In addition, the human eye is more sensitive to red light, ensuring that this laser is more visible in the dark. Two characteristics of lasers make them dangerous: they are fired over long distances in a narrow beam and do not lose strength as the distance from the laser source increases. This means that the same amount of exposure can be achieved close to and away from the laser source. The eye can focus a laser beam on a very small and intense point on the retina, which can cause a burn or blind spot on the retina. This can lead to temporary or permanent vision loss.
