I'm sorry, but looking at green colors is no better for your eyes than looking at any other color. In fact, to your eyes, any given color of light is still only light. Some cells in the back of your eye respond only to green light, some only to blue light, and some only to red. However, there is no known benefit for your eyes in looking at the color green. There are "colors" of light that are harmful to your eyes. Ultraviolet light (a deep purple that you cannot see) is harmful because it causes cataracts in the lenses (the clear part in the middle of your eye that focuses light). Infrared light (deep red light that you cannot see) can also be harmful because it is really heat! Long exposures to high heat levels can also harm your corneas and lenses.
