Rx-Safety offers several different lens materials for prescription glasses. If you are interested in high index plastic, the material that we recommend most is Thindex 1.70 due to its optical clarity, light weight, and thinness.
Thindex 1.70 is a Vision Ease brand lens and can be purchased in clear or with a tint, and it is not available as a lined bifocal. Thindex is most commonly ordered in our flat, fashion-style frames, but it is also available in single vision in a wraparound frame.
If you have a strong prescription, however, and are looking for the thinnest, lightest lens possible, then Thindex 1.70 is for you. We recommend that if you order any high index lens on our site, you also order anti-reflective coating since high index generally causes more glare than other lens materials.
If you have any questions about Thindex or any of our other lens options, please don’t hesitate to give us a call. One of our staff members will be happy to help you pick your perfect pair of prescription glasses.
