How high or low is the refractive error in a contact lens?
3 doctors weighed in across 2 answers
Depends on the brand: On average, can range from minus 20 to plus 10 in quarter or half diopter steps. Depends on soft vs. Hard contact lens, astigmatism correction, etc. Plus custom lenses can be made.

For almost all: Contact lenses are available to correct almost every refractive error, including various levels of myopia, hyperopia, and astigmatism.
