Yes: It is due to a differing vertex distance or where the corrective lens is placed in relationship to the corneal surface - this is normal.

A small difference : Is normal. A significant difference would be unusual but it could just be the way it is written in a different format.

Distance from cornea: Contacts sit directly on the cornea so their magnification power is different than lenses in glasses that are in front of the cornea.

A 42-year-old member asked:
What would you suggest I do to convert my glasses prescription to contact lens prescription?

Slightly tricky: Mostly straightforward if there is no astigmatism but a little involved if there is astigmatism. I assume you are ordering lenses online and will need that conversion. There is also some experience functions depending upon the type of lens. Check with your ophthalmologist to get this done for you. Optometrists are unlikely to do it as they prefer to sell you lenses.
