POLARISING
LENSES

Polarisation: Avoid annoying reflections

The road is wet and the sun comes out – we have all been there. Especially when driving a car, annoying reflections can impair vision significantly. Polarising lenses almost completely eliminate reflections from wet roads, water, windscreens, snow and ice. Normally sunlight scatters in all directions – if the light waves hit water, wet roads or snow, for example, the light is reflected by these surfaces and focused in one direction. This causes an unpleasant glare effect and reduces contrast sensitivity. Polarising lenses prevent this glare effect and ensure that the reflected light waves cannot reach the eyes. As a result, the polarising lenses also provide greater contrast sensitivity and improved colour perception. Polarising lenses can be extremely useful for athletes, drivers and pilots, in particular, to reduce the risk of accidents – due to the glare effect of a wet road, for example.

The Eagle Eyes Added value

In addition to blue light, the Protect Eagle Eyes material also filters out the light spectrum between 580 and 590nm. This results in a massive increase in contrast even in poor visibility and especially at night. The combination of UV420 and yellow light filter makes the Protect Eagle Eyes material the ideal companion in front of a PC or at the wheel – this lens material offers 24-hour protection without changing glasses. You will learn to love Protect Eagle Eyes lenses, especially when driving at night. Glare disappears, distances are easier to gauge and objects can be detected much earlier.

See the benefits for yourself

See the benefits for yourself The slightly bluish lenses (approx. 10% tint) are ideal for day and night. They support everyday activities by improving our ability to recognise differences in light and colour. This results in clearer vision and greater colour contrast. And all this can be achieved in the material without additional coating.

Reduction of the light spectrum

The light spectrum is reduced completely up to 410nm and by 86% between 410-420nm. An additional reduction of the light spectrum at 585nm enables glare-free and high-contrast vision.

INFRARED PROTECTION IN OTHER SECTORS

In dermatology, in particular, research has already progressed and there are relevant studies on the harmfulness of infrared radiation that have already been incorporated into the development of new sun protection creams. The opinion held by manufacturers of these sun protection products is “without infrared protection you are only half protected from solar radiation”, because infrared rays represent more than 40% of the sunlight spectrum.

DEVELOPMENT OF SUN PROTECTION PRODUCTS

After initial suspicions in the middle of the 19th century that UV light could be harmful, Crookes sun protection lenses that guarantee 100% UV light protection appeared in 1913. In 1908 the Swiss ophthalmologist Alfred Vogt was able to prove it. In 1926 he published his summarized findings that ultraviolet light has a damaging effect on the eye. Incidentally, it should be mentioned that he already pointed out that infrared radiation should also have a similarly damaging effect. In 1930, the first series of sunglasses were produced in which the issue of glare protection still played a major role. In addition to the fashionable aspect of sunglasses, protection standards have been developed, such as the EN1836 standard, which speaks of complete UV protection as soon as there is an absorption of 95% in the range up to 380nm. The more popular standard and, above all, known to every end user, is now the UV400 seal, which intervenes in the visible light and also blocks harmful high-frequency blue light. We ask ourselves: what happened to infrared protection?
