According to experts, rising temperatures, stronger sunlight and higher UV radiation are side effects of climate change. In addition, the warmer weather means that we spend more time outdoors. Optimal eye protection is therefore becoming increasingly important.

Help, it's dazzling! If you want to buy sunglasses, you have a wide choice. But what criteria are crucial to ensure both good vision and the best possible eye protection? A professional gives tips.

Look for the CE mark
When buying sunglasses, it is essential to look for the CE marking, which offers 100% UV protection. An underestimated risk is the so-called scattered radiation, which can account for up to 40 percent of UV exposure. Be careful, this also occurs in the shade and can damage the eyes. The Federal Guild Master of Opticians and Contact Lens Opticians, Markus Gschweidl, therefore recommends wearing sunglasses even when it is cloudy.

Don't let yourself be dazzled
Arm yourself against glare too! "High light intensity overstrains the eye and impairs vision. This can be particularly dangerous when driving," warns Markus Gschweidl. Sunglasses that are always available in the car are a good idea.

Different tint categories of sunglasses are easier on the eyes. For summer vacations in sunny regions, category 3 with 82 to 92 percent light absorption is recommended, while category 4 with 92 to 97 percent makes sense in high mountains or on glaciers.

Self-tinting glasses
Photochromic sunglasses that adapt to changing light conditions are also a good choice. The expert advises self-tinting sunglasses with a spectrum between 40 and 80 percent light absorption. A polarizing filter can also reduce reflections and is particularly suitable for water sports or general light sensitivity. Seek advice!

Caution with children!
Children's eyes are more sensitive than those of adults. As the little ones have larger pupils and clearer lenses, more UV radiation penetrates into the eye. They should therefore wear well-fitting, covering sunglasses from an early age. A visor cap or a wide-brimmed sun hat offer additional protection.
