In recent years, many of the sunglass brands have added polarized glasses in their product catalogs and fashion lines.
Polarized sunglasses are a technical advancement that has made it possible to reduce the amount of light that reaches the eyes, reducing eye fatigue.
How do they work?
The light our eyes receive comes in three forms: horizontal, vertical and circular. Polarized eyewear has a filter that blocks the sunlight that reaches us horizontally and allows the passage to the vertical light, with which we can clearly see.
What are the advantages of polarized glasses?
- Annoying reflections
- Fatigue of the eyes
Places where glare is common: snow, sea, roads where the sun reflects on surfaces; like windows or glasses, etc.
Glasses with polarized lenses increase the driver’s safety and avoid reflections that prevent poor vision while driving. The following video explains the characteristics of the polarized glasses Xperio of Essilor.
How can you tell if the glasses are polarized?
Usually written on the eyeglass frame or on the lens itself, a “P” or simply “Polarized”. However, if we have doubts, a quick test can be done at home that looks like this: If you have acquired polarized glasses, put on your glasses and look at a computer monitor. Turn your head from side to side and you will notice that the image of the monitor is erased or darkened depending on the angle you are looking at. This is proof that it is polarized glasses.
Sunglasshutusa and her HD Polarized Eyewear
Unlike other manufacturers who use filters on their lenses over multiple layers, Sunglasshutusa uses only a thin and powerful layer. This allows for better visibility, without distortions on the lens, as other brands can cause.
One of the most interesting aspects of this brand is its way of manufacturing. Both Sunglasshutusa lenses are made at the same time to ensure that the shaft is the same at all times. In this way, the curvature of the light is avoided by possible inconsistencies of the lenses.
