UVProtect technology is built into all clear lenses by ZEISS. Why not add blue light protection if you're always on screens? Prescription sunnies or self-tinting lenses are also available in many great colours.

In addition to ZEISS UVProtect, all DuraVision coatings reduce UV reflections from the backs of your lenses. Supercharge your lenses with additional features of your choice.

The propagation of a Gaussian beam in a homogeneous, isotropic, local, linear, and nonmagnetic dielectric medium is studied using the angular spectrum representation for the electric field. The electric field associated with the Gaussian beam inside the dielectric medium consists of the paraxial result and higher-order non-Gaussian correction terms. It is shown that the second-order correction term satisfies an equation consistent with the recent work of Lax, Louisell, and McKnight. Numerical results showing the corrections to the paraxial approximation are presented.

A UV camera shows what that means: Clear lenses from ZEISS with UVProtect technology appear as dark as sunglasses because UV rays are completely blocked by the lens.

UV rays pose one of the biggest risks to long-term eye health. Because of their high energy, they can cause acute and chronic damage to the cellular tissues of the skin and eyes.

Not.so.fun fact: Many lenses that claim 100% UV protection only protect up to 380 nm meaning some harmful rays might still reach your eyes. Whether you’re looking for sunglasses or clear glasses with UV protection for everyday wear, be sure to check the fine print. Never settle for less than the ZEISS 400nm standard.

The material index impacts how thin and light your lenses are. Luckily all ZEISS lens indices come with UVProtect – because protection is as important as comfort.

Gaussian beam

Whether high, low or no prescription, everyone’s eyes need UV protection. That’s why we made it our standard. With ZEISS, you’re covered.

Many claim to have it – but it’s all about the nanometres. ZEISS clear organic lenses provide UV protection up to 400nm. That’s the same amount of protection provided by sunglasses and the standard recommended by the World Health Organisation.

Your optician may be able to help you figure this out. State-of-the-art tools like the ZEISS VISULENS® 550 effectively measure the levels of UV protection in your lenses.

You probably remember sunscreen and sunglasses on bright, hot days – maybe not when it's overcast? But UV rays are always there. With UV exposure up to 75% on cloudy days, your eyes still need protection.

Many clear lenses only marginally block UV – so some harmful rays might still reach your eyes. That’s because, once upon a time, it wasn't possible to produce clear glasses with UV protection up to 400nm without compromising the clarity and look of the lens too much. Driven by a passion for prevention and the preservation of healthy eyes, we decided to shake things up and challenge what once seemed impossible.

UV rays pose a major risk to long-term eye health. Its high energy can cause acute and chronic damage to the cellular tissues of the skin and eyes. Excessive UV exposure can cause your eyes to get sunburned – a condition called photokeratitis. It can also cause serious diseases like macular degeneration and cataracts – a frequent cause of blindness. Thankfully, ZEISS UVProtect in all ZEISS clear organic lenses provides sunglass-level UV protection for your eyes.

Study participants were asked to rate how important different aspects (“price”, “to see clearly across the entire lens”, “easy to adapt to”, “comfortable vision across the entire lens”, “aesthetics”, “available coatings”, “matches the frame”) are for them, when choosing new spectacle lenses.

While UV rays with shorter wavelengths may have higher energy levels, most of these rays are blocked by the ozone layer. Approximately 40% of solar UV irradiance that reaches the earth lies in the UVA range between 380 and 400 nm. To fully protect your eyes against the potentially harmful effects of UV, your lenses should therefore block rays up to 400nm.

UV protection is great for everyone – especially those who love the outdoors. Let’s help you find the right lens type that suits you best – for optics tailored to your lifestyle

Ultraviolet (UV) radiation lies between X-rays and visible light along the electromagnetic spectrum. It spans a range of wavelengths between 100 and 400 nanometers and is divided into three bands:

Your ZEISS lenses will have full UV protection – but there’s so much more to choose from. Let’s help you to find glasses that are perfect for you.

Young eyes have more transparent crystalline lenses, which let more UV rays through than adult eyes. Early sun damage can cause problems later in life. Standard also in our lenses for children, ZEISS UVProtect protects kids' eyes from the sun's harmful rays while they’re being active outdoors.

Lenses with UV protection up to 400nm – that’s the standard recommended by the World Health Organisation. That’s sunglass-level protection. That’s what you’ll get in your clear ZEISS lenses – thanks to our scientists challenging what once seemed impossible.
