Man praising the Sun.
Man sungazing.

Sungazing is an unproven practice that includes gazing at the Sun for nourishment or as a spiritual practice.[1] Looking into the Sun is dangerous, and can cause solar retinopathy and lead to permanent eye damage or blindness.[1][2]

Purpose[edit]

Staring at the sun, a practice called sunning by William Horatio Bates, is one of a series of exercises included in his Bates method, a popular alternative therapy developed in the early 20th century to improve eyesight.[3] The British Medical Journal reported in 1967 that "Bates (1920) advocated prolonged sun-gazing as the treatment of myopia, with disastrous results".[4]

Dangers[edit]

The practice of sungazing is dangerous. Looking directly at the Sun for even brief periods of time may cause blindness or severe damage to the eye.[5] Solar retinopathy, damage to the eye’s retina due to solar radiation,[6] and blindness to varying degrees and persistence frequently result from sungazing during a solar eclipse.[2][7] Although vision loss due to this damage is generally reversible,[6] permanent damage and loss of vision have been reported.[8] Exposure to ultraviolet radiation, such as that produced by the sun, is associated with damage to the eye, including pterygium[9] and cataracts.[10]
