Eye Care in Old Age: Common Vision Problems & How to Protect Your Sight

Older adults should have a comprehensive dilated eye exam at least once a year, even without noticeable vision problems. If you have diabetes, glaucoma, high blood pressure, or another condition affecting the eyes, your doctor may recommend more frequent visits.

Cataracts can't be completely prevented, since they're largely a natural part of ageing, but wearing UV-protective sunglasses, eating a healthy diet, and avoiding smoking can slow how quickly they develop. When a cataract does start affecting daily life, modern cataract surgery is a safe, effective, and very common solution.

Not always. Some conditions, like cataracts, can be fully treated with surgery. Others, like glaucoma and age-related macular degeneration, can't be reversed, but early detection and consistent treatment can slow or halt their progression, protecting the vision you still have.

Foods rich in vitamins A, C, and E, along with zinc, lutein, and omega-3 fatty acids, are particularly beneficial — think leafy greens, citrus fruits, nuts, eggs, and fatty fish like salmon. See our full guide to the best foods for eye health for more detail.

It depends on overall corneal health and thickness rather than age alone, though LASIK is generally better suited to younger adults with stable eye power. Older adults are often better candidates for procedures like refractive lens exchange or cataract surgery with a premium lens, which address both refractive error and any early lens clouding at once. A thorough eye exam is the only way to know which option fits your eyes.

Normal changes tend to develop gradually over months or years — needing more light to read, slower adjustment to darkness, a few stable floaters, or difficulty with night driving glare. Warning signs, by contrast, appear suddenly: a sharp increase in floaters or flashes, a shadow or curtain across part of your vision, sudden blurred or lost vision, or eye pain. Gradual changes can wait for your next routine exam; sudden changes need same-day attention.

Yes, very effectively in most cases. Dry eye becomes considerably more common with age — affecting an estimated 1 in 8 adults over 65 — often made worse by common medications. Treatment ranges from preservative-free artificial tears and a home humidifier to prescription anti-inflammatory drops for more persistent cases.

Low vision means your eyesight can't be fully corrected with glasses, contact lenses, medication, or surgery, often due to advanced AMD, glaucoma, or diabetic retinopathy. Low-vision aids — magnifiers, specialised lighting, large-print materials, and vision rehabilitation therapy — can help make the most of remaining vision and support continued independence.

Reduced contrast sensitivity, poor depth perception, and a narrower field of vision all make it harder to judge steps, kerbs, and uneven surfaces, which is a major reason vision problems are strongly linked to a higher risk of falls and fractures in older adults. Keeping an updated glasses prescription and good home lighting are two of the simplest, most effective ways to reduce this risk.

A few stable, long-standing floaters are usually nothing to worry about. But a sudden shower of new floaters, especially alongside flashes of light or a shadow across part of your vision, needs same-day evaluation, since it can signal a retinal tear or detachment — a genuine eye emergency.
