Astigmatism

In an eye with astigmatism, light fails to come to a single focus on the retina to produce clear vision. Instead, multiple focus points occur, in front of the retina or behind it, or both. This causes blurred vision at all distances. Astigmatism is a type of that occurs when the cornea is irregularly shaped, … Continued

Presbyopia (The aging eye condition)

Presbyopia, also known as the aging eye condition is the normal loss of near focusing ability that occurs with age. Presbyopia is caused by the hardening and loss of flexibility of the natural lens due to changes within the proteins of the lens and muscle fibers. As a result, the eye is not able to … Continued

Hyperopia (Farsightedness)

Hyperopia, farsightedness, is a common eye condition in which you can see distant objects clearly, but objects nearby may be blurry. Hyperopia, farsightedness, is a common refractive error that affects approximately one quarter of the population. Hyperopia is caused by a flat cornea or an eyeball that is shorter than normal,resulting in the visual image … Continued

Myopia (Nearsightedness)

Myopia, nearsightedness, is a common eye condition. If you are nearsighted, you can see objects near to you clearly, but objects farther away are blurry. It occurs when the shape of your eye causes light rays to bend incorrectly – the light rays focus at a point in front of the retina, rather than directly … Continued
