I was using the cheap laser safety glasses that came with my laser engraver. Once I tried this new pair of glasses on I would never again use cheap laser safety glasses. These are very comfortable and I can check engraving status without any eye discomfort. You only have 1 pair of eyes and if you're looking to save money, cheap laser eye protection should never be considered. These glasses are high quality and I would absolutely recommend them.

using this with a laser they seem good. i can still see. i use them to look at refracted laser light. i dont take any needless risks.

Let's just say hypothetically someone tried to shine a laser pointer at your face. They might use a green laser, with a wavelength of 532nm. You would see it dancing around in your field of vision, so you might be able to close your eyes or turn your head in time to avoid retina damage, but it sure would help to be able to block it at least partially. But what you may not know is that many green lasers also pass 1064nm wavelength light, which is infrared. You could be staring right at it and not realize it until the damage is done. That is, unless you had a way to block both wavelengths at the same time. In a different, strictly hypothetical situation, someone might point a more standard 850nm or 940nm light or laser at your face. It sure would be great to get at least partial protection from all of the above, at an affordable price. Even better if they fit over corrective lenses.

Hace poco invertí en una ND YAG Q SWITCHED y trajo unas gafas terribles, me imposibilitaban la visibilidad de los tatuajes que estaba removiendo con mi láser.
Estas gafas han sido un éxito total, no veo el resplandor del láser y mis ojos se sienten muchísimo mejor desde que las uso. Son muy fuertes y tienen la cobertura a los lados.
Recomendadas al 100%.

Great
