We have been fitting disposable lenses since they were invented over 20 years ago.
These day's they account for practically all the contact lenses we fit (for an idea of our fee structure click here)

The benefits of frequent replacement are well known

Basically we fit 3 types of lens:
2 weekly, monthly and daily replacement

If you require regular wear 6-7 days a week with long wearing times maybe 15 -17 hours average I recommend 2 weekly lenses like Acuvue 2 or Acuvue Advance

If you require regular wear 6-7 days a week with wearing times up to 12 - 14 hours average I normally recommend monthly replacement lenses

If you require irregular wear so the lenses are worn some day's and not others I'd always recommend 1 day lenses
