Product Overview
Description
Selecting the right lens refractive index is essential for achieving optimal vision correction and comfort. The refractive index determines how efficiently a lens bends light, affecting its thickness and weight. For low prescriptions (SPH ±2.00 or less), a 1.50 standard index is cost-effective and suitable for everyday use. A 1.56-1.60 mid-index lens is ideal for moderate prescriptions (SPH ±4.00 to ±6.00), offering a balance between thinness and durability. High-index lenses, such as 1.67 and 1.74,are recommended for high and very high prescriptions (SPH ±6.00 and above), providing ultra-thin and lightweight options that enhance comfort and aesthetics, especially for rimless or lightweight frames.
