Age: As with all body systems, the eyes are subject to deterioration and degradation over time. Lens proteins change as the result of aging, toxic exposure, radiation, UV light, or other environmental conditions. Trauma: Injuries and blunt force trauma to the eyes can cause swelling and thickening of the eye’s lens, as well as tears and cuts, which can potentially whiten the lens fibers and cause cataracts. Sunlight and radiation: Long-term exposure to ultraviolet light and exposure to radiation can cause cataracts. Genetic disorders and skin conditions: There are several genetic disorders and hereditary eye conditions that could contribute to cataract development. These include glaucoma, uveitis, and other eye conditions and diseases. Skin conditions such as atopic dermatitis and eczema can also lead to the development of cataracts.
