Consequently, they require distinct prescriptions for optimal vision correction, meaning you can't automatically transfer your glasses prescription to contacts.
While your current glasses prescription may serve as an initial guide, it doesn't replace the need for a dedicated contact lens consultation. This process will outline specifics such as the base curve and diameter of the lenses, the material or brand type, and the expected duration of use before needing replacement.
