WebBecause the different colors of light now have different focal points, there is no single position where all the light coming from the lens is in focus. Instead, there is an optimal focal plane for each wavelength of light, and all colors can not simultaneously be in focus. WebCommon disorders include cataracts (clouding of the eye lens) and age-related macular degeneration (AMD), a condition that causes loss or distortion of vision. Damage: Injuries may cause a detached retina or a clouding of the cornea or lens. This damage can block light from passing through your eye and cause vision loss.
