A cataract is a clouding, opacity, yellowing, or accumulation of fluid in the lens of the eye that results in a loss of vision and interferes with your lifestyle. Most cataracts are related to aging, and by the time you reach the age of 70 most people will show some signs of cataracts. Age related cataract may occur in one eye first but with time will usually be present in both. The lens is a clear part of the eye that helps to focus light, or an image, on the tissue lining the back of the eye called the retina. The retina is lined with the receptor cells that transform light particles into electrical impulses. A healthy lens is transparent due to the special proteins that help the layers repeat in a regular pattern that causes the least interference and passes the most light through.

The lens does some filtering of the ultraviolet radiation from the sun preventing UV from reaching high levels in the retina. While the lens filters out UV in both the A and B bands, it filters virtually all of the UV radiation between 320 to 400 nan meters and the proteins responsible oxidize over time. Free radicals also increase and the lens yellows and loses transparency as water starts accumulating in-between the layers.

Eye surgery for glaucoma and other conditions can lead to cataract formation. Certain health conditions like diabetes can also cause cataracts, occasionally very rapidly and in some instances also rapidly reversible. Unfortunately, they are usually permanent. Prescription steroid medications used long term can result in cataract development. Traumatic cataracts result after serious eye injuries but usually will not progress over time like age related cataracts. Infants occasionally are born with cataracts or develop them in early childhood, These cataracts may be so small and enough off the line of sight that they do not affect vision. While technically a cataract, I feel an opacity needs to cause lifestyle interruptions before they should be labeled as a cataract. Cataracts are best described by function rather than form. If they do interfere with your daily life, the lenses may need to be removed. Radiation exposure can result in cataracts if the dose is high enough or accumulates over repeated exposure.
