The index number on glasses, or lens index, is a measurement of how efficiently a lens material bends light, which determines the lens's thickness and weight. A higher index number means the lens is thinner and lighter, making it the best choice for stronger prescriptions, while a lower index is suitable for weaker prescriptions and is more affordable. The index typically ranges from a standard 1.50 for weaker prescriptions to high-index options like 1.74, which are the thinnest available.
