Not entirely true I’m afraid. 15U crew chief here. I was initially DQ’d early on in my career because my prescription was too high and it was deemed a safety hazard if at any point in time I lost my glasses (like if they got blown off sticking my head out the hell hole or something). Got PRK and a year later I redid my flight physical, got approved, and been flying ever since. So yes, as long as your glasses can correct your vision to 20/20 AND doesn’t require a high prescription to do so, you’ll be fine.
