Failing eyesight is common with age, but much of it is treatable or preventable. Cataract surgery restores vision safely, while conditions like glaucoma need early detection to save sight.
Cataract: cloudy, dim vision and glare — treated with simple surgery
Glaucoma: silent loss of side vision — needs early detection
Macular degeneration: loss of central vision — needs prompt care
Diabetics: yearly retinal screening is essential
Regular eye checks catch problems early; good vision prevents falls
When to see a doctor urgently
Sudden vision loss, or a curtain/shadow across vision — emergency
Sudden eye pain with redness, halos and nausea (acute glaucoma — urgent)
New flashes and many floaters (possible retinal detachment)
Regular eye checks save sight. Many causes of poor vision in older age are treatable, and some (like glaucoma) are silent until sight is lost — so regular eye checks matter. Sudden vision changes are emergencies. MedDroid gives general information, not a diagnosis.
Frequently asked questions
Is cataract surgery safe for the elderly?
Yes — it is one of the safest, most successful operations, and it restores vision, improves independence and reduces fall risk.
How often should older people get eye checks?
At least every 1–2 years, and yearly for diabetics, to catch treatable conditions like glaucoma and diabetic eye disease early.
What causes vision loss in old age?
Common causes are cataract, glaucoma, macular degeneration and diabetic eye disease — most treatable or manageable if caught early.
