The multi-purpose freeform single vision design that takes advantage of digital enhancements.
Perfecta Single Vision digital lens takes advantage of our in-depth knowledge in personalized ophthalmic lens design. The Perfecta Single Vision design has been engineered for peak optical performance regardless of the frame style or lens material in most prescriptions.
Lenticularization is a process developed to minimize the edge thickness of a lens. The lab defines an optimal region around the fitting cross; outside this region the software reduces the thickness with a gradual change in curvature, resulting in a thinner lens.
The graph above 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 Perfecta Single Vision lens for high prescriptions is 76% more stable than a conventional lens. Bottom line - patients with a higher prescription have a much larger "sweet spot" for clear vision.
