Polarized lenses: what are they?
For people who practice sports, professionals or simply enthusiasts, it is important not to underestimate the choice of glasses that guarantee optimal and comfortable vision. Polarized lenses are definitely the best because of their ability to eliminate glare. This particular technology can be applied to any type of lens, single vision or progressive, guaranteeing more than satisfactory results.
WHAT IS MEANT BY POLARIZED LENSES?
To answer the question, it is necessary to explain how the polarizing principle operates. When a ray of sunlight encounters a reflective surface, such as asphalt or sea water, the light undergoes a process called polarization and begins to move vertically and horizontally. While vertical light provides the human eye with all the useful information about colors and contrasts, horizontal light creates that glare effect that disturbs our vision.
This is where the polarized lens comes into play, a real barrier that protects the eyes from horizontal radiation, allowing only rays from direct light sources to pass through, in order to eliminate annoying reflections.
THE ADVANTAGES OF POLARIZED LENSES
The use of polarized lenses is suitable for anyone who does not suffer from particular visual defects. Thanks to their conformation, in fact, polarized lenses significantly reduce the reflected light energy allowing: better vision and therefore a perception of contrasts and depth; a clear view of the images even in the distance; a natural vision of colors; less eye fatigue caused by glare and glare of light, maximum protection of the eyes from UV rays as well as maximum comfort.
Unlike polarized glasses, classic sunglasses can only attenuate this reflective effect, but the feeling of blindness and glare remains.
POLARIZED LENSES: IDEAL VISION FOR ALL TYPES OF SPORTS
Lenses equipped with these special filters are particularly useful while driving and in all activities that have to do with reflective surfaces such as water, snow, ice, etc. Polarized sunglasses can therefore be used outdoors and during all those sports where vision is disturbed by the presence of reflected light, such as: fishing, skiing, cycling and water sports.
For those who love the sea or are looking for glasses to go fishing or boating, polarized lenses are the best choice: they eliminate the reflection from any flat, regular or shiny surface, promote clearer and sharper vision and allow you to see below the surface of the water.
The same goes for those who practice road or dirt sports and are looking for glasses for running, cycling or mountain biking, with this type of lens it is possible to eliminate the glare of the road surface, relax the visual system and not suffer from sudden changes in light conditions.
POLARIZED LENSES IN THE NAME OF COLOR
Like all sun lenses, they are available in different colors:
– Brown polarized lenses are the most versatile, as they maintain clear and bright vision from morning until sunset.
– Pink lenses, similar to brown in features, add a pinkish tint.
– Green lenses are best when you are in varying lighting conditions, such as when switching from strong to softer light.
– Gray lenses are ideal in situations of direct and intense light, because they allow you to view colors and contrast at maximum clarity.
Therefore, for glare-free vision, experts recommend the integration of these polarized filters and a suitable lens treatment that protects them and makes them as resistant to breakage as possible. The frame is also fundamental, which must be durable and preferably made of robust, light and unbreakable material.
Considering the protection and comfort that polarized glasses can provide to our eyes, we believe that we should all have at least one pair. The first rule is to rely on the advice of an expert, who will be able to suggest the lenses that best suit our needs. The specialist will also be able to assess the presence of specific contraindications that may interfere with the correct use of these polarized lenses.
