high quality metal 3d optical glasses:
Top grade metal frame,optical resin lens

high quality metal 3d optical glasses:

1) Lens material: Imported acrylic lens

2)Optical parameter: Polarized efficiency 99.5%,transmittance 43.5%

3)Compensate parameter: *125nm/138nm

4)Whole qualit grade: *A+

5)Physics Parameter: Legs can anti-bending,anti-high temperature 110 degree,anti-cold -22 degree,protect from bending.

Attention:

Lens can’t touch water or some liquid which are easy melt with water,whole glasses can’t be cleaning by ultrasonic wave or liquid. We suggest antisepsis with ultraviolet radiation,30w or 40w power,irradiation intensity is 70uw/cm2 or above,antisepsis time should be 30min-60min.
