Eye safety during Sunday's solar eclipse

Sunday's (May 20) partial (annular) solar eclipse should not be viewed without proper eye protection. 

Like other types of solar eclipses, annular eclipses are spectacular but potentially dangerous skywatching events. Care must be taken to observe them properly, or serious and permanent eye damage — including blindness — could result.

Warning: Never look directly at the sun, either with the naked eye or through telescopes or binoculars without the proper filters.

To safely observe the May 20 annular eclipse, you can buy special solar filters to fit over your equipment, or No. 14 welder's glass to wear over your eyes. Do NOT use standard sunglasses, UV or laser goggles, or any kind of homemade sun-shading contraption.
