Eye doctor prescribed Biofinity Toric Contact Lenses, Can I replace them with a different brand.?
such as PureVision Toric or anything cheaper.
Technically you are not allowed to just choose any contact lens that you want if your doctor prescribed a particular lens. Law requires that any lens you end up ordering must be approved by the doctor. The reason for this is that each lens may fit differently on your eye. If you end up choosing a lens that doesn't fit properly, not only will it be uncomfortable, it can cause harm to your eyes as well. Although they may charge you, you should talk to your doctor and tell him/her it's too expensive and you want a cheaper option..
