Thats not true, I have glass aspherical lens.
- glitchc 4y agoThat you wear for prescription glasses? Unlikely. Glass cannot be shaped into aspheres without very expensive grinding and polishing techniques. Multiple glass shapes are typically molded together to make an aspheric lens. The challenge is that molding the lens this way decreases the Abbe number significantly, which is why it’s not used for prescription eye glasses. If you have astigmatism, your lenses are most likely a polymer of some sort. Check with your optometrist.
- not_the_fda 4y agoI know exactly what I have. You can even get glass progressive lenses which are very aspherical. https://lensfactory.com/collections/progressive/products/progressive-premium-thin-glass-lenses-1-60 https://lensfactory.com/collections/progressive/products/pro...
