As eyes intently look to the sky for a glimpse of The Great American Eclipse this Monday, make sure all pairs are protected.“The only one safe way to look directly at the sun is through special purpose solar filters, which are called solar eclipse glasses or hand-held solar viewers,” said Dr. Norman Rone. “An eclipse is a rare and striking phenomenon you won’t want to miss, but it is vital you protect your eyes.”Do not look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device, Rone says.Similarly, do not look at the sun through a camera, telescope, binoculars, or any other optical device while using your eclipse glasses or hand-held solar viewer — the concentrated solar rays will damage the filter and enter your eyes, causing serious injury.While it may be tempting to brush off warnings against looking up at the eclipse with bare eyes, don’t. “Exposure of the retina to intense visible light causes damage to its light-sensitive rod and cone cells,” said Rone.
