The refractive index of lenses of the same material with the same prescription will determine the thickness, aesthetics and price of the lenses. The higher the refractive index, the lighter, thinner, more beautiful and more expensive the lens will be.
The thicker the lens, the smaller the refractive index of the lens, the higher its Abbe number will be, the higher the Abbe number, the better the imaging effect will be. If you just pursue high refractive index lenses, the lenses will become thinner, but the Abbe number will also be reduced. As the saying goes, you can't have your cake and eat it too, refractive index and Abbe number have always been in love with each other on the lens.
