During a solar eclipse, solar glasses and filters must be used during all phases except totality. Once the Sun is fully obscured (between second and third contact), you can safely remove
We used to say that you should look for evidence that they comply with the ISO 12312-2 international standard for filters for direct viewing of the Sun. But then we discovered that some eclipse glasses
The only safe way to look directly at the sun during an eclipse is through special-purpose solar filters, like eclipse glasses or handheld solar viewers. Remember the only safe time to look at the sun
Learn the four basic rules for using eclipse glasses to make the most of viewing a solar eclipse while maintaining your eye safety.
Learn all about solar control glass in this comprehensive guide. Discover its benefits, types, and applications, and how it can improve the energy efficiency.
When watching a partial or annular solar eclipse directly with your eyes, you must look through safe solar viewing glasses (“eclipse glasses”) or a safe handheld solar viewer at all times.
Solar eclipse glasses are vital on April 8, but do you actually know how to use them safely—and if/when you can take them off?
