The design is further enhanced, when desired, by a complete set of individualization parameters that take into consideration the unique attributes of the frame and the preferences of the wearer. If no parameters are provided, IOT Digital Ray-Path 2 will utilize default values.
Lens power differs from prescribed power. The design is calculated, point by point, to ensure wearers perceive the proper power when looking through their lenses at every distance and direction of gaze, including near distances for viewing electronic devices.
STRICT CONTROL OF MEAN POWER IN DISTANCE AREA OF THE LENS
Significantly reduces mean power error.
OPTIMIZED FOR ACCOMMODATIVE OBJECT SPACE
IOT Digital Ray-Path 2 incorporates the intelligent use of the wearer’s accommodation into the traditional calculations for reducing oblique aberrations, resulting in a superior personalized lens. Oblique aberrations are minimized more effectively than ever before.
The perceived power distribution remains stable, regardless of the prescription or base curve. This is especially beneficial for high prescriptions and large or wrapped frames.
PRESCRIPTION & ADDITION
Digital Ray-Path calculates the power that the user will truly perceive once the lenses are fitted on the frame.
This is the angle in the vertical plane between the optical axis of a spectacle lens and the sual axis of the eye in primary position.
Is defined as the distance
from the axis of symmetry of
the face to the center of the
Is the vertical distance between the pupil center and the deepest part of the lens shape.
BACK VERTEX DISTANCE
Distance between the cornea and the back surface of the lens.
Frame dimensions are used to calculate the final diameter, thickness of the lens and improve the efficiency of the optimization.
NEAR WORKING DISTANCE
This is the distance from the
lens to the typical reading
position for the wearer.
