I work for Ocutech - we make bioptics :) . Ours are the leading bioptics used for driving so feel free to ask me any questions.
$1 The low vision specialist that I work for, Dr. Greene, was the first optometrist to be on the NC DMV medical review board and helped create the bioptic driving laws for our state. NC passed our law in 2014 and it has been a miracle for so many people that thought they couldn't drive. Every state is different though, but we have great contacts all over the US that can help with specific bioptic driving - let me know if I can help you in any way!
