How to connect the marines with glasses
Polarizing glasses are not only a sensible investment for athletes and drivers, they can also prove to be very useful in everyday life.
Polarizing glasses - what exactly are polarizing glasses?
The eyes are always exposed to light, especially outdoors. For example, in sports on the water or winter sports such as skiing. Reflections on the water or snow blind the eyes and quickly lead to symptoms of fatigue, because the retina always tries to optimally adapt to the constantly changing light conditions.
Polarizing glasses are the solution here, because they are able to intercept the corresponding light reflections from the field of view and ensure a clear view. The light only reaches the eye in a subdued form and is no longer dazzling. You see much clearer and sharper. The perception of the colors also improves.
The advantages of polarizing glasses are particularly evident when doing sports or driving a car. Normal sunglasses are usually not enough to keep reflections and glare away. When driving a car with polarized glasses, the integrated polarization filter allows oncoming vehicles to be recognized much faster on wet roads. In the sports sector, anglers in particular like to use polarizing glasses in order to be able to better see the fish under the water surface.
How do polarizing glasses work?
Light usually shines in all directions - it's unpolarized. If polarized light hits a flat surface, this reflects the light horizontally and vertically. The light is then called polarized. The vertical rays in particular cause the undesirable glare in the eyes. If you wear glasses with polarizing glass, the glass has a special plastic coating on which tiny crystals are arranged in horizontal rows. These absorb the vertical radiation and only let the horizontal radiation through to the retina.
What are the pros and cons of polarizing lenses?
Basically, of course: Where there are advantages, there are also disadvantages - this is no different with polarized lenses. In addition to the reflections from the road, the polarization filter also filters out the light from illuminated dashboards in the car or the light from GPS displays. They can then only be recognized as weakly glowing points. Another disadvantage is the price. Polarizing lenses cost significantly more than normal lenses for sunglasses. Due to the special plastic coating, they have to be made with a significantly higher amount of work. However, the advantages of polarizing glasses clearly outweigh them. Disturbing light reflections are faded out, the contrasts when seeing are increased and colors are perceived more intensely. Therefore, the eyes tire more slowly overall. This is particularly beneficial for drivers, athletes and people who are often outdoors.
