Can you use the Eclipse Glasses with a camera, telescope,or binoculars?
No! Do not look at the Sun through a camera, a telescope, binoculars, or any other optical device while using your eclipse glasses or handheld solar viewer — the concentrated solar rays could damage the filter and enter your eye(s), causing serious injury. Special filters exist for when using other optical devices. THESE SOLAR ECLIPSE DEVICES ARE NOT TO BE USED WITH OTHER OPTICAL DEVICES, such as cameras, telescopes, binoculars, etc.
Can you wear these Eclipse Glasses over daily wear (prescription) glasses?
If you normally wear eyeglasses, keep them on. Put your eclipse glasses on over them. You may need to hold the eclipse glasses to your face to ensure a safe fit.
Can I just use regular sunglasses to view the Eclipse?
No. You cannot wear sunglasses to view the solar eclipse. Please see the safety section for more information.
Are there other safe ways to view the Eclipse?
If you don’t feel safe or comfortable using solar eclipse glasses to view the eclipse, another way to watch it is to create a pin hole camera. https://eclipse.aas.org/eye-safety/projection
I have an old pair of Eclipse Glasses, can I re-use them?
If you are unsure whether the filters are scratched, torn, punctured, or damaged, or how they have been stored or transported since the last time you used them (such as placing them in your pocket, purse, or luggage), it is better to err on the side of caution and buy a new pair.
Do Eclipse Glasses expire?
To be safe, do not use the glasses 3 years after purchasing them.
Solar Eclipse Eye Safety White Paper by Canadian University of Waterloo Professor.
Dr. Chou is the world’s leading expert on solar eclipse safety and has written the ISO standard for eclipse glasses. An excerpt from Dr. Chou’s white paper on Eye Safety and Solar Eclipses.
“Total solar eclipses are arguably the most spectacular astronomical events that anyone will experience in their lives. While annular and partial solar eclipses aren’t nearly as impressive, they nevertheless attract a great deal of public interest. Astronomers (both amateur and
professional) and other enthusiasts travel around the world to observe and photograph solar eclipses. This document is for them, i.e., for astronomers and other experts — including educators as well as medical and eye-care professionals — who may find themselves in the position of coaching laypersons through a solar eclipse and who want to understand in detail the principles of eye safety for observing the Sun.”
