How effective are polarized lenses?
Commercially available sunglasses with polarized lenses blocking 10 - 15% of incoming reflection, as well as specialized sunglasses aimed at athletes and professional drivers, are effective up to 99%.
A good quality pair of sunglasses with polarized lenses usually has the ability to block about 70% of the incoming reflection.
Many times, when choosing a pair of sunglasses, the question is "and what is the appropriate color of the lens?".
In some special cases, there are colors that will be preferred over others. But in general, the color of the lenses is a matter of personal preference and does not affect the effectiveness of lens protection at all. The cold gray is the one that least changes the colors of the environment.
The coffee gives a luminosity. Yellow increases the contrast of colors (night driving, hunting). In addition to the above, the lens material should also be taken into account. Children, as well as those who strain their glasses, will prefer organic lenses or polycarbonates, which are highly resistant to breakage.
Concluding, as for the sunglasses lenses, let us summarize that it must be 'UV400 protection'. Regardless of their color or material, they should be optically machined, that is, they should be uniform in texture, free of bubbles or foreign matter within the material mass.
In addition, optical treatment ensures the absence of deformation, which is responsible for intolerance and fatigue during the use of glasses.
