What Makes You See Rainbows Through Polarized Lenses And Why?
Are you a polarized glass user? Have you ever seen rainbows through your glasses? Perhaps you see a tiny black spot through your car's window. This effect is not possible with traditional lenses. However, your mind isn't playing tricks on you. You are actually seeing rainbows, and there's lots of science behind it.
What are POLARIZED LENSES?
Before we discuss why rainbows might appear when you look through polarized lens, let's first explain what polarized lens are. Different wavelengths of light have different wavelengths. Some are horizontal, others vertical. Polarized lenses work in the same way as blinds. They block horizontal light and contain chemicals. They are placed vertically to block oncoming light. Polarized sunglasses will block out most of the harsh sunlight, so you might notice things appearing darker. However, they will also appear crisper and more clear.
WHY DO I SEE A RAINBOW THOUGH MY POLARIZED LASES?
WHY DO I SOMETIMES FEEL DARK STRIPES IN MY WINDSHIELD
Tempering is a process that glass undergoes to prevent it from shattering in an impact. This can result in dark stripes appearing on your windshield. The tempering process involves rapidly heating and cooling the glass, creating polarized areas known as "stressed Birefringence". Combining the polarized filter on your lenses with the polarization spots in glass creates "dark stripes". This effect can be easily ignored but many people keep an extra pair of nonpolarized glasses or lenses on hand to avoid getting the "dark stripes" effect while driving.
