WebJun 15, 2024 · The refractive index is a measure of the lens’s ability to bend light: The higher the refractive index, the more efficient the lens is at bending light and correcting vision. High-index lenses are therefore quite powerful. They can correct more severe vision problems while taking up the same or less space as other eyeglass lenses . WebIn simple terms, the higher the refractive index of a lens, the more it will allow thickness reduction when designing its surface geometry, according to the type of refractive error to be corrected and the power. High-index lenses are more complex than mid-index ones, and logically more expensive. shanks tenryuubito https://ca-connection.com
