I have seen him twice over recent years for four pairs of progressive multifocal spectacles. He tailored them all to my requirements for flying. They were awesome each time. He really takes the time to check the distances and width of the centre field of each part of the lens to best meet your specific needs.
I am sure that he could help you.
