Yes, you need to focus on glasses that don’t have excessively curved lenses, as this can get very expensive, or even impossible. And also you are usually better off with a full rim around the lenses, not half lenses. Esp. if your lenses are on the thicker side. I had my Adidas and Nike glasses turned into prescription. They were however a lot more expensive than the Ryders. I would pick out the glasses at an optometrist, so that they can advise if the lenses can be replaced with prescription lenses. Good luck!
