An eclipse is an amazing event to see! To view an eclipse safely though, you need to look through special safety glasses or an eclipse viewer. (Regular sunglasses will not protect your eyes! Make sure the safety glasses have the proper ISO and CE certifications.)
There are two ways you can make your own eclipse viewer to view a solar or lunar eclipse safely.
The simplest way is to poke a tiny hole in a piece of paper with a safety pin or sewing pin. Project the light shining through this hole onto another piece of white paper on the ground. You will be able to safely view the eclipse by watching it on the paper on the ground. We did this to view an eclipse while traveling. We hadn’t realized there would be a partial eclipse that day, but managed to scrounge up some paper and a safety pin to make an impromptu viewer.
How To Make An Eclipse Viewer
If you are able to plan ahead for the next eclipse, you can make your own eclipse viewer. We even fashioned ours so we could attach my phone camera to record the projected image and be able to watch a video of the eclipse safely. (Do not attempt to record the eclipse with a camera or video camera without a certified safety viewer on the camera or by capturing the projected image on the paper! You can damage your eyes by viewing the eclipse through a camera without the proper lens.)
This video demonstrates how you can make your own eclipse viewer and how to record the eclipse safely through the viewer.
