These are some guidelines:

Visual Acuity:

Best Corrected in one eye of at least 20/40 with or without corrective lenses passes.

Less than 20/40 depends upon too many factors to list.

THE NEW LAW STATES: "The department shall not issue a driver's license to, or renew a driver's license of, any person whose best corrected visual acuity is 20/200 or worse in that person's better eye, as verified by an optometrist or ophthalmologist.  No person may use a bioptic telescope or similar lens to meet the 20/200 visual acuity standards." 

Bioptic Telescope Lenses are permitted for driving.
