UV radiation – A real danger to the eyes!
UV rays can cause not only short-term discomfort – such as glare, inflammation or other eye problems – but also long-term, irreversible damage. These include juvenile cataracts or macular degeneration. Because these rays are completely invisible and cannot be felt, they are even more dangerous. This is why 100% UV protection is essential all year round.
In some circumstances, UV rays can be even more dangerous:
Harmful effects of UV radiation
It is important to be aware that almost half of all blindness in the world is caused by the onset of cataracts. In many cases, the harmful effects of prolonged exposure to UV radiation, which clearly increases the risk of developing eye damage, may also be responsible. Just as we protect our skin with different sun creams, it is equally important to protect our eyes from the sun’s rays. While some eye damage is reversible, some of it is unfortunately permanent and can lead to complete loss of vision. As mentioned above, UV radiation has been linked to the development of cataracts, but it can also be responsible for the development of ciliary epithelium, certain retinal lesions and even malignant tumours.
Prescription sunglasses lens colors
For dioptric sunglasses, the choice of lens colour is just as important as perfect dioptre and 100% UV filtering. There’s also a wide range to choose from, so you’re sure to find the right pair for you – depending on the conditions you’ll be using them in. In addition to the common sunglass colours such as brown, greenish-grey or grey, there are many other colours to choose from. Now let’s take a look at some of them and see which ones are the best choice for you!
The pale yellow or orange colours have an excellent contrast enhancing effect, making them ideal for driving, sporting, hunting or shooting. Pale blue, for example, can enhance contrast on large concrete surfaces or tarmac by making the scene stand out against a grey background. Brown, on the other hand, pushes the colours of the scene towards the greenish tones, giving a more pleasant, natural visual experience and making the environment appear more welcoming. Whichever colour you choose, it’s available in both single and multifocal lenses!
Selective light absorption for better contrast
The main cause of stray light is blue light, which can impair and disturb our vision. This is where ZEISS Skylet® colours can be of great help to our eyes. Thanks to their improved absorption properties, contrast perception and colour vision can be significantly improved. They help us to see more calmly and clearly, even in extreme lighting conditions.
Can I request a dioptric sunglass lens for my favourite frame or my existing sunglasses?
YES, we have an extremely wide range of frames, with most of the world’s brands available in stock or to order. In addition, with the help of a specialist, we can also replace lenses in existing sunglasses!

Prescription sports glasses lenses
These lenses are perfect for use in specially curved frames, sunglass frames or curved fashion eyewear. They are available in colourless, light-darkened, polarised and coloured versions. The single-focus PhotoFusion (darkened) and polarised versions are 100% UV-filtered, but the colourless version can also be ordered with a 100% UV-filtering layer! Base curvature : 7.00
As with all ZEISS lenses, the sports lenses are available in a premium Individual version, where the lens is fully customised for maximum visual experience.
Dioptric sunglasses - polarised lenses
A common disturbing phenomenon, for example when driving a car or on a waterfront, is the reflection of light from horizontal surfaces as a strong glare. This can be almost blinding. Polarised lenses reduce this phenomenon to such an extent that you can see without squinting, so you can see more comfortably in extra bright conditions, with 100% UV filtering. Wearing them during the day is recommended for extreme sports, driving, water sports and winter sports.
ZEISS AdaptiveSun polarized tints
The secret of sunglasses lenses with polarized filters:
When light reflects off a flat surface, such as when sunlight reflects off a wet road surface, the water will reflect some of the light. This can cause glare, which can be reduced by using sunglass lenses with polarised filters. These simply filter out the horizontally oscillating light elements – the reflected light is horizontally polarised, which is filtered by the vertical micro-mesh structure of the polarised lens – so that vision is calmer and safer.
Smart sunglass lenses that adapt to changing light conditions
ZEISS AdaptiveSun dioptric sunglass lenses change their darkness depending on the level of UV radiation, while providing continuous UV and glare protection.
There is a reason why we find it difficult to see clearly and sharply in changing lighting conditions. Even when wearing sunglasses with UV protection – which reduce glare and provide more comfortable imaging – we may have difficulty seeing in constantly changing light conditions. Lenses may be too dark in a shady place, but they can also be too bright when we are in bright sunshine. We tend to take off our sunglasses, leaving our eyes unprotected.
What does the ZEISS AdaptiveSun lens do?
Fast
For greater comfort, these lenses adapt quickly to changing light conditions, darkening in 18-35 seconds.
Dark and darker
ZEISS AdaptiveSun lenses darken intensely in sunlight for an optimal viewing experience. The default light filtering is 60%, but when activated the light filtering can be up to 97%.
Colour consistency, glare protection
The colour tone of ZEISS AdaptiveSun lenses remains unchanged while the lens darkens. The sunglass lenses are also available with a polarised filter to protect against extreme and glare light.
