UV and natural light for monitors

Increasingly the average human spends a huge proportion (probably too high a proportion) of their day in front of a computer monitor. This appears unlikely to change in the shortterm, but some health consequences could be alleviated by putting UV and natural light emitters on monitors. A low level of UV light would simulate tanning giving the user of the monitor a healthy complexion and allowing Vitamin D production; natural light is thought to reduce seasonal affective disorder and improve mood.
