On 8/21/17, a total solar eclipse will be visible in a path that travels across the entire United States. All areas outside that path will see a partial eclipse. But how do you safely look at the eclipse without damaging your eyes? We got a lot of your #AskAnEyeDoc questions about safely watching the eclipse, and Dr. Moos is here to provide some details. She recommends watching the eclipse on TV because that's the safest way. Another safe alternative is to use a a pinhole projector with your back to the sun. But since a lot of people are going to look anyway, here's what you need to know. A really good option is buying glasses designed to look at the eclipse. There are both disposable and more durable versions available at most hardware stores as well as online. Just be careful if you buy online because there are a lot of counterfeit products that can damage your eyes. You can also wear a welding mask or goggles, but be sure the filter is rated at least #14. Less than that offers some protection but it's not designed to protect from directly staring at the sun. You should NOT use sunglasses or layers of sunglasses to look at the eclipse. The sun is extremely bright and even layers of sunglasses can't filter out enough to protect your eyes. Finally, don't look at the eclipse with your naked eye or with a telescope or binoculars. The sun is incredibly powerful and your eyes are too precious to risk for a couple minutes of excitement.
