Each of those merchandise use scratch-resistant polymer lenses that filter out 100% of ultra-violet and infrared rays and 99.999% of intense seen daylight. They each make the solar look orange. That makes them completely different to photo voltaic eclipse binoculars additionally in Celestron’s EclipSmart vary, which use mylar and make the solar seem bluish-white.
Utilizing the Celestron EclipSmart Photo voltaic Eclipse Glasses to view the solar isn’t any completely different from utilizing any trendy pair of eclipse glasses; you see a really small, orange solar in opposition to a black background.

Nevertheless, by pinching the cardboard housing I discovered a place the place I might see the solar as one barely magnified picture.
For each designs, it is best to maintain them safely wrapped up in plastic till the large day.

Should you can see your eclipse glasses are torn, scratched, or coming unfastened from the cardboard, undoubtedly do not use them.
