Remarkable Features 1. Heat-resistance　　 up to 120℃ without any crack

2. Deformation-resistance　　 No Crack at 100kg with the pressure by Edger Machine　　　　　　　　 Crack-Free

3. Scratch-resistance　　 Enough strength against scratch, hard to recognize tiny scratch

(by Wire-brush) ○ △*1 Crack occur at 100℃ even after edging. However, due to the deformation of Lens itself, the correct power cannot be measured. Therefore, we would say this temperature.

What is the benefit? (for Consumer)

Resistance to Heat, Scratch, Dirt (Stain)In the car （ about 80℃ ）Barbecue, Cocking (reflective heat, smoke, oil)

Beach in Summer (reflective heat, sand, sea water)

Less Crack, Scratch on tough occasion　 on “careless”, “accidental” occasion

　　　　　　 Safety! Comfort! Durability! 　　　　　　

Resistance to Heat, Pressure, Scratch　　 too much pressure by chucking (deformation, pressure)　　 edging for plastic frame (heat, deformation)　　 handling procedure (unintentional scratch)

　 reduce the loss on edging occasion　 release from “complaint against Crack, Scratch”

　　　　 Increase Customer Satisfaction!
