Trauma to the lens can precipitate cataract formation in the injured eye, and may be related to a blunt force injury, an auto accident, a fist fight or even as a side effect of a necessary eye surgery. Traumatic cataracts often have a rosette appearance. Underlying health conditions increase the risk for developing cataracts including diabetes and high blood pressure. Also, the long term use of corticosteroids and intraocular infection increase the risk of developing cataracts located on the backside of the lens. These cataracts are known as posterior subcapsular cataracts which increase difficulties with glare and reading. Ultraviolet (UV) UV-B light rays have wavelengths between 280nm and 315nm and have more energy than the longer wavelengths of UV-A, which range between 315nm and 400nm. The higher energy UV-B rays are mostly absorbed by the cornea. The eyes need to be protected from UV-B. For example skiing at high altitude without adequate UV-B protection can lead to snow blindness (photokeratitis). The lower energy UV-A rays are able to reach deeper into the eye, mostly being absorbed by the lens. The cumulative exposure of UV-A increases the risk of cataract formation. It is important to protect the eyes from both UV-A and UV-B light since UV damage to the lens (and eyes) is developed over time. Lifestyle choices can increase the risk for developing cataracts including smoking and excessive alcohol consumption. Nutritional deficiencies also play a role in the risk of cataract formation. The lens is bathed in aqueous fluid in front of the lens and vitreous gel behind the lens. Vitamin C, lutein and zeaxanthin, which act to quench oxidative stress, are found in the lens and these fluids. These nutrients must be acquired through foods or nutritional supplementation. A colorful diet of fruits, vegetables and cold-water fish support general eye wellness.   Congenital cataracts are present at birth or shortly thereafter but may even develop during childhood. This type of cataract is often associated with genetic conditions, birth defects, intrauterine infection, or trauma. Proper vision development requires a clear image to be sent to the brain in an infant. Not all congenital cataracts interfere with vision. But, if the cataract does interfere with vision, steps should be taken to avoid lifelong implications.
