Q: 1 box for each eye
A: I wear the acuvue oasis contacts and have been wearing contacts for the past 8 years. I have always been told to change my contacts every 2 weeks. So in theory, 1 box of 6 lenses would last you 3 changes aka 6 weeks. If you have one box for each eye, it should last you 12 weeks or 3 months. I just looked on my boxes, and it doesn't say anywhere on there how long to wear them. The best thing you can do is call your eye doctor and just ask. However, I've worn acuvue for years and always been told to throw mine out after 2 weeks if thats of any help.
