How to tell if your total solar eclipse glasses are legit


"Your eyes will be damaged by the eclipse", explains Covenant Health Plainview ophthalmologist, Douglas Kopp, MD.

"It creates a chemical reaction with the retina and burns it", he said. The eclipse will begin around 1 p.m. Monday, reach its peak about 2:30 p.m. and will be complete before 4 p.m. Its magnitude will be 79.5 percent with maximum area obscured at 74.77 percent. They are made to filter out 99 percent of visible light, as well as harmful infrared and ultraviolet rays from the sun. But the next total solar eclipse won't hit Northern California until 2045 (giving us a much better view then), so for some it might be worth the trek.

Alas, Louisiana lies outside the path of totality, and people here will only be able to see a partial eclipse. For this reason, they must be worn at all times during the eclipse. Your vision may be distorted and you could develop blind spots.

The Moon is tilted 5 degrees off earth's orbital plane, meaning the the moon's shadow rarely hits the Earth's surface and that is why solar eclipses are so rare. One popular way to see the partial eclipse is to indirectly view it through a pinhole projector. But any individual location will only experience a total eclipse once every 400 years, which is what makes this coming Monday such a special occasion.

The class has been preparing for the solar eclipse, and 3rd grader Daniel Johnson says he's ready for it. The telephoto lens and solar filter will help, but the quality may still be lackluster. Lens must meet a very specific worldwide standard known as ISO 12312-2.

There are a few retail stores NASA recommends that carry eclipse glasses and filters, but by now they might be sold out, especially if you don't live in the path of totality.

Various cities and towns in these states will experience periods of complete darkness during daytime hours as the moon passes in front of the sun, blocking any possible sunlight.
