NASA is alerting people about unsafe eclipse-viewing glasses as parts of the country prepare for a solar eclipse. <\/p>\n
A total solar eclipse, in which the moon entirely blocks the sun, will last for nearly 3 minutes, depending on where in the country you watch. But you shouldnt look at the sun, even during partial and full eclipses, through a camera or ordinary sunglasses, NASA says. <\/p>\n
The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, federal websites say, pointing to eclipse glasses and handheld solar viewers as examples of proper devices. <\/p>\n
A total solar eclipse will occur Aug. 21 for people watching from parts of the country. Also, a partial eclipse will last for two to three hours and be visible to everyone in North America. <\/p>\n
For eclipse glasses, the federal government recommends that people use American Paper Optics, Rainbow Symphony, Thousand Oaks Optical or TSE 17. <\/p>\n
Even when wearing eclipse glasses, one should not look at the sun through a camera, telescope, binoculars or other devices, because you could be seriously injured. <\/p>\n
Eclipse glasses are unsafe after three years, according to NASA, and shouldnt have scratches or be wrinkled. <\/p>\n
NASA also instructs people to use eclipse glasses that have an ISO international standard icon with reference number 12312-2. <\/p>\n
