Can you tell me the minimum vision acuity?

Acuity: I am guessing that you want to know the minimum acuity for various legal categories. In most states, 20/40 is required in the best eye for a driver's license. In most states 20/30 in both eyes is required for a commercial license. 20/200 is the limit of legal blindness. The level for obtaining benefits for blindness varies from state to state and there are federal standards also.

Clarify the question: Minimum acuity for what purpose? Driving? Reading? Or the best possible acuity? I.e. 20/10.
