When developing for long amounts of time, the light that usually coming from the computer monitor is able to either damage or hurt your eyes. This one defenitely applies to the widgets and windows on the screen, not just the game itself.
According to the Review of Optometry, UV light is dangerous to the skin. Aside from that, it is also dangerous to the eyes. In this case, it is important that you can protect them from the UV damage. This kind of light affects the front of the eye (cataract formation), while the blue one causes damage to the back of the eye (risk of AMD). Apparently, 90% of all the the light sources are estimated to be the LED lighting. So, the exposure to the blue one is everywhere and only increasing.
