Hi, soft contact lens cant reduce short or long sightedness. Only semi rigid lens can do that.

If plan to wear more than 12 hours per day, then try purevision 2, air optix, night & day. Thanks

hi, there are more lenses in market now which u can wear for more than 12 hours a day, which means u can even sleep with the lens on, but of course i dont recommend u to do that.

Purevision
Purevision 2
Air optix
O2 optix
Biofinity
Night & day

hi, how many hour per day u plan to wear the lens without taking out? Does ur occupation required u to have clear vision at all time?

purevision is hard, purevision 2 better. Both has HD vision.

air optix and o2 optix can have different vision even though same power, ciba vision sucks at solving their optic problem.

night & day is usually for those plan to wear 30 day & night without taking out, they have problem handling lens.

biofinity is ok, I waiting for more feedbacks too.

I guess u can try air optix, O2 optix, purevision 2 and biofinity. As we not sure which will suits u the best, I suggest u to buy 1 pair each to try out 1st. Pls pm me if u interested to do that, thanks
