  1. Eye conditions common in albinism may include:

    Nystagmus, irregular rapid movement of the eyes back and forth, or in circular motion.

    Strabismus, eye misalignment ("crossed eyes" or "lazy eye").

    Refractive errors such as myopia or hyperopia and especially astigmatism are more likely[13]

    Photophobia, hypersensitivity to bright light and glare.

    Foveal hypoplasia, underdevelopment of the fovea, the center of the retina

    Optic nerve hypoplasia, underdevelopment of the optic nerve

    Abnormal decussation (crossing) of the optic nerve fibers in the optic chiasm[14]

    Amblyopia, decrease in acuity of one or both eyes due to poor transmission to the brain, often due to other conditions such as strabismus.

    Organisms with albinism usually have impaired vision due to one or more of the listed conditions. While a person with albinism may suffer from common refractive errors like nearsightedness or farsightedness, the visual problems particularly associated with albinism arise from a poorly-developed retinal pigment epithelium (RPE) due to the lack of melanin[citation needed]. This degenerate RPE causes foveal hypoplasia (a failure in the development of normal foveae), which results in eccentric fixation and lower visual acuity, and often a minor level of strabismus. Nystagmus is usually seen, as is photophobia or light sensitivity (see below).

    The iris is a sphincter with pigmented tissue (which makes up the color of the eyes) that contracts to limit the amount of light that can enter through the pupil and relaxes again to allow for better vision in darkness. This mechanism can be observed in humans and mammals (like in cat's eyes) and is needed because too much light is uncomfortable or even painful and decreases vision. In people with albinism, the iris does not have enough pigment to block the light, thus the decrease of pupil diameter is only partially successful in reducing the amount of light that enters the eye.[citation needed]. Additionally, the improper development of the RPE, which in normal eyes absorbs most of the reflected sunlight, further increases glare due to light scattering within the eye.[14] The resulting sensitivity (photophobia) generally leads to a dislike of and discomfort in bright light, but does not prevent people with albinism enjoying the outdoors, especially when using sunglasses and/or brimmed hats.[3]

    The lack of pigment also makes the skin unusually sensitive to sunlight and thus susceptible to sunburn, so people with albinism should either avoid prolonged exposure to bright sunlight or protect their skin.

    Vision aids

    Glasses and other vision aids, large-print materials and closed captioning, as well as bright but angled reading lights, can help individuals with albinism, even though their vision cannot be corrected completely. Some albinistic people do well using bifocals (with a strong reading lens), prescription reading glasses, and/or hand-held devices such as magnifiers or monoculars.[3] Contact lenses may be colored to block light transmission through the iris. Some use bioptics, glasses which have small telescopes mounted on, in, or behind their regular lenses, so that they can look through either the regular lens or the telescope. Newer designs of bioptics use smaller light-weight lenses. Some US states allow the use of bioptic telescopes for driving motor vehicles. (See also NOAH bulletin "Low Vision Aids".)

    Although still disputed among the experts,[who?] many ophthalmologists recommend the use of glasses from early childhood onward to allow the eyes the best development possible.

    Optometrists or ophthalmologists who are experienced in working with low vision patients can recommend various optical aids. Some low-vision clinics provide these aids on trial loan, with instruction in their use


  2. Albinos have no pigment in their iris...their eyes are pink. so they are succeptable to sun damage

  3. Those born with albinism have vision problems of varying degrees, such as nystagmus or involuntary eye movement, nearsightedness or farsightedness, astigmatism, and extreme sensitivity to light (called photophobia).
