What Is A Contact Lens Prescription?
A contact lens prescription consists of many different calculations which not only involves a prescription, but also lens materials, which can affect the health of your eyes.
A contact lens prescription is not the same as a prescription for glasses! In addition to the optical correction of the eye, a contact lens prescription contains detailed information about the design features of the contact lenses, including the specific lens material and fitting parameters. The ultimate goal is for the contact lens wearer to see well, be comfortable, and not harm his/her eyes by wearing the lenses.
The important differences in a contact lens prescription can only be determined through special measurements and evaluation of the eyes for contact lenses. The testing necessary to determine a contact lens prescription is not done as part of a routine eye examination. A thorough diagnostic fitting with contact lenses on the eyes and appropriate follow-up evaluations to determine that the prescribed lenses are optimal for the patient, are required before a contact lens prescription can be finalized. With some patients, lens design modifications may be needed before the practitioner can arrive at a final contact lens prescription.
We hope that this short explanation will help you understand why a spectacle prescription is not the same as a contact lens prescription. If you have any questions, please feel free to ask our staff.
