(WTVG) - The next total solar eclipse is coming April 8, 2024. Partial solar eclipses will be visible locally in 2045, 2052, 2071 and 2078. If you have ISO-compliant glasses that are safe, here's what NASA says about reusing them:
"Note: If your eclipse glasses or viewers are compliant with the ISO 12312-2 safety standard, you may look at the uneclipsed or partially eclipsed Sun through them for as long as you wish. Furthermore, if the filters aren't scratched, punctured, or torn, you may reuse them indefinitely. Some glasses/viewers are printed with warnings stating that you shouldn't look through them for more than 3 minutes at a time and that you should discard them if they are more than 3 years old. Such warnings are outdated and do not apply to eclipse viewers compliant with the ISO 12312-2 standard adopted in 2015."
