How can you calculate visual acuity based on eyeglass prescription?

In brief: Simplistic

The simplistic answer is that a good optometrist/ophthalmologist knows what acuity corresponds with what prescription.
I don't think you will find a formula to calculate this.

There is not a good correspondance between the eyeglass prescription and the Snellen (like 20/20) acuity. These are on independent scales with only the loosest correspondence.
