I’m new to lasers and just recently bought a JTech 7W to use with my Shapeoko. The laser came with a pair of OD 2 goggles. I purchased a couple of extra pairs of goggles from Amazon. They claim to be OD 6+ with my laser. I was surprised that these goggles let in more visible light than the ones that came with the JTech laser, which is a good thing since it makes reading the LightBurn screen easier. I have not tried them yet with cutting because I have some concerns that since they are passing more visible light they might not be offering the protection they claim.
Has anyone here used these safety goggles?
