There's plenty of scope for customization, but generally not in changing the shape of the cockpit.
Airliners are good at fitting 99%+ of the population well. But, in the end, airliner cockpits have switches and indicators up "high" and stuff down low that has to be easily within reach, but also not crowd your movement. There's a lot of adjustability, but adjustability (seat rails, etc) has been causes of accidents.
If you're within 5'2 to 6'3, odds are you can easily clamber in, fit, reach all the controls. That's all that's required. Even if you're outside of that range it might be OK (there is a 4'11 787 captain out there...)
As to glasses, there's no problem with having poor vision if it can be corrected with lenses. Aviation is not perfectly inclusive or accommodating of every disability, but it's not needlessly restrictive, either.
