There is a plethora of eye conditions that can affect our eyes. Here are just a few:
Nearsighted (Myopia)-
Nearsighted people's vision is blurry at a distance. Nearsightedness occurs when the eye has too much "plus power" and the eye focuses the light in front of the retina.
Farsighted (Hyperopia)-
Farsighted people's vision is blurry close up worse than far away. Farsightedness occurs because the eye does not have enough power to focus light on the retina.
Astigmatism-
People with astigmatism may be blurry at any distance. Astigmatism occurs when the cornea is not spherical. This causes the light that enters the eye to be focused at two different focal points in the eye.
Amblyopia-
Amblyopia (also known as "lazy eye") is the lack of normal visual development in an eye, despite the eye being healthy. If left untreated, it can cause legal blindness in the affected eye.The most common cause of amblyopia is strabismus (intermittent or constant misalignment of the eyes). Another common cause is a significant difference in the refractive errors (nearsightedness, farsightedness and/or astigmatism) in the two eyes. It is therefore important to correct amblyopia as early as possible, before the brain ignores vision in the affected eye.
Cataracts-
A cataract is a clouding of the eye's lens. Most older people have some degree of lens clouding, which is a normal part of aging. There are many different types and causes of a cataract. Cataracts is like looking through a fogged-up, cloudy window. Cataracts make your visual field appear fuzzy or blurry.
Diabetic Retinopathy-
Diabetic retinopathy is a condition that may develop in people with diabetes. Diabetic retinopathy causes damage to the retina, the light-sensitive layer of tissue located in the back of the eye. It is a serious complication of diabetes that can threaten sight.
Glaucoma-
Glaucoma is the second leading cause of blindness in the United States, making it an important public health priority. Although there are several factors that cause glaucoma, all types of glaucoma are characterized by damage to the optic nerve. This damage prevents the brain from receiving appropriate visual information, resulting in vision loss. If you experience any change in vision, contact an eye care provider immediately for a full examination.
