Batesville, In. — As people prepare for the August 21 “Great American Solar Eclipse” caution has been issued about the eyewear used to safely view the celestial event. Only select brands have been certified safe to use.
To properly and safely view the event, you need solar filter glasses that are in good condition and meet the minimum International Organization for Standardization requirements or in this case ISO-12312-2. In short, to meet the standard the glasses must block 99.99 percent of the sunlight to be safe. Doctors say permanent damage to the retina could result.
Retail giant Amazon recently issued hundreds of refunds to people with inferior glasses.
