A Different View Many people who wear glasses often find the level of clarity to be just short of perfect. This can create eye strain and make wearing glasses even more difficult. Shamir Canada has developed a balanced progressive lens holistically adapted to the patient’s prescription. The result is a clear and comfortable visual experience. “Like all of our lenses, Autograph III is a full back-side freeform lens.  The power range is very wide, with cylinder available up to -9.00 (this is quite rare) and the material choice in transitions and polarized is very deep, quite unique in the market,” said Martin Bell, National Sales and Marketing Manager for Shamir Canada. He notes the lens creates an image size that is closer to natural size, and is well balanced between plus and minus prescriptions. He says plus lenses will often give the wearer a magnified image but with a smaller field of view than with uncorrected eyes. To address this, Shamir has applied reverse engineering to its technology by defining the size of the object patients want to see and simulating real world images through EyePoint TechnologyIII. This provides improved viewing for all patients regardless of lens power and frame choice. “Image positions are different between a plus and minus lens.  This means that minus wearers usually have to look very low in the lens to read properly, and plus wearers have the near image displaced upward which can “cramp” their distance area,” he said. • See side bar on page 30 28 OPTICAL PRISM | MARCH 2014
