Millions of people in parts of Eastern and Atlantic Canada will be able to see the rare solar eclipse happening on April 8. But they should only look up if they have proper eye protection, experts say...
The eclipse is more dangerous actually… The visible light is reduced so your pupil expands. But a lot of UV light comes from the corona of the sun which isn’t blocked during the eclipse. So your pupils are more open allowing in more of the harmful UV light. And to add to it, your eyes don’t realize they are being harmed by UV light without the visible so you don’t have that impulse to look away.
this is incidentally why you should never buy those $.99 sunglasses. Any sunglasses that don’t actually have a uv filter are gonna mess your eyes up and who knows with those cheap ones
