Feb 25, 2016 How Sunglass Readers and Polarized Sunglasses Help with Reading Outdoors Do My Sunglasses Need to be Polarized? Reading sunglasses are certainly a necessity on bright sunny days and colorful summer months. Whether you are headed to the beach, working in the garden, taking a brisk jog or simply strolling down a nice scenic path, grabbing a nice pair of sunglasses is second nature when the sun is shining. But what happens when your glasses aren’t working for you? Imagine you are going throughout your day and suddenly, a daunting glare overtakes your eyesight. Struggling to regain full sight, you are temporarily blinded. You might have even had this classic scenario: You are lying on a hammock or beach chair, trying to enjoy a good book as you enjoy the sunshine. But no matter which way you tilt your book or your head, you can’t quite seem to find the perfect spot that will avoid the glare. What does this mean? Even sunglasses can fall short from protecting your eyes if they are not polarized to fight unavoidable glare. In general, light shines and reflects in all directions. If you use a vertical light source like a lamp or the sun, you are better able to read. When light bounces off of water, sand or other reflective surfaces, it flashes straight at us and creates a strong, assaulting glare that causes eyestrain. To go even further, glare heightens the difference between light and shadow. While sunglass readers reduce light, enabling you to read outdoors, they do not eliminate the annoying glare that polarized sunglasses can. To eliminate glare, polarized sunglasses are covered with a unique film that blocks glare by filtering out horizontal light rays, while allowing vertical rays to enter. When you have polarized sunglasses, you are able to travel throughout the day without getting temporarily blinded. So how do you know whether or you not you have sunglasses that are polarized? The test is simple. Computer screens, like flat panel LCD models, emit light. If you have one, look straight into your screen wearing your sunglasses, and notice that the display appears normal. Now, tilt your head to the left or right and observe what happens. If the image got dim, then the image is polarized. If it didn’t dim when you tilted your head, then your pair isn’t polarized.
