IOT Intelligence is the technology and innovation that powers the Camber lens excellence, from the unique variable curve front surface of the Camber blank to the strict lab enablement process. Let’s review the many technologies that result in the unique Camber lens. Camber Variable Base Curve: The Camber variable base curve blank improves the front surface profile that delivers each viewing zone a base curve matched to its function. The width of undistorted near vision is a major improvement over single vision front freeform progressive designs.

“The proof of the pudding is in the tasting” is an adage meaning that to determine success, put it to the test. While a lens design is impressive in theory, it must be put to the test with actual wearers with real-life use to be validated. Wearers judge lens performance based on personal comfort, not just acuity. Today’s screen-focused consumer has new vision needs and higher demands for comfort in their new work from home (WFH) environment. While other digital and web-based technologies rapidly adapt to our new reality, increasing our WFH comfort and productivity, so has lens technology.

Frame information plays an important role in cut out. I know we’ve all heard this phrase, but do we really know what it means? Cut out is exactly what it sounds like. Imagine you’ve rolled out some cookie dough, and you must determine how many cookies you can cut from that flat sheet of dough. Well, it depends on the size and shape of the cookie cutter. Using a smaller shape cookie cutter will result in more cookies.

Let’s start with a simple truth: Laboratories make better lenses if you can tell them everything you know about the patient’s frame and how it fits on their face. When I say everything, I mean everything. We understand the importance of providing box measurements to the lab, but these frame dimensions don’t tell the lab the shape of the frame eye wire. Let’s say that the frame is an aviator shape, but you don’t let the lab know this, so what could go wrong? The shape of the frame/lens affects both optics and cosmetics. We know the fitting height for progressive lenses should be measured from center pupil to the deepest part of the frame, but do we know why?

The sensation is an uncomfortable, unnatural feeling of unsteadiness for anyone who has experienced the “swim effect” when wearing and trying to adapt to progressive lenses. The wearer experiences a non-stable perception of surroundings. The swim effect causes discomfort and reduces overall lens satisfaction, making adaptation more difficult. Despite advancements in progressive lenses, some patients still experience this effect.

There are many steps in an ophthalmic lens journey, and each can impact lens optical quality and performance. It starts with precise refraction by the doctor utilizing calibrated equipment: next step, precision measurements taken by the optician/technician using calibrated instruments. With the first two steps fulfilled, the lab’s free-form surfacing generators apply the free-form design to the uncut lens blank.
