On Monday, August 21, 2017, North America will see the first coast-to-coast total solar eclipse we’ve had since 1979.
While it’s tempting, it’s dangerous to look directly at the eclipse. The sun’s rays are much more powerful during an eclipse than a normal day, and since the retina does not have pain receptors, you can’t feel your eyes being damaged.
Try one of these easy tips to prevent retinal damage or eclipse blindness:
- Purchase eyewear specifically designed for looking at eclipses. Ordinary sunglasses are not a substitute—keep your eyes safe and get the real thing! Refer to the American Astronomical Society (AAS) Reputable Vendors of Solar Filters & Viewers page for more details.
- Install a solar filter on your telescope, camera, binoculars, or other viewing devices. Simply looking through these while wearing solar eyewear will not do! These devices magnify the sunlight, making the rays even more powerful.
- Pinhole projection is another safe option for viewing. This involves passing sunlight through a small opening (such as a hole punched in an index card) and projecting an image of the Sun onto a nearby surface (for example, another card or the ground). Do NOT look at the Sun through a pinhole!
