Same experience as other reviewers on here. I've worn contacts since 1971. First hard, then semi rigid gas perms, and then soft. I've worn Accuview Air Optix Aquas for many years, but about a year ago they started lasting sometimes a day, maybe two, maybe a week if I'm lucky. I started running through boxes like crazy. They used to last for months -I would change them out as a matter of protocol, not defect. I get them from Coasatal and about the same time as the box changed, the quality went down. I called and got a credit for two boxes immediately, but this keeps happening. I know what you're thinking, like me you think it's you; something you're doing, it's not. They have changed these and it's not good. Alcon has ruined a great product.
