Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. The degree of your nearsightedness determines your ability to focus on distant objects. People with severe nearsightedness can see clearly only objects just a few inches away, while those with mild nearsightedness may clearly see objects several yards away.
Farsightedness (hyperopia) is a common vision condition in which you can see distant objects clearly, but objects nearby may be blurry. The degree of your farsightedness determines your focusing ability. People with severe farsightedness may see nearby objects less clearly than distant objects, while those with mild farsightedness may be able to clearly see objects that are closer.
With all types of glaucoma, the nerve connecting the eye to the brain is damaged, usually due to high eye pressure.
Glaucoma is not just one eye disease, but a group of eye conditions resulting in optic nerve damage, which causes loss of vision. Abnormally high pressure inside your eye (intraocular pressure) usually, but not always, causes this damage.
Clouding of the normally clear lens of the eye that can affect vision and typically happens over time. A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car, especially at night, or see the expression on a friend’s face.
A common imperfection in the eye’s curvature that affects vision. Can be corrected through proper eyewear or through surgery. Astigmatism is a common eye condition that’s easily corrected by eyeglasses, contact lenses, or surgery. Astigmatism is characterized by an irregular curvature of the cornea.
The gradual loss of your eyes’ ability to focus actively on nearby objects is a not-so-subtle reminder that you have reached middle age. A natural, often annoying part of aging, presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 60.
The term “macular degeneration” includes many different eye diseases, all of which affect central, or detail vision. Age-related macular degeneration is the most common of these disorders, mainly affecting people over the age of 60. Although there are many types of macular degeneration, age-related macular degeneration (AMD or ARMD) is the most common type.
Keratoconus is an condition in which the shape of the cornea becomes distorted. The cornea is a clear structure that covers the front of the eye and allows light to enter the eye. In a healthy eye, the cornea curves like a dome. In an eye with keratoconus, the center of the cornea slowly thins and bulges so that it sags and has a cone shape.
