Eclipse glasses from the last eclipse still tucked away in a drawer? Here's how to check to see if they're still safe.
The total solar eclipse on April 8 is not to be missed. The last such event that will be visible from North America for 20 years, it’s a chance for millions of people to catch an awe-inspiring sight, and many won’t even have to leave their backyards.But while a total solar eclipse may be a rare occurrence, partial and annular eclipses are more common. So many people may have a pair of eclipse glasses tucked away in a drawer somewhere.But are those glasses still safe to use? Here’s how to check.
warns that "staring at the Sun for minutes at a time even with proper filters can still overheat the tissues and fluids in the eye," which can be dangerous. So even though it’s riveting to watch, you’ll want to glance away often to keep all those important eye fluids at a reasonable temperature. No! Firm no! While sunglasses are useful for protecting the eyes from everyday exposure to the sun, they can’t stand up to intense direct sunlight.
says, the next total solar eclipse visible from any point in the contiguous United States will occur in 2044. Totality will only be visible from North Dakota and Montana.The next total solar eclipse that will travel across the lower 48 states from coast to coast is in 2045. This story was reported from Chicago.
