections spread through close contact, droplets from coughs and sneezes, and touching germy hands or objects and then your eyes (CDC (opens in a new tab)). It can be hard to tell the types apart because the symptoms are often the same (NEI (opens in a new tab)).
Stop the spread
- Wash your hands often with soap and water for at least 20 seconds, especially before and after touching your eyes or putting in drops (CDC (opens in a new tab)).
- Don’t share pillows, towels, washcloths, eye drops, makeup, makeup brushes, contact lenses, lens cases or glasses, and wash bedding and towels in hot water (CDC (opens in a new tab)).
- Wipe discharge with a clean, wet washcloth or a fresh cotton ball each time; don’t use the same drop bottle for an infected and an uninfected eye; and stay out of swimming pools (CDC (opens in a new tab)).
- Afterward, throw away eye makeup, disposable lenses, lens solution and cases used while you were infected (NEI (opens in a new tab)).
- Vaccines against measles, rubella, chickenpox, shingles, pneumococcus and Hib protect against some infections connected to pink eye (CDC (opens in a new tab)).
Back to school or work
If you have no fever or other symptoms, you may be allowed to return with your doctor’s approval. Stay home if you still have symptoms and your school or work involves close contact with others (CDC (opens in a new tab)). Pink eye often gets better on its own in 7 to 10 days (NEI (opens in a new tab)).
See a provider for eye pain, light sensitivity, blurred vision, intense redness or symptoms that get worse (CDC (opens in a new tab)), and see the emergency box at the top of this page.
Another approach
Eye exams by age
Babies and young children
The U.S. Preventive Services Task Force recommends vision screening at least once between ages 3 and 5 to find amblyopia (“lazy eye”) or its risk factors, such as crossed eyes or a large difference in focus between the eyes. Treatment includes glasses, eye patching or atropine eye drops. Evidence is not yet enough to judge routine screening before age 3 (2017 recommendation; an update is in progress) (USPSTF (opens in a new tab)). Amblyopia affects 2 to 3 of every 100 children, yet fewer than half of preschoolers have had their vision tested (CDC (opens in a new tab)).
Adults
How often you need a comprehensive dilated eye exam depends on your risk for eye disease, so ask your eye doctor what’s right for you (NEI (opens in a new tab)). The UK’s National Health Service advises everyone to have an eye test at least every 2 years (NHS (opens in a new tab)).
People at higher risk
- Diabetes: a dilated eye exam at least once a year (NEI (opens in a new tab)). Most people with diabetes or high blood pressure need one at least yearly (NEI (opens in a new tab)).
- Every 1 to 2 years if you are over 60, African American and over 40, or have a family history of glaucoma (NEI (opens in a new tab)).
Don’t wait for your next exam if you notice
decreased or double vision, eye pain, redness or discharge, new floaters, flashes of light or halos around lights (CDC (opens in a new tab)). For sudden symptoms, see the emergency box at the top of this page.
