Default how can acuvue and acuvue-2 be worn over night?
the oxygen factor of Acuvue is 40 dk/t, acuvue-2 is 33 dk/t.


but if the lens can be worn over night, its oxygen factor must reach at least 100 dk/t.

so i'm puzzled why acuvue and acuvue-2 can be continious worn for one week.

i tried to wear acuvue for only once over night, but it was very uncomfortable, and in the second day my eye felt very dry.

i also tried to wear focus night & day over night, it was much better than acuvue.
