How to Care for Your Eyes as You Age

The most common age-related eye diseases — macular degeneration, glaucoma, cataracts, and diabetic retinopathy — can silently rob vision before symptoms appear. Regular dilated eye exams are the only way to detect many of them early. UV-blocking sunglasses, not smoking, and controlling blood pressure and blood sugar also reduce risk significantly.

What normal vision changes come with aging?

Not every vision change with age signals disease. Several changes are nearly universal and are the result of normal physiology:

  • Presbyopia — the gradual loss of near-focus ability, typically beginning in the early forties. The crystalline lens loses flexibility, making it harder to shift focus from distance to near. Reading glasses or progressive lenses address this 1.
  • Reduced contrast sensitivity — colors and edges may appear slightly less distinct in low light, which is why older adults sometimes need more light to read comfortably.
  • Slower dark adaptation — adjusting from bright light to a dark room takes longer.
  • Dry eye — tear production tends to decrease with age, and the composition of tears changes. Dry eye is more common in women, especially after menopause 2.
  • Increased glare sensitivity — light scattering inside the eye increases with early lens changes.
  • Floaters — the vitreous (the gel filling the eye) becomes more liquid with age, and fibrous clumps create floating specks or strings. Occasional stable floaters are benign; a sudden increase is a warning sign.

Which age-related eye diseases should you screen for?

These four conditions account for most preventable vision loss in older adults in the United States:

1. Glaucoma Glaucoma is often called the "silent thief of sight" because it destroys peripheral vision gradually and painlessly. By the time someone notices central vision loss, significant permanent damage may have occurred. Risk increases substantially after age 60 and in people with a family history, African American ancestry, or elevated intraocular pressure. Early detection through regular dilated exams and IOP measurement is the only proven way to prevent blindness from glaucoma [3, 4].

2. Age-Related Macular Degeneration (AMD) AMD affects the central retina (the macula) and is the leading cause of severe vision loss in people over 65 in developed countries. Dry AMD progresses slowly; wet AMD can progress rapidly but is treatable with regular injections into the eye (anti-VEGF therapy) when caught early. Risk factors include smoking, family history, and prolonged UV exposure [5, 6].

3. Cataracts The eye's lens gradually clouds with age, reducing clarity and increasing glare. Most people over 80 have some degree of cataract. When cataracts significantly impair function, surgical removal and replacement with an artificial intraocular lens is highly effective 7.

4. Diabetic Retinopathy People with diabetes can develop damage to the blood vessels of the retina that causes progressive vision loss. Annual dilated eye exams are recommended for anyone with type 1 or type 2 diabetes — the longer the duration and the less controlled the blood sugar, the higher the risk 8.

How often should you have an eye exam as you get older?

The American Academy of Ophthalmology recommends that adults with no known eye disease or risk factors have a comprehensive dilated eye exam at least every one to two years by age 65, and that adults over 65 consider annual exams 1. If you have:

  • Diabetes → annual dilated exam from the time of diagnosis 8
  • Glaucoma or glaucoma risk factors (family history, elevated IOP, age over 60) → more frequent monitoring, per your ophthalmologist
  • A previous eye disease → as directed by your treating clinician

Many adults go years without a dilated exam. A basic vision screening (reading a wall chart) does not detect glaucoma, AMD, or diabetic retinopathy — only a dilated examination allows the retina and optic nerve to be directly viewed.

What lifestyle habits protect eye health as you age?

Do not smoke. Smoking is one of the strongest modifiable risk factors for AMD and is also associated with increased cataract risk and diabetic retinopathy progression. Quitting at any age reduces risk 6.

Wear UV-blocking sunglasses. Cumulative UV exposure damages the lens and retina over time. Sunglasses labeled "100% UV protection" or "UV400" block both UVA and UVB. Wraparound styles offer better peripheral coverage. A wide-brimmed hat adds further protection.

Control your blood pressure and blood sugar. Hypertension and diabetes are both major drivers of retinal vascular disease. Tight control of these conditions, guided by your primary care or endocrinology team, protects the small blood vessels of the retina.

Eat a diet with leafy greens, fish, and colorful vegetables. Lutein and zeaxanthin (found in kale, spinach, and eggs) concentrate in the macula and are associated with lower AMD risk. Omega-3 fatty acids may support tear production in dry eye. Specific high-dose supplements (the AREDS2 formula — vitamins C and E, lutein/zeaxanthin, zinc, and copper) are recommended by ophthalmologists for people with intermediate or advanced dry AMD to slow progression to wet AMD; this supplement is not appropriate as a general preventive for people without AMD 6.

Manage dry eye proactively. Preservative-free artificial tears, increased water intake, and addressing environmental triggers (low humidity, forced-air heating, excessive screen time) reduce chronic dryness that impairs quality of life and, if severe, can affect the ocular surface 2.

Protect eyes from trauma. Wear protective eyewear during sports, lawn care, power tool use, or any activity where projectiles or chemicals pose a risk. Eye injuries are among the most preventable causes of vision loss.

What vision warning signs should prompt a same-day call to an eye doctor?

Some symptoms need prompt attention rather than a wait-and-see approach:

  • Sudden increase in floaters or new large floaters — possible posterior vitreous detachment or retinal tear
  • Flashing lights in peripheral vision — same concern as above
  • A shadow, curtain, or missing area in your vision — possible retinal detachment
  • Sudden distortion of straight lines (e.g., a door frame appearing wavy) — possible onset of wet AMD affecting the macula
  • Sudden loss of vision in one eye — possible vascular event (retinal artery or vein occlusion)
  • Eye pain with headache, halos around lights, and nausea — possible acute angle-closure glaucoma, an emergency [3, 4]

Common questions

At what age should I start having my eyes dilated?

The American Academy of Ophthalmology recommends a comprehensive baseline eye examination for all adults by age 40, and more frequently from age 65 onward. Adults with diabetes, glaucoma risk, or a family history of eye disease should start earlier and be seen more frequently regardless of age.

Do AREDS2 vitamins prevent macular degeneration?

No — AREDS2 supplements are specifically indicated for people who already have intermediate or advanced dry AMD in one or both eyes. Clinical evidence supports that the AREDS2 formula slows progression to wet (advanced) AMD in those individuals. There is no evidence that taking these supplements prevents AMD from developing in people with healthy retinas. A general healthy diet with leafy greens and fish is appropriate for everyone; AREDS2 dosing is a clinical decision for your ophthalmologist.

Is it normal for my vision to change a lot after 60?

Some change is normal — presbyopia progresses, cataract formation often advances, and dry eye tends to worsen. Significant or rapid changes — particularly any sudden change, new distortion, or missing areas — are not normal and need prompt evaluation. Gradual, bilateral changes that are correctable with updated glasses are generally expected.

Can anything be done about cataracts besides surgery?

No medication or supplement has been proven to reverse or halt cataract formation. Protecting against UV light and not smoking may slow progression. When cataracts significantly impair daily function — driving, reading, recognizing faces — cataract surgery is safe, effective, and very commonly performed. Many people find their vision is substantially better than it has been in years after the procedure.

Eye symptoms that need same-day or emergency care

  • —Sudden curtain or shadow across part of your vision
  • —Sudden shower of new floaters with or without flashing lights
  • —Sudden loss of any vision in one eye
  • —New wavy or distorted central vision (possible wet AMD)
  • —Severe eye pain with halos around lights and nausea (possible acute angle-closure glaucoma)

For sudden vision loss, a curtain across vision, or severe eye pain with nausea — call an ophthalmologist immediately or go to an emergency department. These symptoms can indicate conditions where minutes to hours matter for preserving sight.

This article provides general health education. It does not replace regular eye examinations or clinical management by an ophthalmologist. Age-related eye diseases require specialist care. Gale can help you find an ophthalmologist and prepare for your visit, but eye disease management falls outside what Gale clinicians treat directly.
