Have you tried contacts?
I've got issues with depth perception. But it seems to be better with the contacts than with my glasses.
Just a thought.
Your mileage (and distanct from the other vehicle) may vary.
Tried contacts...if my eyes are corrected equally, I see double.
From what I've read, your ability to see depth is formed pretty early. Since I all but lost the sight in my left eye as a baby, my brain never learned how to put stereo images together.
Most of the time, I just deal with it. But night driving scares me, and I have to be pretty careful in some other situations.
*sigh*
But I'm going to #1 Nephew's 3rd birthday later... so that will be nice.
