The way we see is very much like how a camera takes a picture. The front of the eye – the cornea, pupil, and lens – focuses light. This light gets focused onto the retina, the film of the eye that converts light impulses into neurological signals. These signals get transmitted through the optic nerve and to the brain where they are developed into images.
The lens is a metabolically active tissue. Just as a tree lays down one ring a year, the lens lays down several. Over time, it slowly thickens and becomes less optically clear. This causes images to appear hazy. The light entering the lens is also scattered because the lens is not optically clear. This can lead to symptoms such as glare and halos which can be especially bothersome at night.
While the presence of a cataract is a normal aging process, there are other causes for why cataracts can prematurely form. Trauma, use of steroids, or inflammation in the eye (uveitis) are a few reasons. If someone has had eye surgery, this could hasten cataract formation as well. Sometimes, conditions we are born with, for example, high myopia (nearsightedness) can lead to earlier cataract formation as well.
