I wasn’t sure what to get when I got my laser and settled on these…
No idea if they are better or not than the ones you picked. But these have worked good for me. They are darker than they look in the pic and have worked great for my diode lasers
From what i saw. It highly depends on the laser you are using as to what color you buy. I am not sure but i think there is no DEFAULT pair of goggles that work for everything.
I have installed a neje a40640, according to what I see in the specs it is 450nm.
Here are the glasses I use for my NEJE 40640: https://www.amazon.com/gp/product/B08R4PMCHR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Not that I know what these certifications mean, but I purchased them because of this statement: “Certifications：EN207: 1998 + A1EN207: 1998 + A1: 2002 approved.” I figured that anything that was verified by a third party was likely better than random stuff out of China.
