Millions of Americans are getting ready to view the next eclipse on August 21, but Dr. Russell Van Gelder from the University of Washington School of Medicine warns blindness is a risk if you don't have proper eye protection.
The American Astronomical Society has a list of reputable eclipse glasses and handheld viewers on its website - stamped with this approval code: 12312-2.
You will also need to use solar filter on cameras, binoculars and telescopes and don't use eclipse glasses to look through them... The focused sunlight can melt the filter and damage the eyes.
