Glass Lenses for Progressive Lens Wearers: Lenses for Fans

Further development of the ZEISS progressive glass lens portfolio – why it is a must-have.

Thanks to properties such as low weight and high shatter resistance, plastic lenses have gradually overtaken glass lenses – at least if sales figures are anything to go by. However, at ZEISS, we attach just as much importance to the further development of our portfolio of glass lenses. After all, lenses made with this material come with their own special benefits. The ZEISS progressive portfolio is in focus here. The first eyeglass lens in the world is known to have been made of glass. Developed by Assyrian artisans in the eighth century BC, glass lenses were just as perfect for eyeglass wearers then as they are today due to their excellent optical properties.

Are you particularly exposed to dust or dirt at work or when pursuing your hobby? Are you a big fan of the purity and optical performance of glass lenses? Or do you attach a great deal of importance to the durability of your lenses? If so, ZEISS glass lenses may be the solution for you.

Plastic lenses are obviously the first choice for sports glasses or children's glasses, as they are lighter and more shatter-resistant. But it is no coincidence that precision optics, such as camera, microscope and telescope lenses, and the touchscreens on modern smartphones are made of glass. This material provides a highly durable, smooth and scratch-proof surface, helping to prevent fine scratches developing on the lens in dusty surroundings.

What is more, high refractive indices allow thinner lenses to be produced, making you look more attractive and your eyes more natural - even with higher prescriptions.

The major benefits of glass lenses at a glance:

  • Excellent optical performance
  • Greater surface hardness
  • High scratch resistance
  • Outstanding durability

Unfortunately, many eyeglass lens manufacturers are no longer investing in the development of their glass lens portfolios. However, fans of glass lenses need not worry, because they can now benefit from ZEISS's optimized portfolio of progressive glass lenses. Zeiss progressive lenses can be customized like a tailor-made suit thanks to freeform technology and are now available in any possible combination with regard to eyeglass frames, lenses and prescriptions. Furthermore, ZEISS progressive glass lenses can now also be customized for the intermediate and near vision ranges. To give you brilliant vision particularly at night, dawn and dusk, your ZEISS eye care professional can also customize glass lenses for you using i.Scription® optimization.

The secret of glass lenses lies in the strong material cross-linkage and the molecules' dense 3D structure. This guarantees a long performance life because the hard, smooth surface prevents fine scratches from developing in the first place.
