As has been stated, stereo vision falls off at 50ft.
There is evidence that beyond 50ft the brain works hard at identifing the roundness of subjects to provide a faux stereoscopic vision, let's call it a perception of depth.
I understand that persons who have lost their sight in one eye have developed a greater skill in this regard.
Perhaps this is also the case with people with your condition?
If so, your arguement is that you have better depth perception beyond 50ft than the rest of us.
