Department of Motor Vehicle Visual Requirements (DMV)
You should check this by calling the DMV in your State. They do change over time. Almost all other States 20/40 or better. (In the better eye, or both eyes together). I always check my own eyes with my Snellen, and would not drive a car if I did not pass the 20/40 line (and much better). My current Snellen reads 20/20. I always go to an ophthalmologist for pure medical checks, but if my refractive state is slightly negative, and Snellen 20/30, I will work with the preventive plus, until I get to 20/25 or better. Use your own judgment here.

You should have your own Snellen up on the wall. Here is one for free.

I restrict what I advocate, to persons who can still read the 20/40 to 20/60 line. Here is a person who got the, “correct concept”, and was successful.

The optometrist will never supply your P.D. If you buy On-Line – here is a description of what it is, and how to fit it. I am an independent engineer, and prefer to make these measurements myself. This includes self-checking my PD and refractive status. Here are the details.
Enjoy,
