'WHATS THE DIFFERENCE BETWEEN O2 OPTIX & AIR OPTIX, WHICH IS BETTER?"

i usually directed them to another member's thread in kopitiam, but i would summarized it here.
both o2 optix & air optix are manufactured by ciba vision.

AIR OPTIX has the same material but with copolymer 845 to improve surface properties, to mousse foams and form clear, smooth-feeling, non-tacky films on lens surface.

air optix is aspheric design while o2 is spherical design.

aspheric lens offer thinner periphery thus less lens edge sensation, so better comfort. some said it offers better visual acuity but i personally did not feel any difference compared to spherical lens.

i tried both before, even with 1 piece o2 optix on 1 eye and air optix on another eye but honestly i cant feel any difference in terms of vision and comfort.
