Sungazing is the unsafe practice of looking directly at the Sun. It is sometimes done as part of a spiritual or religious practice, most often near dawn or dusk.[1] The human eye is very sensitive, and exposure to direct sunlight can lead to solar retinopathy, pterygium,[2] cataracts,[3] and potentially blindness.[4][5][6] Studies have shown that even when viewing a solar eclipse the eye can still be exposed to harmful levels of ultraviolet radiation.[7]
