What is Sun Gazing?
Sun gazing (also known as sun-eating) is a strict practice of gradually introducing sunlight into your eyes at the lowest ultraviolet-index times of day – sunrise and sunset.
Those who teach the practice say there are several rules to the practice. First, it must be done within the hour after sunrise or before sunset to avoid damaging the eyes.
Second, you must be barefoot, in contact with the actual earth – sand, dirt or mud; and finally, you must begin with only 10 seconds the first day, increasing by 10 second intervals each day you practice. Following these rules make the practice safe, says sources.
