HOW TO SAFELY WATCH AND ECLIPSE

SCIENCE & TECHNOLOGY 283

Never look directly at the Sun without proper eye protection. You can seriously hurt your eyes, and even go blind.

Safely Watch a Solar Eclipse

The only way to safely view the Sun – eclipsed or not – is to either project or filter the Sun’s rays.

The Sun’s UV radiation can burn the retinas in the eyes leading to permanent damage or even blindness. This can occur even if your eyes are exposed to direct sunlight for just a few seconds.

Eclipse Glasses:

If you are not the DIY type, check online or with your local natural history, space museum, or astronomy club for where to get proper eclipse glasses.

Welder’s Goggles:

NASA recommends welder’s glasses rated 14 or higher. These can be found at your local welding supply store. Keep in mind that welder glass grading may be different in different countries.

Use Proper Filters:

You can use special solar filters to watch the Sun during a solar eclipse, but use the proper type of solar filter that is designed for eclipses. Check that filters do not crack under the Sun’s magnified and focused intensity. Solar filters must be treated with care or they can quickly become damaged and unsafe to use.

How Not to Watch Solar Eclipses

According to NASA, the following materials should never be used to view a solar eclipse:

  • Don’t use color film.
  • Don’t use medical X-ray film with images on them.
  • Don’t use smoked glass.
  • Don’t use any kind of sunglasses.
  • Don’t use CDs or computer floppy disks.
