UV radiation is considered a cause of cataracts and pterygia (a benign growth of the conjunctiva that is caused by UV light). The association between degenerative eye diseases, such as age-related macular degeneration, and chronic UV radiation exposure is increasing. Researchers reported that photoreceptors in the retina are vulnerable to damage by UV light, suggesting that rods are affected earlier than cones. It is advised to avoid the use of close-range fluorescent lighting, including desk lamps, to reduce the risks of UV radiation.
It is recommended that fluorescent lighting should be replaced by warm-white tubes or incandescent light bulbs of a lower color temperature. If fluorescent lights are continued to be used, a UV filter is highly recommended. The safe range of light appears to be between 2000 and 3500K and a wavelength greater than 500 nm.

The Awareness domain contains research, news, information, observations, and ideas at the level of self in an effort to intellectualize health concepts.
The Lifestyle domain builds off intellectual concepts and offers practical applications.
Taking care of yourself is at the core of the other domains because the others depend on your health and wellness.
