Solar Eclipse Eye Safety Tips from Lighthouse Guild
Excitement continues to build for the solar eclipse that will take place on Monday, August 21. Lighthouse Guild offers five tips to help protect your eyes while watching this extraordinary event.
• The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” or handheld solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun. They transmit thousands of times too much sunlight.
• If you normally wear eyeglasses, keep them on. Put your eclipse glasses on over them, or hold your handheld viewer in front of them.
• Stand still and cover your eyes with your eclipse glasses or solar viewer before looking up at the bright sun. After looking at the sun, turn away and remove your filter. Do not remove it while looking at the sun.
• Do not look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device.
• Do not look at the sun through a camera, telescope, binoculars, or any other optical device while using your eclipse glasses or handheld solar viewer – the concentrated solar rays could damage the filter and enter your eyes causing serious injury.
