Your vision changes as you age, and regular eye care becomes more important
Your eyes change significantly after 60. The lens becomes less flexible, making it harder to focus on close objects. The pupil shrinks, so you need more light to see clearly. The retina becomes more sensitive to glare. These changes are normal, but they mean you need different care than you did at 40 — and you need to catch problems like glaucoma, macular degeneration, and cataracts early, when treatment works best.
Regular eye exams are the foundation. A comprehensive exam (not just a vision screening) can detect diseases you have no symptoms for yet. Medicare covers one exam every 24 months for most seniors, and more often if you have diabetes or glaucoma. If you have a supplemental plan or Medicare Advantage, your coverage may be broader. The key is scheduling the right type of exam and knowing what to expect.
Key Takeaways
- Medicare covers one comprehensive eye exam every 24 months, and more frequently if you have diabetes, glaucoma, or age-related macular degeneration.
- An optometrist can perform routine exams and prescribe glasses and contacts; an ophthalmologist is a medical doctor who can also perform surgery and treat eye disease.
- Common age-related eye conditions — cataracts, glaucoma, macular degeneration, and diabetic retinopathy — often have no early symptoms, so regular testing is the only way to catch them.
- You will pay 20 percent of the Medicare-approved amount for a comprehensive exam after you meet your Part B deductible, and nothing for the exam itself if you see a provider who accepts Medicare assignment.
What happens during a comprehensive eye exam
A comprehensive exam is different from a simple vision test. The provider will check your visual acuity (how clearly you see at different distances), test your eye pressure, examine the back of your eye with dilating drops, and assess how well your eyes work together. The whole appointment usually takes 45 minutes to an hour. Bring your current glasses or contacts, a list of medications you take, and your insurance card.
Dilating drops are standard in a comprehensive exam. They make your pupils larger so the provider can see the retina and optic nerve clearly. Your vision will be blurry and you will be sensitive to light for a few hours afterward — plan to have someone drive you, or take a taxi or rideshare home. Do not drive yourself immediately after dilation. If you have narrow angles or a history of angle-closure glaucoma, tell the provider before they use dilating drops, because in rare cases they can trigger an acute attack.
The provider will discuss what they found and whether you need treatment, glasses, or follow-up testing. If they suspect glaucoma, they may order a visual field test or optical coherence tomography (OCT) scan to get more detail. If they find a cataract, they will tell you when it is affecting your vision enough to consider surgery. If they detect macular degeneration or diabetic retinopathy, they will explain your options and how often you need to return.
The difference between an optometrist and an ophthalmologist
An optometrist has a Doctor of Optometry degree (O.D.) and can perform eye exams, prescribe glasses and contact lenses, and diagnose common eye conditions. They cannot perform surgery or prescribe certain medications in most states. An ophthalmologist is a medical doctor (M.D. or D.O.) who can do everything an optometrist does, plus perform eye surgery and manage complex eye diseases. Both are covered by Medicare for routine exams.
For routine care and glasses, either provider works. If you have glaucoma, macular degeneration, or diabetic retinopathy, an ophthalmologist is often the better choice because they can manage the condition over time and perform procedures if needed. Some seniors see an optometrist for routine exams and glasses, then see an ophthalmologist if a problem is found. Ask your primary care doctor for a referral if you are not sure where to start.
Common eye conditions in seniors and what to watch for
Cataracts are clouding of the lens. They develop slowly and often have no symptoms at first. You might notice blurred or dim vision, difficulty seeing at night, or colors looking faded. Cataracts are extremely common — most people over 80 have at least one. Surgery is very effective and is usually done when the cataract interferes with your daily life, not on a schedule. Medicare covers cataract surgery if your provider documents that it is medically necessary.
Glaucoma is increased pressure inside the eye that damages the optic nerve. It usually has no early symptoms, which is why regular testing is critical. Over time, you lose peripheral vision first, then central vision. Once vision is lost to glaucoma, it cannot be restored, but medication or surgery can slow or stop further damage. Medicare covers glaucoma testing and treatment.
Age-related macular degeneration (AMD) affects the macula, the part of the retina responsible for sharp central vision. Dry AMD is more common and progresses slowly; wet AMD progresses faster and can cause more vision loss. Early signs include straight lines appearing wavy, or a blurry spot in the center of your vision. There is no cure, but certain vitamins, laser treatment, or injections can slow progression in some people. Early detection matters.
Diabetic retinopathy occurs when high blood sugar damages blood vessels in the retina. It often has no symptoms until significant damage has occurred. If you have diabetes, you need an eye exam at least once a year, and more often if your provider recommends it. Medicare covers these exams and any treatment needed.
How Medicare covers eye care
Medicare Part B covers one comprehensive eye exam every 24 months for beneficiaries without diabetes or glaucoma. If you have diabetes or glaucoma, you are covered for more frequent exams — usually once a year, though your provider can request more often if medically necessary. After you meet your Part B deductible, you pay 20 percent of the Medicare-approved amount. If your provider accepts Medicare assignment, they bill Medicare directly and you pay only your 20 percent share.
Medicare does not cover routine glasses or contact lenses, but it does cover one pair of glasses or contact lenses after cataract surgery. If you need glasses for other reasons, you pay out of pocket. Many supplemental (Medigap) plans cover routine eye exams and glasses; check your plan documents or call the plan to confirm. Medicare Advantage plans vary widely — some cover routine exams and glasses, others do not. Review your plan's coverage before your appointment.
If you cannot afford glasses or contacts, some community health centers and nonprofit organizations offer low-cost or free eyewear. Your eye care provider can refer you, or you can search for programs through your local health department or a 211 call.
Managing dry eyes and other common discomforts
Dry eyes are extremely common in seniors, especially if you take medications like antihistamines, blood pressure drugs, or antidepressants. Symptoms include grittiness, burning, or paradoxically, excessive tearing (because irritation triggers reflex tearing). Over-the-counter artificial tears work for mild cases. If symptoms are persistent, your eye care provider can recommend prescription drops, punctal plugs (tiny devices that block tear drainage to keep tears on the eye longer), or other treatments.
Presbyopia — difficulty focusing on close objects — is universal after 60. Reading glasses, bifocals, or progressive lenses can correct it. If you have presbyopia and also need distance correction, progressive lenses (which blend multiple prescriptions) are more convenient than bifocals, though they take a few days to adjust to. Your optometrist can help you choose the best option for your lifestyle.
Floaters (small spots or lines that drift across your vision) and occasional flashes of light are usually harmless and become more common with age. However, a sudden increase in floaters, a shower of floaters, or flashes accompanied by vision loss can signal retinal detachment, which is an emergency. Call your eye care provider or go to an emergency room immediately if this happens.
Protecting your vision as you age
UV exposure increases the risk of cataracts and macular degeneration. Wear sunglasses that block 100 percent of UVA and UVB rays whenever you are outside, even on cloudy days. A wide-brimmed hat adds extra protection. If you spend a lot of time outdoors, consider photochromic lenses (glasses that darken in sunlight).
Nutrition matters. Antioxidants and minerals like lutein, zeaxanthin, zinc, and vitamins C and E may slow macular degeneration. These are found in leafy greens, orange and yellow vegetables, nuts, and fish. If you have macular degeneration, your eye care provider may recommend a specific vitamin formula; the AREDS2 study identified a combination that slows progression in some people.
If you have diabetes, keeping your blood sugar, blood pressure, and cholesterol controlled reduces your risk of diabetic retinopathy and other eye problems. Work with your primary care doctor on these targets. If you smoke, quitting reduces your risk of macular degeneration and cataracts significantly — it is never too late to benefit.
Finding an eye care provider and scheduling your first exam
Start by asking your primary care doctor for a referral. If you do not have a primary care doctor, call your local health department or search Medicare's provider directory at Medicare.gov. You can filter by location and whether the provider accepts Medicare assignment. Call ahead to confirm they are accepting new patients and to ask about wait times — some providers have a several-month backlog.
If cost is a concern, community health centers often offer eye exams on a sliding fee scale based on income. Call 211 or search 211.org to find centers near you. Some nonprofit organizations also provide free or low-cost eye exams and glasses to seniors with limited income; your local Area Agency on Aging can point you to programs in your area.
Schedule your exam during a time when you can arrange transportation if needed (especially if dilation is planned). Bring your insurance card, a list of current medications, and your glasses or contacts. If you have had eye problems in the past, bring any records or test results from previous exams.
Frequently Asked Questions
How often should I have my eyes checked if I do not have diabetes or glaucoma?
Medicare covers one comprehensive exam every 24 months. However, many eye care providers recommend annual exams for seniors, especially if you have risk factors like high blood pressure, high cholesterol, or a family history of eye disease. Ask your provider what schedule makes sense for you.
What should I do if I cannot afford glasses after my exam?
Community health centers, nonprofit organizations, and some Lions Clubs offer low-cost or free eyewear to seniors with limited income. Your eye care provider can refer you, or call 211 to find programs in your area. Some online retailers also offer affordable frames and lenses if you have a current prescription.
Can I get an eye exam if I do not have Medicare?
Yes. Community health centers offer exams on a sliding fee scale. If you have a private insurance plan, check your coverage. If you are uninsured, call your local health department or 211 to find low-cost or free exam options in your area.
What is the difference between a vision screening and a comprehensive eye exam?
A vision screening checks how clearly you see and may test eye pressure. A comprehensive exam includes those tests plus dilation, detailed examination of the retina and optic nerve, and assessment of eye health. Screenings can miss early glaucoma, macular degeneration, and other diseases. Medicare covers comprehensive exams, not screenings.
Is it normal to need new glasses every year?
Your prescription can change as your eyes age, especially in your 60s and 70s. Annual or biennial exams help catch these changes. However, if your prescription changes very frequently or dramatically, tell your eye care provider — it can sometimes signal an underlying condition like diabetes or cataracts that needs attention.
