got diff contact lens for diff eyeball "shape" one issit? cos i tried contact lens, wear not much problem, but take off is very difficult, like stuck on my eye like that. so i stopped wearing. the other day i went to another shop, i brought up to the boss, and he say is because they gave me wrong type of contact lens...
Yes ,there are different curves,diameters,materials eg Hema Copolymers,etafilcon A,senofilcon A ,galyfilcon to name some.
Some materials are smoother ,more slippery than some.eg vifilcon A and nelfilcon A which is used by Ciba Vision's monthly and dailies.That could be the reason why it's not easy to take out.
This Optical trade is a competitive trade,alot of BAD Mouthing each other...
The original optical shop may have given you the Ciba Vision's focus brand,which is good in its own right,it does not attract deposits easily..STAY CLEAN AND HEALTHY
