Direct Lens Technology™ is Shamir Optical Industry’s latest technological development. A package consisting of hardware and software, it is sold to labs worldwide. Based on Freeform Technology, it represents the 21st century's new approach to lens processing – customized back surface optics. Direct Lens Technology™ combines the patient's data with a lens design based on Shamir’s Eye-Point Technology™ in order to create a personal file for a customized progressive lens with expanded vision zones, precision optical power and the most elegant lens shape. The lens surface data file is computed by Shamir's Freeform software and transferred to advanced cutting and polishing machinery for mold-free lens production. This unique process yields a finished lens containing individual characteristics. Direct Lens Technology™ Components Software Shamir's Prescriptor™ Freeform software is designed to manufacture progressive lenses according to specific prescriptions. Prescriptor™ calculates and prepares a progressive surface file. Taking into consideration all manufacturing aspects (e.g. geometric measurements of blanks, blocking tools, machining parameters, etc.), it follows up by sending the file to the lens generator, lens polisher and laser lens marking machines. Hardware Shamir makes sure that the lens surface file computed by Prescriptor is readable and suitable for lens processing by any one of the existing free-form machines available on the market at the present time and in the future. Eye-Point Technology™ Shamir Optical Industry's first technological breakthrough, Eye-Point Technology is a radical departure from conventional eyeglass lens analysis tools. Ensuring an accurate design and analysis, it enables the development and manufacturing of sophisticated, tailor-made progressive lenses. The key element behind Shamir's Eye-Point Technology is a dedicated ray-tracing program written by Shamir scientists. Combining lens surface topography data with a highly advanced mathematical algorithm, this sophisticated technology calculates the optical performance of thousands of locations covering the lens surface, taking into account the following parameters: - lens index refraction - lens prescription - lens center thickness - distance from the eye to the back vertex of the lens - distance from the lens to the object - object’s angular position in the eye’s field of vision - pantoscopic tilt of the frame - pupil distance - thickness reduction prism, and more.
