PC Optical Lens
PC lens. Light: The weight of these lenses is lighter than that of traditional glass lenses by 57% , lighter than traditional resin lenses by 37% , hense they reduce the pressure over the wearer. Safe: Compared in terms of collision resistance, PC lenses are 10 times stronger than common resin lenses, 60 times stronger than glass lenses. In addition, PC lenses are more suitable for the assembly of the frame with thread and hole. Healthy: PC material is anti-ultraviolet light itself, the lenses are capable of segregating 100% of maleficent ultraviolet light, so capable of prevent the eye illnesses such as cataract and crystalloid aging in the eyeball, and etc. Clear: The transmittance of the lenses is higher than of glass lenses, so clearer vision. Similarly, the chromatic dispersion of high quality PC lenses is less, so more acute and clearer, and the lenses of the same degree can rectify your vision better. Color: The lenses can be dyed on demand. They can be dyed dark, serving as sunglasses with power, and they can also be dyed various light colors for decoration purposes.
