Are Glasses and Contact Lens Prescriptions Different?

The short answer: yes! Most of the time, the actual numbers in your glasses prescription need to be converted to account for the reduced distance between your eye and the corrective lens in contacts. In addition to this, not all contact lenses fit the eye the same, so your contact lens prescription will always include an actual brand and base curve of a specific contact lens, which a glasses prescription won’t have. The only way to get an official contact lens prescription is to have your optometrist fit you in a specific set of contacts and do all the necessary conversions for you.
