Freeform® is a nice buzz-word we like to use when referencing the latest in digital lens technology. The concept refers to any lens that is surfaced without the use of hard laps or refers to the digital process itself. Producing a lens in this manner does not magically make it any better for the user. This technology does provide the possibility of unprecedented freedom of design and superior optical properties. What makes a “freeform®” lens better is the customization and enhancements that are calculated by the design software. Sadly, most lenses that are offered today still do not take advantage of this technology. At CLS we have the most advanced progressive designs available, with auto- custom features as well as manually input variables to ensure that you offer only the best to your customers. All of our products are designed, maintained, and updated regularly by a major supplier. (Due to proprietary processing and customization we choose to not reveal our source, however you can be assured that you are not getting “generic” or “no-name” unproven products from us. We offer only the best designs, using only the best software to give you proven, successful, superior lenses. )
Here is what we offer:
CLS Basic: an entry level “freeform” lens. It is 100% backside progressive but has no additional enhancements.
CLS Advantage: the best choice for most PAL wearers. These lenses are made with user-power calculations, ensuring that the wearer gets exactly what the Dr. ordered. (Traditional lenses are made with measured power calculations, meaning the lensmeter reads it correctly, but for the patient there is always an “adaptation period”. ) The Advantage has custom progressive channel width, length, and inset per pair of glasses. These calculations are based on PD, seg height, RX type, frame shape, and lens design. No additional PAL measurements are required.
CLS Ultra: a more complex version of our Advantage. With all the features of the Advantage, the Ultra is a more tailored lens. We require a true “as-worn” pantoscopic angle, vertex distance, and measured frame curve. All adjustments must be made before these measurements are taken, and the frame must remain in adjustment in order to take full advantage of this lens design. Wearers of these lenses may require frequent adjustments depending on their lifestyle and activities. Due to the full-customization and precise measurements, fitting, and wear position required, we rarely recommend the Ultra.
CLS Reader: a digital “office” or “computer” lens. Made with the same features as our Advantage, but designed similarly to “office” lenses and “computer” lenses.
CLS AF: a pre-presbyopia lens designed to ease the fatigue caused by SV wearers who read or use computers a lot. This is also for SV wearers who are not quite ready to admit to needing a bifocal but do need “a little help with small things up close”.
CLS SV: digitally-enhanced SV lenses. We can use auto-generated custom variables to calculate these, but they work better with true as-worn measurements: pantoscopic tilt, face-form curve, and vertex distance.
