Hi Josh,
Are the aviators name brand or generic? This can make a huge difference when answering this question. Typically, name brand glasses come with screws that are already tightened, but can also be adjusted (provided you have the correct screwdriver) as wear and tear occurs. Some off-brand glasses come with fixed screws that can’t be adjusted or will strip if tightened or loosened. Let me know which kind you have and I might have a better solution for you.
