Sungazing
Sungazing is a practice that includes gazing at the sun for nourishment or as a spiritual practice. Looking into the sun is dangerous, and can cause solar retinopathy and lead to permanent eye damage or blindness.[1][2]
Purpose
Proponents of sungazing claim increased energy levels and decreased appetite; as with other forms of inedia, this claim is not considered credible due to the lack of scientific studies confirming it.[3][4]
Sungazing is also part of the Bates method, an alternative therapy intended to improve eyesight. Ophthalmologists do not regard the method as useful.[5]
Dangers
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.[6] Solar retinopathy, damage to the eye’s retina due to solar radiation,[7] and blindness to varying degrees and persistence frequently result from sungazing during a solar eclipse.[2][8] Although vision loss due to this damage is generally reversible,[7] permanent damage and loss of vision have been reported.[9] Most eye care professionals advise patients to avoid looking directly at the sun.[10] Exposure to ultraviolet radiation, produced by the sun, is associated with damage to the eye, including pterygium[11] and cataracts.[12]
At least one practitioner continued the practice despite clear evidence of eye damage.[1]
