In reply to the discussion: Amazon, don't refund my money, send me the right eclipse viewing glasses! You have 1 week to do it. [View all]Ms. Toad
(34,060 posts)41. Please stop implying the very dangerous practice you have apparently been engaging in
is safe ("my eyes lied" .
Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun; they transmit thousands of times too much sunlight. https://eclipse2017.nasa.gov/safety
Why is it so dangerous to look at the eclipse without glasses?
Van Gelder notes that anyone who's taken a magnifying glass out on a sunny day to burn holes in leaves has seen how powerful the sun's rays are. When we look directly at the sun, the part of our eye that is in danger is the retina, a light-sensitive layer that can easily be damaged by high levels of light.
"There are not pain fibers in the back of the eye, unlike our skin. We have a natural aversion to staring at the sun, but it's possible to overcome that by force of will," Van Gelder said.
Looking directly at the sun can cause temporary or permanent damage to the retinas. The most dangerous time during an eclipse is when the sun is not fully blocked by the moon, during what's known as a partial solar eclipse. Many parts of the country will only see a partial solar eclipse, and even the parts that will see a total solar eclipse will see a partial eclipse before and after totality. Anyone viewing a partial solar eclipse should use protective eyewear the entire time they're watching.

If you have, indeed, viewed the sun directly with your dark sunglasses, and not damaged your eyes you are very lucky. Don't count on that luck continuint.

It isn't the dealer you have to worry about, but the manufacturer.. Amazon sold real ones too, but

Ask for a refund. Glasses at that price should be better, even if prescription,

and a seeing eye dog if you do. Simple polarized sunglasses are NOT sufficiently protective

My sun glasses are very dark, I have looked directly at the Sun with them on.

A person would have to be an idiot to stare at the Sun for more than about 10 seconds.

You might be the only one who posts in threads about things he doesn't care about.
