Woud you care to tell us where you got your information from, alecchong?[/quote]

hello, i just want to claim that "i've never learned these information of the wearing from internet!"

----all i learned from the real life, from the officials of bausch & lomb and johnson & johnson in some different countries!

i was born in china, now studying in college in malaysia.

i began to wear contact lens when i was in senior middle school in china. soon i became very interested in contact lens, i collected some information from professional books, advertisements of the lens companies, eye doctors , opticians and so on.

i first noticed the wearing period is different is the year 2003. than time in taiwan, b & l employed a local pop team s.h.e to advertise. i noticed that soflens 59, in taiwan, is recomended to use for two weeks, at the same time, in china mainland, SofLens 59 is recomended to use in one month! i continued to check the official website of b & l in taiwan and china, later found that not only soflens 59, but SofLens 66, toric, soflens 38, and sequence, the wearing period is all different, generally, in china is two times longer than taiwan.

later i fonud not only b & l, but also j & j, j & j's acuvue, in china is recomended to use for one month, but in other rich countries is only two weeks!

for this i called the official customer service line of both b & l and j & j, both of them gave the same explanation: we don't care how long the wearing period in other countries, we have already done enough medical experiment in china that to wear for one month won't damage your eyes.

yeah, their standar in china is only "won't damage your eyes"!

later i had travelled to hong kong for times, i went to ask some professional opticians there, found that the wearing period there is the same as in taiwan and us, almost only half of it in china.

in 2006 i came to malaysia to study in college, i found that in malaysia, soflens 56 and 66 toric is also recomended to use for one month, the same as china. but soflens 38 here is recomended to use for one or three months, different from china, in china is six months!

since malaysia is also a developing country, but a bit richer than china, not as rich as its neighbour singapore and other westen countries.


the most funny is that, in singapore, soflens 56 and 66 toric is recomended to use for two weeks. as we know, singapore is quite near malaysia, it takes only 1-4 hours to drive to some main cities of malaysia. and the climate, the air environment, and the people's living habbit is almost the same in the two countries, then why b & l recomends the different wearing period in the two coutries? -----although the climate, the air environment, and the people's living habbit is almost the same , the average income is different!!!

generally, i find out a rule of theses lens companies, especially b & l, its wearing period in each country is not based on the consummers' eyes, but their income!

their standard in rich countries is "to be most comfort", but in poorer countries is "won't damage eyes"!!!!
