LED Fluorescent light has been the primary type used in businesses, schools and other buildings for decades (plus now in many homes). Can there be a connection between this "cool lighting" and cataract development since their use became so prevalent?

Cataracts occur when the eye's lens, normally clear, becomes opaque and thickened, impeding entry of light. This eventually increases, resulting in loss of vision since light cannot reach the retina. Once the lens has been obstructed it is normally removed surgically and replaced by a plastic lens.
The signs and symptoms of cataracts can be so gradual as to be barely noticeable at first. It may seem at the onset your vision is just a tad blurry; colors may appear less vivid; night vision can be reduced. Viewing a bright light in the dark may give it the corona effect (rays seeming to shoot out from the source). The protein in the lens coagulates, resulting in vision becoming out-of-focus. This thickening eventually gives the eye that characteristic "milky" appearance.
