best and cheapest way to go is use daily wear contacts.
(the ones meant to be thrown away each night)
Been doing this for years, eye doc says no problemo.
I take them out each nite but wear them for a week. Fresh pair on Monday morning
and in trash on the following Sunday.
If you compare the formula for daily wear and weekly wear. they say the exact same thing, atleast for the brand i am using (1 Day Acuvue Moist)
taken from the website...first is 1day acuvue..2nd is the weekly wear Acuvue
Etafilcon A. 42%
Etafilcon A. 42%
same thing. buying the daily ones works out to about 2bux a week.
