The genes that cause albinism result in abnormal development of the nerve connections between the eyes and the brain. The retina and the iris (the colored portion of the eye) are also affected by albinism.People with Albinism nearly always have impaired vision. They are unable to produce melanin and this means their eyes do not develop normally before birth. Extreme long or short sightedness is common.

Cataracts" (A clouding of the eye lense)

Clumps of protein reduce the sharpness of the image reaching the retina.
The lens consists mostly of water and protein. When the protein clumps up, it clouds the lens and reduces the light that reaches the retina. The clouding may become severe enough to cause blurred vision. Most age-related cataracts develop from protein clumpings. When a cataract is small, the cloudiness affects only a small part of the lens. You may not notice any changes in your vision. Cataracts tend to "grow" slowly, so vision gets worse gradually. Over time, the cloudy area in the lens may get larger, and the cataract may increase in size. Seeing may become more difficult. Your vision may get duller or blurrier.
