A total solar eclipse is about as bright as a full moon, he said. Anyone viewing a partial solar eclipse should use protective eyewear the entire time they’re watching.įor those in the country who will witness a total solar eclipse, the roughly two-minute period of totality is safe to view without eclipse glasses or filters, according to Rick Fienberg, spokesperson for the American Astronomical Society. Many parts of the country will only see a partial solar eclipse, and even the parts that will see a total solar eclipse will see a partial eclipse before and after totality. The most dangerous time during an eclipse is when the sun is not fully blocked by the moon, during what’s known as a partial solar eclipse. Looking directly at the sun can cause temporary or permanent damage to the retinas, though it will not cause you to lose your vision entirely. We have a natural aversion to staring at the sun, but it’s possible to overcome that by force of will,” Van Gelder said. “There are not pain fibers in the back of the eye, unlike our skin. When we look directly at the sun, the part of our eye that is in danger is the retina, a light-sensitive layer that can easily be damaged by high levels of light. Van Gelder notes that anyone who’s taken a magnifying glass out on a sunny day to burn holes in leaves has seen how powerful the sun’s rays are. Why is it so dangerous to look at the eclipse without glasses? Anyone who uses these devices without protection can increase the amount of damage to their eyes as they amplify the sun’s rays. There are also special filters for telescopes, binoculars and cameras. In comparison, ordinary sunglasses only block about 60% of light rays. Russell Van Gelder, a clinical spokesperson and past president of the American Academy of Ophthalmology. “They’re much darker and much closer to a welder’s mask in blocking light than traditional sunglasses,” said Dr.
