Noob goggles question

I ordered these from o-like

405nm,450nm,473nm,532nm laser safety goggles [OLGLG532] - $19.99 : Zen Cart!, The Art of E-commerce

Did I waste my money or are they of some use?

Thanks,
Tom

They are legit.
The reason they're low-priced isn't the glass-material, but the material surroundingthe glasses (plus supply, design etc.).

You can get them even cheaper a eBay, but it's up to you wether to buy these particular goggles
