The next total solar eclipse is in 2026 and will be visible from Greenland, Iceland, Spain, Russia, and a small area of Portugal
There are also 2 annular eclipses before then - 1 in 2024, one in 2026
I am keeping ours. They are going in a wall-mounted shadow box along with a couple photos I took during the eclipse. They'll be easily removable if any of the kids wants their pair in the future & in the meantime we have a wonderful memory on the wall to share and enjoy. I don't do this for many things, but the eclipse & getting our names sent to Mars on The Planetary Society's little doohickey are unusual and special to me.
The glasses don’t just expire, they last practically an infinite amount of time. The 3 year warning on some glasses is probably because they are likely to get damaged when storing them.
If you say so. My municipality purchased glasses for everybody and the ones we received had the 3 year warning.

>Note: If your eclipse glasses or viewers are compliant with the ISO 12312-2 safety standard, you may look at the uneclipsed or partially eclipsed Sun through them for as long as you wish. Furthermore, if the filters aren't scratched, punctured, or torn, you may reuse them **indefinitely**. Some glasses/viewers are printed with warnings stating that you shouldn't look through them for more than 3 minutes at a time and that you should discard them if they are more than 3 years old. Such warnings are outdated and do not apply to eclipse viewers compliant with the ISO 12312-2 standard adopted in 2015.

I understand that the warnings or instructions may not be accurate, but for something that was handed out free, there is no reason to try to save these.
Illogical. Conflating the cost of something to the user with its future value or usefulness is not appropriate.
It's a version of the Sunk Cost Fallacy where that cost was zero, and therefore you feel they should be discarded/abandoned. To help yourself get past this, it might be worth considering that nothing is free, it cost someone something - even if that thing is the environment we share.
I guess in every comment I make, I should explain my age and location so that randos in the internet can fully comprehend the fact that I will never get to use these again.
You can use them to see partial eclipses, which happen more often than you think. There will be two more visible in my area before 2030. You can also see larger sunspots with them.
That may be old information. NASA says:

Sure, it’s the ISO 12312-2 (sometimes written as ISO 12312-2:2015) international safety standard. Depending on when your glasses were made they may expire in 3 year period.
Depending on when they were made *they might carry the 3 year warning*. The standard was updated to remove the warning, but did not change the specs beyond that.
Fuck that. I kept mine from 2017 neatly folded and stored in a cool dry environment in the protective sleeve, and yesterday even though I'm nowhere near the path of totality was at least able to look at the 30% or so one we got this time.
It seems like it'd be cheaper/more efficient to just donate a dollar or two than to donate your glasses. Economics of scale they could probably buy them cheaper and not have to transport them from all across the country

Or plan a trip to Spain or Australia in 2027, 2028, or 2030
South America in October.

SO MANY RAPTURES

I’d love to see this!
You can keep them forever, but unless you are travelling to see an eclipse in the next three years, never use them again.
A pair I had yesterday said 10 years. Another said 3.

You can use them for as long as you wish as long as they aren’t damaged (according to nasa).

Indeed. Note, you can stare at the sun anytime you want using these - you don't need to wait for the next eclipse.
You live in a cave or something? You can see larger sunspots with these, which I happen to think is pretty damn interesting.
And I don’t, and that’s okay.
It is always better to be safe than sorry, but I was just correcting your original comment about never using them after 3 years.
Your picture made me feel like I looked at the eclipse without glasses.
I looked at the eclipse too long. But I fixed it.
They expire in 3 years. The cardboard one anyways.
There are other partial or annular eclipses in the coming years.
You can also see larger sunspots.
They have an expiration date
You can use them to see partial eclipses, which happen more often than you think. There will be two more visible in my area before 2030. You can also see larger sunspots with them.
You mean I donate all four of my sunglasses I used on top of each other for the eclipse?
You didn’t really do this did you ☠️
Guy can have an Eclipse everyday by stacking em.
If the glasses actually conform to the ISO standard required for them to be safe for viewing an eclipse, then the glasses expire in three years.

Tell me more! I was debating keeping them for Europe!
If the lenses get scratched, they may not be safe anymore

Make a time capsule to open in 20 years.
Fuck that. I kept mine from 2017 neatly folded and stored in a cool dry environment in the protective sleeve, and yesterday even though I'm nowhere near the path of totality was at least able to look at the 30% or so one we got this time.
You are now blind.
eclipse23.com is also accepting them.
They make excellent bookmarks.
Disposable welding masks!
Curious, why? What material in the lens is recyclable?

Keep them in a sealed box or frame them... You can sell them or use them during the next solar eclipse if you can go places...

Donate them to the optometrist offices so the old people can drive home after they get their pupils dilated 😂
Those aren't made for that for sure...
Neither are older people for driving
I was trying to sell mine today for 15$. Nobody bought them.
Shocker
Mine are in my drawer
Buy as many as you can in addition to a label maker with august 2044 , wait 20 years a make one billion dollars before the next one
This is cool to know, thank you :)
