At VS Eyewear, we offer custom high index glass lenses in a variety of prescription designs, including single vision, bifocal, and progressive lenses, helping you achieve a slimmer profile, improved comfort, and crisp, distortion-free vision in your favorite frames.

More Information

ORDER NEW HIGH INDEX GLASS LENSES AND SEND US YOUR FRAME â€“ Premium quality lenses for any brand of frames you may have. No hassle process and quick turn-around time. Getting high-quality High Index Glass lenses for your glasses are easy to get at VS Eyewear. Most online optical stores will try to sell you new frames even though all you need are replacement lenses. If you have a set of frames with prescription lens replacements then you’re in the right place.

High Index Glass Facts - Eye prescriptions below +/-4.00 can benefit from our standard 1.53 or 1.60 lenses. We recommend 1.70 or 1.80 high-index lenses for people with prescriptions between +/-4.00 and +/-8.00, and 1.80 & 1.90 high-index lenses for people with prescriptions +/-8.00 and higher. We highly recommend purchasing an Anti Reflective coating with the high index lenses since they reflect a considerably higher percentage of light than standard lenses.

The positive qualities of high index lenses apply to a large group of corrective eye-wear consumers but not to all. If your prescription is a relatively weak one, the weight and thickness variations between standard lenses and high index lenses would not vary all that much. If high index lenses cannot offer you a noticeable reduction in thickness or increase in appearance, they may not be worth the higher cost to you. The standard lenses offer offer a much higher Abbe value, so the lenses will be superior in vision quality than the high index lenses. The high index lenses are very dense, so they will have added weight.

High Index Glass Lenses are typically heavier than polycarbonate or plastic lens material in general. So, when choosing a pair of glasses, you should select a frame that offers a smaller eye size or provides an adjustable nose pads so you will not feel any additional weight. This should significantly reduce any weight differences you might notice while wearing glass lenses.  Normally smaller round and oval frame shapes work best for appearance with the highest prescriptions.

Frequently Asked Questions

High index glass replacement lenses are ultra-thin, high-density optical lenses designed for strong prescription vision correction. Unlike standard plastic or standard glass lenses, high index glass bends light more efficiently, allowing high-power prescriptions (such as high myopia or hyperopia) to be crafted with significantly thinner edge profiles and superior visual clarity.

VS Eyewear offers high index glass replacement optics in 1.70, 1.80, and 1.90 refraction indices. The higher the index number, the thinner the lens profile will be for strong prescriptions. For example, 1.90 index glass is among the thinnest optical lens materials available anywhere in the world.

Yes. With our lens replacement (re-lensing) service, you can send your existing frame—whether it is a classic metal, acetate, or vintage frame—to the VS Eyewear optical laboratory. Our technicians will custom-cut and precision-mount new high index glass lenses directly into your frame.

High index glass offers three distinct optical advantages: unmatched scratch resistance, exceptional chemical durability, and superior Abbe values. Glass lenses deliver far crispener visual fidelity with drastically reduced peripheral chromatic aberration (color fringing) compared to high index plastic or polycarbonate options.

Because optical glass is naturally denser than synthetic polymers, high index glass lenses carry more weight than plastic. However, because high index glass is so efficient at bending light, the lenses can be ground much thinner, which significantly offsets the added weight—especially when paired with small-to-medium-sized metal or acetate frames.

Yes, and an Anti-Reflective (AR) coating is highly recommended. Higher index optical glass naturally reflects more surface light than standard lenses. Applying a premium AR coating eliminates harsh glare, reduces internal reflections, improves night driving vision, and enhances the aesthetic appearance of your glasses.

High index glass lenses are best suited for full-rim metal or acetate frames. Because high index glass can be brittle along ultra-thin edges, rimless (drill-mount) or semi-rimless (grooved wire) frames carry a higher risk of edge chipping. Full-rim frames provide essential perimeter protection to keep your glass lenses safe.

Our domestic custom optical laboratory can craft high index glass lenses across a full range of vision corrections, including Single Vision (distance or reading), Lined Bifocals (FT-28), and Progressive (No-Line) multifocal designs tailored precisely to your prescription parameters.

Clean your high index glass lenses using a mild lens spray and a soft microfiber cloth. Because real glass features a hardened surface, it resists daily wiping friction and chemical exposure far better than plastic. However, always rinse off loose grit or dirt with water before wiping to protect any applied Anti-Reflective coatings.

The process is quick and simple: select your high index glass options (index, vision type, and coatings) on our site, enter your prescription details, and submit your order. Print your prepaid shipping confirmation, send your frame to our custom optical lab, and our certified opticians will cut, edge, polish, and mount your new high index glass lenses before shipping them back to you.
