Is 20/400 in both eyes better or worse than 20/200? I am trying to determine if I am considered legally blind using the following definition "if your vision cannot be corrected to better than 20/200 in your better eye, or if your visual field is 20 degree

In brief: Worse

20/400 is worse than 20/200.
Legal blindness is the vision with the best glasses possible. The term is used incorrectly often (as in "i am legally blind without my glasses").

The vision scale works like this.
Consider the first number to be x and the second to be y. When you are looking at something x feet away, you are able to discern it as though it is at y feet away. So with 20/400 vision. You see an object at 20 feet away as well as someone with good vision can see something 400 feet away. So, 20/400 is worse than 20/200.
