There are many different ways the brain processes visual information. Weaknesses in a particular kind of visual processing can often be seen in specific difficulties with practical, everyday tasks. The sooner vision loss or eye disease is found and treated, the greater your chances of keeping your remaining vision. Listed are a few of visual disorders; Nearsightedness, or myopia, as it is medically termed, is a vision condition in which close objects are seen clearly, but objects farther away appear blurred. Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus. Astigmatism is a vision condition that causes blurred vision due either to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. Presbyopia is the Inability of the eye to focus sharply on nearby objects, resulting from loss of elasticity of the crystalline lens with advancing age.
