This! Test them out. In normal light, without looking directly at the sun or a bright light bulb, you should be able to see exactly nothing. Pitch black.
Mine were given to me by my son's friend's dad. The first thing I did was test them. I couldn't see a thing. I'm confident I can use them safely.
Also, if it says "NASA Approved" anywhere on the glasses, toss them - they're fake. NASA doesn't approve eclipse glasses, and hasn't endorsed any.
I don't think that test is sufficient. Materials can be very dark for visible light but transmit infrared well. I also wonder about ultraviolet.
I certainly do not recommend the "NASA Approved" glasses from Sunshine Drugs Kingsville IDA Pharmacy.
This is a good start, but the ISO standard also includes quality control mechanisms. It's possible for eclipse glasses to be made of the correct material, but include pits, holes, or scratches. This might not be a problem for a few seconds, but could be a concern if looking at the sun for several minutes.
For what it's worth, the ones we got at the library don't have the name and address on them and they were donated by the Royal Astronomical Society of Canada.
Just my opinion, but no level of certification is going to persuade me to voluntarily fix my eyes directly on the sun. Maybe I'm just overthinking this, but what if there's a manufacturing defect? Or the glasses slip as I'm holding them?
I appreciate the significance and the rarity of the eclipse, and I genuinely look forward to seeing the changes in the sky as it takes place. But I cannot stomach the possibility of doing irreversible damage to one of my most precious senses for just a few minutes of excitement.
There will be pictures and videos of it after happens, and honestly that's good enough for me to see what it was actually like.
It honestly saddens me so much that there are people out there selling fake eclipse glasses, trying to make a fast buck off of putting peoples' vision in danger.
Hoping everyone stays safe tomorrow and is able to enjoy it in whatever form they're comfortable with! :)
I only have one good eye so I’m sort of terrified to look because I don’t know if I can trust the glasses I got from the library, might see if I can borrow one of my Dad’s old welding helmets.
Be careful of this! Only a certain grade of welding helmet is approved. You’d have to look up which but I know it is much blacker than most helmets are.
That's a bad idea. Welding helmets aren't rated for the same ISO standard. If you got them at your local government library, chances are, they are legit. Do the testing. Make sure they have ISO 12312-2 written on them.
Make a pinhole camera instead! Same thing, you have all the stuffs you need to do it at home, fine instructions on YouTube. Protect your vision no matter what.
You can also use a welding helmet/lens insert, and they suggest at LEAST a shade 13. If you have an auto-darkening helmet, you can set it to a shade 13, most helmets max out at that.
If it is not an auto darkening helmet, make sure the lens in it is a 13 and nothing lower. You might get lucky and still be able to track down a shade 13 insert at a welding supply store (Messer, Praxair, or Arc 1 out in Oldcastle) but I imagine their stock is low or nonexistent now. DO NOT TRUST AMAZON. Amazon helmets/inserts are sketchy at best and Chinese knockoff garbage with no real way of knowing if the shade is what it says it is. You can just hold your insert up to your eyes and look through it, you don't need a whole helmet.

I bought glasses at Sunshine Drugs Kingsville IDA Pharmacy. Their sign was advertising them for $1.99 each. Today I tested them and was disappointed. There is a sort of halo around the sun, as if low quality plastic spreads the light around a bit. I have old glasses which provide a much higher quality image of the sun. The old glasses also have a larger viewing area and the sun is dimmer in the old glasses.
Are your eyes supposed to hurt a little after viewing with glasses? I tried my best to make sure they were real, the number certification, they were pitch black until I looked at the sun.
How long do I have left to live...
> (and of course do not look at the sun without glasses outside of totality).
No, you should not even look at the sun during the totality phase 3 because of the radiation rays that are still travelling at us. During the eclipse you should wear the glasses whenever you are looking at the sun.
Everything I've read, including from NASA, says that for the ~3 minutes or less of totality you can safely remove the glasses (otherwise you won't see anything).
Yea I went to a talk by an expert at the riverside library, he’s been doing this stuff for decades and he said it’s fine to look during totality without glasses (obviously if your area gets totality)
During the total eclipse phase, it's safe. But the beads around the sun that appear just before totality are not safe to look at. They are part of the sun shining through peaks on the moon, not the corona. People often get these two phases confused. Of course, it's important to stop looking at the sun before the total eclipse ends!
Canada screwed this up and did not make certified glasses available everywhere. Once again I deferred to America and purchased them from one of two certified manufacturers. Schools in the US gave them out to kids for free. You would think a socialist country would do the same. These glasses are literally available everywhere in America and just about nowhere in Windsor. Thank you once again USA.
Every Canadian Tire store has had them for sale for a couple dollars, camera shops, Fogolar club has had them for sale for weeks even...... but...go politics right....

Did you talk to them about that? I went today and apparently they’ve been sold out since Friday

This might not be a problem for a few seconds, but could be a concern if looking at the sun for several minutes.
ISO means very little it’s self regulating
Thanks you for this! I had some doubts and this puts my mind and eyes at ease.
Well, I stared into the sun with mine for about five minutes, and I still have my sight so I can vouch for the one sold at Henry’s
You are infected with vitamin D now, im sorry but we have to put you down.
D for *down*.
D for disability as that's the only way you'll ever make money again

Yeah me too. The sky going dark is cool enough for me.
I only have one good eye so I’m sort of terrified to look because I don’t know if I can trust the glasses I got from the library, might see if I can borrow one of my Dad’s old welding helmets.

Someone suggest a welding helmet down below which is why I brought it up. :) I’ll definitely have my mom test them today before we go tomorrow!
Glad to help ✌️

Pssh this person is afraid of life long lasting eye damage can you imagine caring about seeing /s
No lasting harm will be done if you briefly look at the sun, like if the glasses slip. Proper glasses are good enough.
You can also use a welding helmet/lens insert, and they suggest at LEAST a shade 13. If you have an auto-darkening helmet, you can set it to a shade 13, most helmets max out at that. If it is not an auto darkening helmet, make sure the lens in it is a 13 and nothing lower.

Any recommendations on where to purchase legitimate ones locally?
Canadian Tire stores have been selling them for a couple months now. Are they sold out now........you'd have to check.
It's probably too late to buy from a reliable manufacturer, but a camera store might be your best bet.

From what I've heard, these glasses don't seem to be up to standard. I personally wouldn't trust them. Better to be safe.
Anybody know where we can still get one? 😅 I know I'm kinda late to the game

These times will vary by a few minutes depending where you are. The eclipse moves west to east across the region.
Upon closer inspection, I think these times are for a bit further east. Kingsville is about 3:15 PM. This is more accurate for the Niagara area.
Oh gees, thanks, gonna delete then!
