With so many types of lenses available in the online market today, it becomes confusing to find the right ones. But, the most popular and essential ones are polarized lenses. These are specially coated lenses featuring a chemical film that reduces the glare caused when sunlight is reflected off from horizontal surfaces. This glare can be disturbing to the eyes and obstructs your vision. This is why it is recommended to wear polarized lenses that will neutralize the glare, enabling you to see clearly.
Polarization: How It Works
Whether it is summer or winter season, sunrays are always surrounding you when in outside environment. When these rays hit a flat surface, a reflected light gets back to your eyes, causing glare that not only distorts your view but also reduces your depth perception, leaving you blind for a few seconds.
Now you must be thinking of how polarized lenses actually contribute to this. So, here is how they work. Unlike regular sunglasses that only reduce the glare reflecting in your eyes, polarized sunglasses absorb horizontal light waves with the help of that special chemical coating. This enables you to see flawlessly without any discomfort.
Choose a high quality pair of sunglasses having polarized lenses and it will benefit you in so many ways:
