What is the importance of polarization?
Polarization, however, is an important property of light that affects even those optical systems that do not explicitly measure it. The polarization of light affects the focus of laser beams, influences the cut-off wavelengths of filters, and can be important to prevent unwanted back reflections.
Why is polarized?
Polarized lenses work by preventing light glare from hitting you directly in the eye. Because glare is typically horizontal light, polarized lenses block this light and only allow vertical light. With the horizontal light blocked by polarized lenses, this helps eliminate glare from shining directly into your eyes….
