Lol sorry this is like my 3rd question in this section in the past 2 days
  Anyway I was looking through contact lenses online stores and found they have a fixed diameter
  I haven't taken the contact lenses fitting exam yet so I don't know my diameter. But does that mean the diameter doesn't matter?
  I also found that there is a fixed diameter per brand.So does that mean as long as I know my base curve and it's available for the brand I want does the diameter matter?
  thanks
  Added (1). Does the eye doctor choose what brand lenses you get or do you get to choose? I want monthly disposable because I can't afford others. WIll this be a problem?
