This new model from grow glasses experts Method Seven is the best buy for working under high pressure sodium lights both indoors and outdoors. 

They feature German mineral glass from the Carl Zeiss laboratory impregnated with exceptional minerals that manage to filter the spectrum of greenhouse light, so you can see true colors and detect any marks or imperfections. 

Scratch resistant, quick to clean, perfect HPS+ color, they block UV light and infrared heat, and they also allow you to use your mobile phone or other screens thanks to their cutting-edge light and color filtering technology.
