Solar viewers are many thousands of times darker than even the darkest sunglasses, NASA says in an article devoted to eclipse viewing safety. While NASA doesn’t officially approve any particular brand of solar viewer, it says people viewing a partial or annular solar eclipse must look through solar viewing glasses, also known as eclipse glasses, or handheld solar viewers to avoid permanent eye injury. with different percentages of coverage, and a clock showing the path of the eclipse as it heads South. The space agency, which will be providing live coverage of the event, also has an interactive map that shows the main route of the eclipse, areas of the U.S. The NASA map shows that the Northeast will only see a 15-20% solar eclipse. In other areas of the Southwest, the sun will appear as a crescent during the eclipse’s peak. 14 is officially known as an annular eclipse, when the moon passing in front of the sun leaves a circular fringe of light around its edges, which is what gives the eclipse its “ring of fire” nickname. “Our friends in the Southwest, from Texas to California, will have the best view of the solar eclipse and also the best odds of clear skies,” McCleary says.Īn eclipse map on NASA’s website shows that at the peak of the eclipse the sun will be blocked by 90% along a path stretching from Oregon, California, Nevada, Utah, Arizona, New Mexico and Texas, when it will show as a ‘ring of fire.’ ![]() ![]() “The concentrated solar rays could damage the filter and enter your eyes, causing serious injury,” the society says. “The lenses of a camera focus all that bright sunlight onto a small spot on the film/sensor, and without a filter to attenuate some of the sunlight, the sensor will be damaged at least temporarily,” she says.Įven if the viewer is wearing special filters or eclipse glasses over their eyes, they can still damage their eyesight by looking at the sun through an unfiltered camera, binoculars or telescope, according to the American Astronomical Society. “The same will be true for a camera,” McCleary says. Think of a child using a magnifying glass and the sun’s rays to burn holes in a piece of paper, she says. ![]() With a very powerful light source like the sun, all that light gets focused on one tiny spot and does a nice job of burning holes in your retina,” says Jacqueline McCleary, Northeastern assistant physics professor and observational cosmologist. “The lenses in your eyes focus light onto the retina of your eyes.
