Surface treatment to maintain moisture

Plasma treated to improve wettability and to prevent dirt and clouding while sustaining moisture.

RGP contact lenses are similiar in size than soft contact lenses, which enables tear replacement and more oxygen delivery.

Clear vision

Optical design less susceptible to blurring

The front surface utilizes an aspheric design to correct blur. Clear vision is obtained because focus is less likely to blur when the wearer blinks.
