Understanding the most prevalent eye diseases is the first step toward protecting your sight. Early detection saves vision — learn the signs before it's too late.
Glaucoma damages the optic nerve gradually and painlessly. Most people have no symptoms until significant, irreversible vision loss has already occurred. It affects over 3 million Americans — and half don't know they have it. Regular eye pressure checks are the only reliable early warning.
Learn About Glaucoma →A group of eye conditions that damage the optic nerve, usually caused by abnormally high pressure in the eye. It's the leading cause of irreversible blindness in the US.
A clouding of the eye's natural lens that lies behind the iris and pupil. Cataracts are the most common cause of vision loss in people over 40 and the principal cause of blindness in the world.
Age-related macular degeneration (AMD) destroys sharp, central vision needed for seeing objects clearly. It affects the macula — the part of the eye that allows you to see fine detail.
A diabetes complication that damages blood vessels in the retina. It's the most common cause of vision loss among people with diabetes and the leading cause of blindness in working-age adults.
A condition in which the eyes don't produce enough tears, or produce tears that evaporate too quickly. It's one of the most common complaints seen by eye doctors, affecting millions worldwide.
The most frequent eye problems in the US. Refractive errors include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. All are easily corrected with glasses, contacts, or surgery.
Inflammation or infection of the conjunctiva, the transparent membrane that lines your eyelid. When small blood vessels become inflamed, they're more visible, causing the white of the eye to appear reddish or pink.
The most common cause of vision impairment in children. Amblyopia occurs when one eye develops stronger vision than the other — the brain begins to rely on the stronger eye, causing the weaker eye to worsen.
A medical emergency in which the retina peels away from its underlying layer of support tissue. Without prompt treatment, more of the retina detaches, increasing the risk of permanent vision loss.
