Harmonix™ Technology is a patented technology which employs a biometric model to determine the patient's eye shape data from their prescription.
The anatomy of the eye has a significant impact on the refractive state. Occular length can vary from one eye to another by as much as 20.5mm to 28mm, or 30% in height (emmetropic eye without visual defect).
Many progressive lenses only take prescription into account when calculating lens power at the distant vision point.
Harmonix™ Technology goes further by taking into account the entire eye anatomy – eye size, shape, and position of its centre of rotation.
Wearers will enjoy a wider and more comfortable visual space.
Principle of Eye Length
It is well known that the anatomy of the eye has a significant impact on the refractive state.
Occular length can vary from one eye to another by as much as 20.5mm to 28mm, or a height of 30% in emmetropic eye (without visual defect).
Today's conventional progressive lenses only take prescription into account when calculating lens power at the distant vision point.
Harmonix Technology goes further by taking into account the entire eye anatomy.
HARMONIX™ Technology & the Anatomy of the Eye
Low Ammetropes (Medium eye)
The eye shape is generally spherical. A progressive lens that strikes a balance between wide visual fields and smooth power gradients is desirable.
Harmonix™ Technology provides the best balance between wide fields of vision and smooth gradients
Myopes (Long eye)
The eye shape is elongated resulting in a steeper curved retina. A progressive lens with wider zones of sharp focus is desired.
Harmonix™ Technology delivers up to *12% wider fields of vision compared to a standard progressive lens.
Hyperopes (Short eye)
The eye shape is more compact which increases the sensitivity to visual aberrations. A progressive design in which the power changes are softer is needed.
Harmonix™ Technology manages power changes offering up to **17% softer gradients compared to a standards progressive lens (1).
It is important to account for the frame’s influence on the presbyope’s visual experience because it is the frame that determines:
- The visual space available for execution of the progressive design
- The position of the lens relative to the eye
Frame Optimisation™ Technology provides the best possible optical performance by taking frame parameters into account.
Wearers enjoy optimised visual zones and maximised visual performance in their choice of frame.
The widths of the visual fields are optimised based on the pupillary distance and the frame’s A dimension, bridge length, and shape (oval, rectangle, etc).
Vertical positioning of the visual zones (ie. progressive corridor length) is determined according to fitting height, B dimension, and frame shape. The result is an enhanced vertical viewing space and improved acuity for the wearer – even with shorter frame heights.
Dual Sided Digital Surfacing Technology
Extremely precise dual sided digital surfacing offers the greatest level of customisation and delivers significantly improved visual performance.
