Safely Viewing an Eclipse
Your parents have probably told you never to look directly at the sun. The reason for this is that you can cause permanent damage to your eyes, even blindness, in just a few seconds, because the sun’s rays are so bright. While sunglasses can provide adequate protection for a sunny day, they are not safe for viewing an eclipse.
You should also never use binoculars or look into the lens of a telescope to view an eclipse. Fortunately, eclipse glasses can be purchased online or at a local museum.
What makes eclipse glasses so special? Their lenses contain filters that are thousands of times darker than sunglasses. In fact, the lenses are so dark that the only thing you can see with them is the surface of the sun. The only time it is safe to remove these glasses is for the brief period that the moon entirely covers the surface of the sun. Just before any part of the sun becomes visible again, you should put your solar glasses back on.
