Bar laser show flash blinded me

A bar i was at last Thursday had one of those cheap light laser pointers and at one point one that seemed violet in color hit my eye. I remembered thinking it was painfully bright but not thinking more of it…

…until a day later I started seeing green splotches and now my vision is noticeably hazier (Sunday)
I don’t know when is the earliest I can be seen as I am traveling. Am I fucked or will my vision recover? I don’t even know if I can go to the bar and request they give me the details of their lasers - or how I could legally demand that.

*edit: I’m on the way to see an ophthalmologist now

Can't find seller of laser pointer. Help?

So, two years ago, I bought a laser pointer off of Temu. It's a really good class 1 laser pointer and has lasted me a while.

However, recently one part of it broke and I've been trying desperately to find, if not the same laser pointer, then a replacement part.

When I tried to find the seller in my Temu history, it said the seller was WAWYC. But when I tried to go to that laser pointer or go to that seller's page, neither are available anymore.

Does anyone know where I can look to fix or replace this laser pointer?

200mW 650nm (red) Sanwu laser can't ignite a match

I bought a 200mW 650nm (red) Sanwu laser (https://www.sanwulasers.com/product/304).

The description says that it can ignite a match, but I have tested it and I cannot ignite a match. The laser has an adjustable focus, and I am using it as focused as possible. Is something wrong with my laser?
