Solar Eclipse Safety

A solar eclipse occurs when the moon completely or partially covers the sun. This is a fascinating spectacle, but it is very important to guard against temporary or permanent damage to the eyes.

Here are some tips that will help you enjoy watching an eclipse safely:

  1. Safety Focus: Ensure your eyes are protected at all times by using approved solar eclipse viewers that meet international standard ISO 12312-2 for safe viewing. Make sure that the glasses are not damaged or scratched before use. Sunglasses, even those with a very dark tint are not sufficient protection.
  2. Don’t Get Burned! Staring at the sun without protection, may cause damage to your retina (the tissue at the back of your eye) called “solar retinopathy.” This damage can occur without any sensation of pain. The injury can be temporary or permanent. Visit your local doctor of optometry immediately if an accident occurs.
  3. Go Indirect – Project: If you can't find eclipse viewers, make a pinhole projector to watch the eclipse. It’s important to only watch the screen, not the sun. Never look at the sun through the pinhole.
  4. Watch Online: Check out NASA's recording of the 2017 eclipse.
  5. Check It Out: If you experience any problems with your eyes or vision after the eclipse, visit your optometrist promptly.
