Staring at an eclipse without adequate eye protection can cause retina damage and severe eye injury — you’ll need solar eclipse viewing glasses to observe it safely. A number of U.S. retailers and entities, including Warby Parker, MyEyeDr., Smoothie King and Sonic Drive-In are giving away these glasses for free.
If you can’t get a hold of the special solar eclipse glasses, another way to safely view the eclipse is through a pinhole projector that is easily made at home with household items. Check out the video below for step-by-step instructions.
