Laser Light Safety Glasses Eye Protection Goggles Laser Protection Glasses Goggles OD 4+ Red Color For Typical 200~540nm Blue Violet Green Laser Engraving Cutting Machine

I bought this to protect my eye from blue light when working on the computer or using my phone later in the day. This can help improve sleep. The glasses work well for that and are wide enough to fit over my glasses.

They do work good work great with my laser print burner

Met expectations, replacement for a broken set from another manufacturer.

Bought a new laser engraver and wanted additional protection. These fit the bill. Comfortable and provide additional protection.

These work well with my 425 nm diode laser CNC machine.

Used to help me get tired at night while watching TV or using a phone. Genuinely blocks the vast majority of blue and green light. I can tell because they often just turn pitch black. Excellent purchase. Would purchase again.

Someone else mentioned scratches in their review, and I concur. I've never recieved a product before that looked like it had been used for 2 months beforehand. They also were supposed to arrive on a Thursday but the delivery date was changed and they came the following Monday. There were less expensive sellers with the exact same glasses that would have arrived at the same speed, so I feel I got hustled a bit. Fit is fine. They work the way they're supposed to. Just wish they weren't scratched up.

These red-lens protective glasses work nicely when using blue lasers. They are a bit difficult to see well with but they do protect the eyes.

Not worth the price
