On August 21, 2017, a partial eclipse of the sun will be visible throughout all the United States. This rare event occurs when the moon blocks part of the sun from view. It’s an awe-inspiring sight, and one you’ll undoubtedly want to witness. However, there are certain precautions you must take to protect your eyes when viewing a solar eclipse. Here, the ophthalmologists of Hawaii Vision Clinic in Aiea explain how you can get a peek safely.

There is only one time when it is safe to view the sun directly during a solar eclipse: when it’s fully covered by the moon. Otherwise, looking directly at the sun at the wrong moment can permanently damage your retinas, causing permanent vision damage and even blindness. To view the eclipse, you need solar filters. Special “eclipse glasses” or hand-held viewers can be equipped with these lenses, allowing you to see the eclipse without danger.

If you do purchase one of these tools, make sure to check it beforehand for any scratches or signs of damage. Follow the directions precisely and help kids to make sure they are using the device correctly. Ensure your eclipse glasses or viewer are securely in place before you look up at the sun, and don’t remove them until you’ve looked down.

Another way you can view the eclipse safely is via an indirect means, for instance via a video display. NASA will provide a live stream of the eclipse that should do nicely. Another alternative is a pinhole viewer, which projects the image of the sun onto another surface. You can purchase pinhole projectors or even construct them yourself. Here is a handy guide from NASA on how to make one.

While some areas of the United States will experience a total solar eclipse on August 21, this is not the case in Hawaii. This means the precautionary measures described above are a must.
