Do you like glass and resin lenses

The Pink Tortoise Glasses lens has stable refractive index, good wear Rainbow Eyeglass Frame resistance and stable optical properties, but it is heavy and easy to crack. Glass lens: stable refractive index, good wear resistance, stable optical properties, but relatively heavy, easy to crack. Resin lens (CR-39) : Warner Sunglasses light, safe, high transmittance, not easy to crack, but easy to wear surface. PC lens: high refractive index, strong, but easy to wear surface. Reduce the lens degree (generally between 1.00D ~ 3.00D), strive to maintain comfort and binocular vision function. Use the lowest degree lens that can also correct myopia to the best vision. After fitting, it is recommended to try on the glasses for a longer time, so as to determine whether the Warner Glasses fit.
