Amazon recalls solar eclipse glasses

Kathy McNeilly, second from right, director of the Oak Ridge Public Library, and library employees presented a pair of solar eclipse glasses to City Manager Mark Watson, center, on Thursday, Aug. 10, 2017. Special eclipse shades will be available. Normal sunglasses don't provide enough protection.

According to NASA's total solar eclipse interactive map, Ferndale will see a partial solar eclipse - 87.39 percent of the sun will be obscured by the moon.

The lenses of some obvious fakes allow the penetration of light from such relatively faint sources as fluorescent lamps, while the only thing one should see through authentic solar-safe filters when looking at objects fainter than the sun is pitch blackness.

The American Astronomical Society has listed manufacturers of eclipse glasses on their site, which are verified to be compliant with the ISO 12312-2 global safety standard. If it is scratched or damaged, throw it away.

Amazon recently sent out an email to customers to let them know some of the solar eclipse glasses they have been selling were not confirmed safe for viewing the eclipse. The optical device concentrates the sun's light, which can damage the solar viewer and then your eyes.

If you normally wear eyeglasses, put the eclipse-viewing glasses over them or hold the hand-held solar viewer in front of them.
