Index is a dependable full-frame reading glass built for everyday use. The strong, stable frame holds optical-grade lenses that provide clear near-vision whether you’re reading books, checking screens, or tackling daily tasks. Spring hinges add controlled flexibility for repeated on–off wear, and the balanced proportions suit a wide range of average face sizes. Available in multiple strengths, Index delivers straightforward comfort and reliable visual support without fuss.

This style is available with two optical-grade lens options, depending on configuration:

PMMA Acrylic Lenses

CR-39 Optical Lenses
