Sunglasses aren’t just a summer staple. In fact, optometrists recommend wearing sunglasses year-round for optimal eye health. Tom Cruise and Audrey Hepburn were on to something. Not all lenses are created equal, however. Polarized lenses offer a host of advantages that should be considered when purchasing eyewear.

When sunlight is reflected off of water, snow, windshields, passing cars, and other bright surfaces, it causes visual noise or that pesky glare. Light travels in all directions and standard sunglasses filter light equally, yet polarized lenses filter the light selectively and absorb light waves from various angles, while also protecting against harmful UV rays.

The reflections from horizontal surfaces are blocked by the lens molecules and light enters the eye vertically. You only see the real image because the interfering glare is diminished. For example, you’re enjoying a sunny afternoon on a fishing excursion. When you look down at the water, you see the sky, trees, and other surroundings reflected off of the surface, making it extremely difficult to actually see into the water. If you’re wearing polarized lenses, these reflections are blocked. Instead of staring at your own face mirrored in the water, you can view what’s under the water.

The sun light reflected by any surface, for example, while driving, walking on the beach, or skiing on the mountains, is polarized light.

Polarized lenses block the blinding glare that bounces off horizontal surfaces, for reduced eye strain and great comfort.


  • .75 mm Polarized Lenses
    Made from extremely thin film, .75 mm lenses are perfect for the casual wearer, as they’re not as resistant to breakage.
  • 1.1 mm Polarized Lenses
    These lenses are made with thicker sheets of film. While they have the same properties as their thinner counterparts and aren’t any stronger when it comes to nixing glare, they have more resistance to impact. If you’ll be wearing your shades while playing sports or just have a propensity for dropping things, these are a better bet.
  • Glass
    Polarized glass lenses offer the highest standard of polarization, photochromic qualities, and scratch resistance. The price tends to be a little higher for glass lenses as opposed to plastic.
  • Polycarbonate (plastic)
    Though plastic lenses may scratch more easily and might not have the same optical quality as glass lenses, they are lighter and can be more comfortable. They’re also extremely durable and less prone to breakage. They typically cost less than glass lenses.

  • Safety

    Polarized lenses reduce glare so you don’t have to worry about being blinded on the road when that silver sports car goes zipping by. You will be able to see clearer images while reducing eye strain and fatigue. This makes activities, such as driving, much safer. Glare can be extremely uncomfortable for those who already have vision problems or are prone to migraines. Polarized lenses eliminate this issue. No more squinting! Polarized lenses with full UV ray protection, keep your eyes safe from the damaging effects of the sun’s ultraviolet light. UV rays can harm the eyes’ lenses and corneas, boost the odds of suffering from cataracts down the road, can cause photokeratitis, a corneal sunburn often referred to as snow blindness, and ravage the thin, fragile skin of the eye area. Polarized lenses preserve the health of your eyes.

  • Improved Vision
    With the glare filtered out, you see whatever is actually there and aren’t distracted by reflections. Polarized lenses are like the superheroes of sunglasses. Colors are purer, details are precise, contrast is sharper, and your surroundings are crisper and clearer when wearing polarized sunglasses, hence the enduring popularity of Ray Ban shades.
  • Comfort
    Anyone who’s squinted their way through a drive trying to make out objects that were distorted by a glare knows that the eyes get tired, irritated, red, and strained. Plus, this can lead to a headache. Polarized lenses make it possible to frolic in the sun and around any surface without having to compromise your visual comfort.


Those who engage in outdoor sports drive frequently, or just want to reduce glare, will find polarized lenses better suited to their sun protection needs. There are a few cases when you should not wear polarized lenses. Polarized sunglasses make it difficult to see images on an LCD screen so those who rely on an LCD screen, such as operators of certain heavy equipment and pilots, shouldn’t wear them in these instances. In addition, polarized sunglasses are not recommended for night driving or for downhill skiing if you have difficulty distinguishing between regular snow and icy patches when reflections are absorbed. Polarized lenses come in prescription and non-prescription form. Even if you wear bifocals, you will be able to take advantage of these lenses. Your eyewear professional can point you in the right direction.
