Visual performance incomparable with any other single vision lens
IOT’s Advanced Single Vision takes advantage of our in-depth knowledge in personalised ophthalmic lens design to reach the highest performance also for Single Vision lenses. The IOT designers have engineered a Single Vision design with capacity to produce any type of Single Vision freeform lens, no matter the frame, material, base curve or prescription.
Not only standard prescriptions to be fitted in common frames can be produced with this design, IOT Single Vision is also a high performance design for complicated jobs such as high prescription or lenses for wrap frames.
Thanks to Digital Ray-Path® each pair of Single Vision lenses are able to be calculated entering the real personalisation parameters or; when this data is not provided, to be calculated using default values for these parameters. Maximum performance can only be reached if they have all the real personalisation parameters. For frames without pronounced wrap angles the quality reached using default values will be close to the maximum one.
Digital Ray-Path® is an innovative calculation technology that uses a design engine to compensate the lens with a simulation of the binocular eye-lens system. Every unique lens is individually calculated guaranteeing an adapted solution for any prescription and base curve.
Conventional Single Vision lenses for high prescriptions have the weakness of losing visual clarity when looking in lateral directions. This inconvenience is caused by oblique astigmatism, and its correction is essential for providing clarity and comfort. With IOT Single vision design, people with high prescription will enjoy a notable improvement.
