But instead of your skin being affected, it\u2019s your eyes. In fact, photokeratitis is sometimes referred to as sunburned eyes, and it can cause some pretty intense eye pain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we\u2019ll discuss the causes, symptoms, and treatment for photokeratitis and explore what you can do to prevent it.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Photokeratitis Causes and Risk Factors<\/h2>\n\n\n\n\n\n<p class=\"wp-block-paragraph\">Photokeratitis happens when unprotected eyes get too much exposure to ultraviolet (UV) light rays. This causes damage to the cells of the cornea (the clear dome covering the eye). Photokeratitis can also affect the conjunctiva, which is the tissue covering the insides of the eyelids and the whites of your eyes. Both main types of UV rays\u2014UVA and UVB\u2014can damage your eyes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Outdoor activities can increase your risk of photokeratitis, especially at high altitudes or in super sunny locations. It can occur when sunlight reflects off of surfaces like snow, ice, water, or sand. Looking directly at the sun\u2014including during a solar eclipse without a viewing device\u2014can also cause photokeratitis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Is Snow Blindness?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Snow blindness is a type of photokeratitis caused by sunlight reflecting off of ice or snow. It\u2019s common near the north or south poles or in high altitudes where the air is thin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People who engage in snow activities in other places may also get photokeratitis. If you go skiing, snowmobiling, or mountain climbing, be sure to use proper eye protection to help avoid snow blindness.<\/p>\n\n\n\n<\/div><!-- .entry-content (split for inline block) -->\n\n<section class=\"wp-blocks__banner has-img white\">\n\t\t\t<div>\n\t\t\t<img decoding=\"async\" src=\"https:\/\/www.warbyparker.com\/learn\/wp-content\/uploads\/2022\/02\/sunglasses-on-book-cta.jpg\" alt=\"Protect those peepers!\" loading=\"lazy\" \/>\n\t\t<\/div>\n\t\t<div class=\"wp-blocks__banner-img\">\n\t\t\t\t\t<h2>Protect those peepers!<\/h2>\n\t\t\t\t<p>Our sunglasses come with a scratch-resistant coating and block 100% of UV rays<\/p>\n\t\t\t\t\t<div class=\"wp-blocks-banner__cta-links\" style=\"flex-wrap:wrap;\">\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.warbyparker.com\/sunglasses\">Shop sunglasses <svg id=\"aa495747-7767-4ea8-bc8e-3e09f9e2a480\" data-name=\"Layer 1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 5.5 9.5\"><path d=\"M5.49,4.61a.87.87,0,0,1,0,.32.73.73,0,0,1-.2.35l-4,4A.75.75,0,0,1,.22,8.22L3.69,4.75.22,1.28A.75.75,0,0,1,1.28.22l4,4A.75.75,0,0,1,5.49,4.61Z\" style=\"fill:#1050D0;fill-rule:evenodd\"\/><\/svg>\n<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n<\/section>\n\n<div class=\"entry-content\"><!-- (reopen for inline block) -->\n\n\n\n<h3 class=\"wp-block-heading\">Other Causes of Photokeratitis<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can get photokeratitis from UV light sources other than the sun, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Tanning beds or booths with artificial UV lights<\/li>\n\n\n\n<li>Certain welding equipment<\/li>\n\n\n\n<li>Floodlights used in photography<\/li>\n\n\n\n<li>Laser lights<\/li>\n\n\n\n<li>Halogen lamps or other very bright lights like highway lights<\/li>\n\n\n\n<li>Electric sparks<\/li>\n\n\n\n<li>Lightning<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Photokeratitis Symptoms<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because photokeratitis is like an eye sunburn, symptoms may take a few hours to show up after sun exposure, much like a sunburn on your skin. And your symptoms will be more severe the longer you\u2019re exposed to UV light. Try to resist the urge to rub your eyes, as that could cause more discomfort (much like rubbing a sunburn on your skin).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible photokeratitis symptoms include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.warbyparker.com\/learn\/why-do-my-eyes-hurt\">Eye pain<\/a><\/li>\n\n\n\n<li>Burning sensation<\/li>\n\n\n\n<li><a href=\"https:\/\/www.warbyparker.com\/learn\/how-to-get-rid-of-red-eyes\">Redness of the eyes<\/a><\/li>\n\n\n\n<li>Blurry vision<\/li>\n\n\n\n<li>Watery eyes<\/li>\n\n\n\n<li>Eye swelling<\/li>\n\n\n\n<li><a href=\"https:\/\/www.warbyparker.com\/learn\/photophobia\">Light sensitivity (photophobia)<\/a><\/li>\n\n\n\n<li>Gritty sensation or the feeling of something stuck in the eye<\/li>\n\n\n\n<li>Headache<\/li>\n\n\n\n<li><a href=\"https:\/\/www.warbyparker.com\/learn\/eye-twitching\">Twitchy eyelids<\/a><\/li>\n\n\n\n<li>Temporary vision changes, such as a halo effect around lights<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Does Photokeratitis Last?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Photokeratitis is temporary and tends to go away with rest after a day or two. However, long-term UV exposure could put you at risk for other <a href=\"https:\/\/www.warbyparker.com\/learn\/eye-disorders-and-eye-diseases\">eye conditions<\/a>, like cataracts and macular degeneration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Photokeratitis Treatment<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s best to see an <a href=\"https:\/\/www.warbyparker.com\/learn\/optometrist-vs-ophthalmologist\">optometrist or ophthalmologist<\/a> to diagnose photokeratitis.
