Personally, as you are nearsighted, I think you can fill your self of a normal pair of glasses suitable for sports. The glasses should have frame as the screws of glasses without frame are easy to become flexible and this can make you suffer from injury. And the best frame should be titanium alloy with good formability, and it is better with wide frame. Second, the lenses should be hard resin lens. Hope this will help you!
