Hello. I am wearing O2 Optics which I understand are extended wear lenses. I only wear in the day for around 12 hours, not overnight. As they're extended wear I thought I'd be able to wear them maybe 6 days a week, so why does my optician say I should only wear them 5 days a week?
I think they are great. I switched from dailies because they were pretty drying. I'd recommend them to anyone having the same problem.
