Wavefront/ Free Form Wavefront/ Free Form TechnologyTechnology
A way to control the front side imperfections of a lens Allows patient to experience crisper vision in distance zone Typically allows intermediate zone to appear much wider Clearer vision as the eye moves across the lens
– Large, clear viewing zones free of unwanted power errors associated with lower-order aberrations
What Are Wavefront What Are Wavefront Aberrations?Aberrations?
“Wavefront aberrations” optical errors produced on
the front surface of a lens Wavefront aberrations are a natural consequence of the
changing curvature of a progressive lens– They can be controlled, but not eliminated
Semi-finished progressive lenses cannot address
wavefront aberrations of an individual’s eye

• Makes the patients Eyes appear less Magnified
• Improves the peripheral optics of the lenses

Improves wearers appearance
Eliminates unwanted light reflections or glare from entering the wearers eyes.
Allows from 8% to 15% more good light to enter the wearers eyes resulting in improved vision especially at night.

Visual demands of aging Visual demands of aging patientspatients60 year old eye needs 3 times more light to see than the
20 year old eye. (only 33 % of light reaches the photoreceptors)
Pupil size shrinks Pupil size
DAY NIGHT– 20 year old eye 4.7mm 8.0 mm– 60 year old eye 3.1mm 4.1mm
Lens becomes more opaque or cloudy –making the discrimination of blue colors more difficult
Adaptation of different lighting conditions slows down- mainly caused by glare at night
Motion perception slows- difficult to accurately judge fast and slow moving objects
Peripheral vision is impaired Contrast sensitivity during daylight is also an issue

If your EYES could talk to you!!
What would they say???
Transitions Lenses T.V. Commercial
Bright Light often affects Contrast Sensitivity
Tinted lenses in high-glare situationscan improve Contrast Sensitivity
Transitions Lenses Improve Contrast Sensitivity
• Contrast Sensitivity is the ability to distinguish between an object and the viewing background
Transitions VI: Advanced Performance
for Healthy Sight
Transitions VI Promotes Healthy Sight by:
• Reducing glare
• Improving contrast
• Reducing eye fatigue and eye strain
• Providing visual comfort
• Blocking 100% UVA & UVB
Transitions Lenses Better for the patient as compared to Clear Lenses
Transitions Lenses with AR
Clear Lenses
Polarized Lenses
Polarized Lenses for SAFETY
Polarized Lenses are needed by anyone who DRIVES during bright sunny conditions.
