Several technologies to restore sight to retina-damaged eyes are making headway--one seeks to begin human trials in the U.S. and another has already hit the market in Europe

Yellowing of the eye lenses changes the array of incoming light wavelengths, which can affect circadian rhythms, including sleep patterns. Katherine Harmon reports

The earlier diabetic retinopathy, macular degeneration and glaucoma—the three most prevalent diseases causing blindness—can be diagnosed, the more successfully they can be treated.
