Kunze Land Goggles

Ventilation design is more intimate; The U-shaped nose support is more antiskid; Antifogging coating technology is adopted. A special protective film coating is formed on the surface of the glasses to make the lens have anti fog function, and the surface of the lens is more bright, effectively reducing the influence of fog on the line of sight in daily work. UV protection; In the electromagnetic spectrum of ultraviolet radiation, the wavelength ranges from 10nm to 400nm. PC material can absorb ultraviolet light with wavelength below 400nm, but it will not block other visible / invisible light. The transmittance is 91%, and the UV ultraviolet reaches 99%, almost completely filtering ultraviolet light. PC lens has stable material performance, high price and complex manufacturing process; Many manufacturers choose PVC material instead. PVC material has low stability, fragile lens, poor impact resistance, poor light transmission effect, and will produce toxic volatiles in case of high temperature and high heat, which is harmful to human health.
