Cataracts

A cataract is a clouding of the natural lens, the part of the eye responsible for focusing light and producing clear, sharp images. They usually form in both eyes, though they typically manifest in one eye first. Symptoms include a loss of visual clarity and contrast between shapes and colors.

There are a variety of reasons why cataracts form, but some of the most common include, but are not limited to, injury and trauma, genetics, radiation exposure, advanced age, diabetes, and hypertension.

Since cataracts have a relatively wide range in severity, treatment is surgical and is reserved only when the cataracts have begun to interfere with everyday activities such as reading and driving.
