Advantages

 

Visual definition rivaled by no other
Single Vision lens

IOTís Advanced Single Vision takes advantage of our in-depth knowledge in personalized 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 free-form lens, no matter the frame, material, base curve or prescription.

Not only standard prescriptions to be mounted in common frames can be produced with this design, IOT Single Vision is also a high performance design for complicated jobs such as high prescriptions or lenses optimized for wrap frames. Thanks to Digital Ray-Path each pair of Single Vision lenses are able to be calculated entering the real personalization parameters or, when this data is not provided, to be calculated using default values for these parameters.

Maximum performance can be only reached if having all the real personalization parameters, but for frames without pronounced wrap angles the quality reached using default values will be close to the maximum one.

Target & Positioning

  • Ideal for everyone who need single vision correction. Specially beneficial for high minus and plus prescriptions or large astigmatic correction.
  • The best Single Vision totally compensated for each specific user.

High Definition in all gaze directions also for
high rescriptions

The graph to the right shows the importance of oblique errors for a single vision lens of -4.00 diopters, for a higher prescription the oblique errors are even higher. 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.

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 notice a notably improvement.
