Wrap-around sports glasses need different sizing than regular frames. The curved design changes how measurements translate to fit.
For wrap-around sports glasses, I use larger measurements than my regular frames. My sports glasses are 60-15-130 compared to my regular 52-18-140. The wider lens and shorter temple work with the curved design.
The wrap-around curve means the frames sit closer to my face. The 60mm lens width provides coverage without the lenses being too far from my eyes. The 15mm bridge works because of the curved design.
Wrap-around frames use shorter temples - 130mm instead of my usual 140mm. The curved design means they reach my ears sooner. Longer temples would extend too far past my ears.
Secure, protective sports glasses that stay in place during intense activity. The specialized sizing provides coverage and stability that regular frame measurements can't achieve.
