“We must look at the lens through we see the world, as well as the world we see, and that the lens itself shapes how we interpret the world.”― Stephen R. Covey,
Sunglasses come in all shapes and sizes. There’s aviators, wayfarers, submariners, cat eye, and many more. But no matter what your style may be, your lenses are what ultimately make the sunglasses. According to Mike Dahlroth from Randolph, a cheap pair of lenses can be damaging to your eyes, will scratch easily, and offers subpar visual clarity. A high-quality pair of lenses will block out 100% of UV rays, offer lasting durability, and provide perfect optical clarity. Our premium designer lenses are the perfect shades for the best results.
At IVI Vision our sunglasses are fitted with premium quality sun lenses from Carl Zeiss Vision. Zeiss is a top of the line, innovative company that has fostered the technical application of lenses from sunglasses to satellite optics. For 100 years, the ZEISS name has been synonymous with better vision. ZEISS optics were instrumental in the discovery of Pluto and were there when a man took his first steps on the moon. They have helped Nobel Prize-winning scientists and Oscar-winning directors create their work. Building on the company’s earlier optical expertise, ZEISS turned its sights to vision care and, by 1912, produced its first precision eyeglass lenses.
At ZEISS, they have put over a century’s worth of visual experience and innovation into everything they create and take pride in staying on the leading edge of optical technologies. Before the lenses even touch IVI Vision frames, Carl Zeiss vision has already subjected them to stringent quality testing using the most accurate instruments available. Zeiss Vision qualifies and validates each lens for:
- Cosmetic quality
- Power tests to ensure the proper prescription
Each lens is tested on a range of demanding environmental stress tests, including heat, humidity, UV radiation, and sand abrasion to ensure uncompromising durability. Here at IVI, we are consistently providing you with the highest quality lenses possible for your eyes.
Zeiss also understands that everyone’s eyes are very different. When designing a lens it is important to calculate the location of the center of the eye as it rotates to maximize the fields of clear vision. Standard progressive lenses often assume that every eyeball has the same length. ZEISS Progressive Individual® 2 utilizes proprietary Center of Rotation Evaluation (C.O.R.E.) technology to provide a more accurate calculation of the lens design. Based on extensive vision research and anatomical measurements of actual eyeglass wearers, the C.O.R.E. algorithm estimates the center of rotation to within 1mm for 99% of wearers. The result is superior visual clarity over more of the lens — without any requirement for additional measurements.
Now, what does all this mean? Purchasing our luxury designer sunglasses guarantees superior performance in optics for the best final result. What’s the proof? Hold your frames up to the light and check out the laser-etched Zeiss verification. The semi-visible ‘Z’ engraved onto each lens certifies the conformity to the highly restrictive standards, which introduced market parameters and procedures in abrasion, optical, and durability testing.
ZEISS vision has dedicated themselves to better vision, bringing their vast optical experience to every pair of precision lenses they manufacture for your pair of IVI sunglasses. We are proud to provide the best lens for both men and women, and we wouldn’t want anything less for you and your eyes. At ZEISS and IVI Quality is not just a word, it’s a way of life.
IVI Vision also offers blue light lenses for our popular optical frames and polarized lenses. Check out our blog posts to learn more about the benefits of these lenses.
