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

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

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

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

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.

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.

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.

I bought these to use at work but they were not company approved so I had to return them

I think my pair was used. They arrived packaged but dirty and scratched. I'll admit they are light. I don't know what "sheerness' is. The design is so bad it's uncomfortable to even put on. They're so dark it's hard to see the laser. I'm not familiar with them so perhaps that's necessary. Overall don't buy them if you plan on anything more than once in a blue moon use and don't spend more than$5-$8.
