IOT Single Vision design,the multipurpose design that calculates any type of single vision lens

IOT's Advanced Single Vision takes advantage of our in-depth knowledge in personalized ophthalmic lens design to launch a new and multipurpose Single Vision product. The IOT designers have engineered a Single Vision design with capacity to produce any type of Single Vision free-form lens, no matter the frame, material, base curve or prescription. This includes Standard Single Vision lenses, including complicated cases such as high prescription or lenses optimized for wrap frames. IOT Single Vision design can produce any type of Single Vision lenses.

HD wrap around Single Vision lenses

Wrap around single vision lenses calculated with IOT Single Vision design improve the field of accurate or HD vision. Notice the difference between a conventional or a free-form non-optimized Single Vision Wrap lens and the IOT Single Vision or HD Wrap lens. For the conventional lens, the pupil has an error of 0.25D. The IOT SV lens provides the wearer with accurate power in pupil and almost any viewing direction.

HD for high prescriptions, notice the difference

The graph to the right shows the importance of oblique errors for a single vision lens of -4.00 diopters. The horizontal axis represents the distance from pupil cross to the part of the lens which is being used when looking in gaze directions. The IOT Single Vision lens for high prescription is 76% more stable than for a conventional lens.
