Is that enough? I hate companies that hold people's health so cheap.  And I feel lucky that my Rx is Focus Night & Day.
Update: I've found out that CIBA Vision China recommends 1-month replacement for O2Optix, in the US it's 2 weeks. So I won't have any contact lens to wear if I decide to boycott these companies.  |
yeah, b & l do this in many poorer countries!
but i just want to tell you, j & j's acuvue is different from acuvue clear.
you can easily find the info of acuvue in j & j's official website, it's the word's first disapossible lens. its central thickness is only 0.07 mm, oxygen factor is 40 dk/t.
acuvue clear, maybe not sold in us, the central thickness is 0.105 mm. oxygen factor is 28 dk/t, is quite similar to j & j's discontinued lens survue, since it's a bit thicker than acuvue, so it's easier to hold on, is suggested to first time users, and its price is also lower.
acuvue and acuvue clear is both sold in china. since acuvue clear is not sold in us, we can not compare. but it's a fact than j & j make the wearing period to one month in china, in us only two weeks.
last, ciba vision o2 optix, in its us web site it says the wearing period can be two weeks or one month, depend on the custmers' opticians' suggestion.
