Semi-Rimless Frame: 1.6 Index
Eye see trouble - act fast!
If vision's at stake, don't hesitate.

1.6 index lenses are often used in semi-rimless frames for several key reasons:
- Thinness: 1.6 index lenses are thinner than standard lenses. This is especially important
for semi-rimless frames, which expose the edges of the lenses. Thinner lenses provide
a more aesthetically pleasing look, reducing the noticeable edge thickness. - Lightweight: These lenses are also lighter in weight compared to lower index lenses.
Since semi-rimless frames have less structure to support the lenses, lighter lenses
help maintain comfort and ensure the frames stay securely in place without putting
extra pressure on the nose or ears. - Strength and Durability: 1.6 index lenses are made from high-quality materials that offer better resistance to scratches and impacts. Semi-rimless frames rely on the strength of the lenses to maintain their shape and support,
so using more durable lenses helps in preserving the integrity of the eyewear. - Edge Thickness: Since 1.6 index lenses are thinner, the edges are less prominent.
Thicker lens edges in lower index lenses can be more prone to chipping, especially
in semi-rimless frames where the lens edges are exposed.
