What are “Polarized” Lenses?

Quality polarized lenses are designed to filter out harsh light and remove irritating glare from reflected surfaces such as water, snow, roads, buildings, cars and any reflective landscapes and objects. Good lens making with quality materials and processes, will result in polarized lenses providing a sharper, more vivid, and colorful view.  Your eyes will be more relaxed and comfortable with reduced squinting, facial and muscle strain. By comparison, non-polarized sunglass lenses are only tinted to block light, resulting in a more dull, muted view. They will not remove glare or the harsh irritating light that a good quality polarized sunglass lens filters. A great polarized lens will eliminate the discomfort of glare while providing sharper vision.

Why are Polarized Lenses Better?

While many sunglass non-polarized lenses and some value-priced polarized lenses block some or all harmful UV rays, not all sunglass lenses offer the protection you need, making your eyes and the surrounding skin more susceptible to burning, aging, cancer, and significant eye damage/disease.

We believe that eye health and sun protection is a very important factor to consider when choosing sunglass lenses. Every Tajima Direct polarized replacement lens and prescription lens will block out 100% of all harmful UV rays. This includes UVA rays that cause premature aging and UVB rays that cause burning. The Skin Cancer Foundation recommends quality lens technology for its ability to protect not only your eyes, but the surrounding skin as well. Think about those annoying crow’s feet and aging wrinkles caused by sun damage around your eyes – that could have been slowed or eliminated by wearing good, large wraparound sunglass lenses blocking UV rays like sunscreen protects your skin.

Are All Polarized Sunglass Lenses Created Equal?

Simply put, all polarized sunglass lenses are NOT created equal. There are wide disparities between polarized lens products that affect lens clarity, visual acuity, color, detail and depth perception. Not to mention durability, scratch resistance, weight and impact resistance. Lens materials are critical to understand. Just like a cut of beef, that are graded differently based on their quality, e.g., choice, prime, or kobe  – lens materials will also offer different levels of visual quality and performance. Marketing “noise” is just that. Buyer beware. The more educated you are, the better your purchase will be.

Most lens materials such as polycarbonate fit the “Choice” beef category. They’re inexpensive to make and mass-produced rendering only average quality. Nylon and CR-39 lens materials are also widely available commoditized lens materials. Each has their compromising downsides whether its weaker clarity, scratching easily or simply shattering. Glass lenses are optically good, but are heavy, can shatter, and have limited frame use-capability.

Only our patented Tajima Urethane™ lens offers an uncompromising accumulation of all the very best properties – visual clarity of glass, superior durability and scratch resistance, impact resistant and extremely light weight with zero distortion.
