What Are The 4 Diseases Of The Eye?

Many basic eye health guides focus on cataracts, glaucoma, age-related macular degeneration, and diabetic retinopathy. Cataracts cause the lens of the eye to become cloudy, which can blur vision over time. Glaucoma damages the optic nerve, often in connection with high eye pressure, and can lead to loss of side vision. Macular degeneration and diabetic retinopathy both affect the retina and can disturb sharp central vision.

Common Eye Diseases You May Hear About

These four conditions are common reasons adults lose vision with age, especially without regular checkups. Some progress slowly and quietly, so people might not notice problems until damage is more severe. Eye exams help catch changes early, sometimes before clear symptoms appear. Treatment can slow or limit damage and protect day-to-day tasks like reading, driving, and recognizing faces.

What Is A Cataract?

A cataract is a clouding of the eye's natural lens that usually develops gradually. People may notice dim or blurry vision, glare around lights, or colors that seem faded. Surgery can replace the cloudy lens with a clear artificial one when daily activities are affected.

How Does Glaucoma Affect Vision?

Glaucoma damages the optic nerve, often linked with high eye pressure, though pressure can also be normal. Early on, there may be no obvious symptoms, and side vision slowly shrinks over time. Drops, laser treatment, or surgery are often used to protect the nerve from further damage.

What Happens In Macular Degeneration?

Age-related macular degeneration harms the macula, the part of the retina responsible for sharp central vision. People may see blurred spots, distorted lines, or a dark patch in the center of what they are looking at. Certain forms can be treated with injections or lifestyle changes to slow worsening.
