Green laser pointers as many would think would not cause as much damage to the retina as a red laser.
However, as has been learned through recent research that is just not the case. The problem itself is not with the green light that these laser pointers emit, it is with the invisible light that is produced which will cause damage to the retinas. It is not necessarily that the lights are too bright, but that the manufacturing process of many of these green laser pointers is inadequate and does not have enough of a filter to keep the invisible light at a safe level.
