Nice glasses for welding etc. a little pricy

Muy bien el producto le entrega rápido sí les recomiendo el material de los lentes son tipo plástico semi flexible calidad buena

They work great, but the inserts / powered areas is a little bit to high which makes them enter your area of sight just a little bit too much.

The optics in these glasses are poor. The 2 x has some kind of flaw. The glasses make me feel dizzy. I wear glasses on a regular basis but there is something wrong with these! Don't buy them. But now worse Fastmedia will not accept them back without me paying for return shipping. It costs $25 to return a $50 item. I'm getting nowhere with Fastmedia. Don't buy from them if you think you may have to return an item. There response is useless.
