Contact Lens Prescriptions vs. Eyeglass Prescriptions
A contact lens prescription is very different than an eyeglass prescription. In addition to the lens power, your contact lens prescription contains several other pieces of information related to the size of the lens. These will include base curve, diameter, power, and experation date. Toric and bifocal contact lenses also contain more numbers specific to those types of lenses.
