==Damage== The damage to eyes from ultraviolet radiation can be serious and permanent due to damage to the retina. Wearing sunglasses can prevent some harm, depending on the UV rating.<ref>{{cite web |last1=Turbert |first1=David |title=The Sun, UV Light and Your Eyes |url=https://www.aao.org/eye-health/tips-prevention/sun |website=www.aao.org |date=29 May 2024 |access-date=11 June 2024}}</ref> People who have had cataract surgery, received photodynamic therapy, or are under the effects of photosensitizing medications have an increased risk of eye damage due to sungazing. During a solar eclipse, the risk of damage is especially high. When looking at the eclipsed Sun directly, the eyes dilate due to the reduced visible light. Without proper protection, this leads to a larger area for the Sun's UV rays to penetrate and do damage. This can be hard to prevent as the retina has no pain receptors.<ref>{{cite web |title=Eclipse Viewing Safety |url=https://science.nasa.gov/eclipses/safety/ |website=science.nasa.gov |date=24 February 2022 |access-date=11 June 2024}}</ref><ref>{{cite web |title=2024 Solar Eclipse |url=https://www.urmc.rochester.edu/eye-institute/healthy-eyes/2024-solar-eclipse.aspx |website=www.urmc.rochester.edu |access-date=11 June 2024}}</ref>

==Movements== Referred to as ''sunning'' by William Horatio Bates as one of a series of exercises included in his Bates method, it became a popular form of alternative therapy in the early 20th century.<ref name=Chou2004>{{cite journal | journal = Review of Optometry | url = http://www.revoptom.com/content/d/therapeutics/c/17353/ | title = Exposing the Secrets of Fringe Eye Care | first = Brian | last = Chou | volume = 141 | issue = 9 | date = 15 September 2004 | access-date = 1 May 2011 | archive-date = 13 December 2013 | archive-url = https://web.archive.org/web/20131213073339/http://www.revoptom.com/content/d/therapeutics/c/17353/ | url-status = dead }}</ref> His methods were widely debated at the time but ultimately discredited for lack of scientific rigor. The ''British Medical Journal'' reported in 1967 that "Bates (1920) advocated prolonged sun-gazing as the treatment of myopia, with disastrous results".<ref>{{cite journal |doi=10.1136/bmj.3.5559.212 |title=Solar retinopathy |year=1967 |last1=Ridgway |first1=A.
