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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.
