Nearsightedness is a common eye condition in which faraway objects appear blurry.
Farsightedness means it’s easy to see things that are far away, but your close-up vision (near vision) is blurry.
Astigmatism is a common vision problem caused by an error in the shape of the cornea.
Presbyopia is an eye condition in which your eye slowly loses the ability to focus quickly on objects that are close.
Conjunctivitis, commonly known as “pink eye,” is an infection or swelling in the outer membrane of your eyeball.
When your eyes are exposed to substances like pollen or mold spores, they may become red, itchy, and watery.
A foreign object in the eye is something that enters the eye from outside of the body.
You use the lens of your eye every day, for everything from reading to driving to bird watching.
Your eyelids are the folds of skin that cover your eyes and protect them from debris and injury.
Three kinds of eyelid bumps are styes, chalazia, or xanthelasma. Most eyelid bumps go away on their own with home treatment, but see your doctor if they continue to grow, affect your vision, or show symptoms of infection, such as discharge.
Entropion refers to a condition in which your eyelid rotates inward. Your eyelashes rub against your eye and cause redness, irritation, and abrasions on the cornea of your eye. Entropion, or eyelid retraction, develops slowly and may not be noticeable in its early stages. Over time, however, the condition worsens until every movement of the eye irritates the surface of the cornea.
An eyelid twitch, or blepharospasm, is a repetitive, involuntary spasm of the eyelid muscles. A twitch usually occurs in the upper lid, but it can occur in both the upper and lower lids. For most people, these spasms are very mild and feel like a gentle tug on the eyelid.
