Such lenses are called “high index” and stronger corrections are more attractive because they are slimmer. High index plastic uses less material so they are often lighter in weight. High index lenses are thinner because they’re designed to bend light better. Well, the difference between those is called their refractive index, it has to do with how quickly light passes through the lens material.

The more that light must refract, the slower the speed of light is certainly going through the material. Which means that the better the lens is for refracting the light, the bigger the index of refraction is for the lens.
