Lens Index Guide

Lenses come in different indexes, which determine their thickness, weight, and visual clarity. Higher-index lenses are thinner and lighter, ideal for stronger prescriptions, while lower-index lenses are more affordable and standard for mild prescriptions. Choosing the right lens index ensures comfort, style, and optimal vision, tailored to your prescription and lifestyle.
