The light’s wavelengths make the difference here – the shorter the wavelength, the higher the energy and also the riskier the radiation. Every area of the spectrum of radiation has a different impact. Dangerous and unpleasant: the sunlight’s reflections on smooth surfaces.

The visible light represents a partial risk to the human eye. Especially in the region between 380 and 500 nanometres (nm), the visible blue light can cause damage to the eye. Irreversible photochemical reactions in the eye – such as macula degeneration, for example – can be a result of blue light.
For some time, there has been the possibility for the eyes to be protected from the hitherto underestimated blue light by means of sunglasses with special blue light filters.

Sunlight, which breaks on smooth surfaces, such as water or asphalt, generates an unpleasant glare. The reflected light is many times more intense than non-reflected light, and makes the eyes tire more quickly.
The future of sunglasses therefore lies with pol technology, through which reflections are eliminated, contrasts strengthened and colours perceived without distortion.
