- Easy adaptation
- Wide and sharp vision at any distance
- Natural and accessible near vision
- Good, custom fit for both hyperopes and myopes
- Freedom in frame selection
- Flatter, more cosmetically appealing lenses without compromising optical performance
Customised progression lengths
Myopes move their eyes less than hyperopes to obtain the same visual field. They use a smaller part of the lens for the same object field. They need good long-distance vision and quick access to broad near visual fields.
Hyperopes move their eyes more than myopes to obtain the same visual field. They use a wider part of the lens for the same object field. They are looking for sharp, immediate vision at all distances.
The Ovation® lens design is personalised according to the visual requirements of each wearer type by taking into consideration vertical and horizontal prismatic effects (FV Power + addition). Ovation® offers three specific models designed for different types of ametropia.
Overall progression length of Ovation® is shorter than typical progressives’, ensuring a perfect fit for any frame.Design differentiated according to the ametropia
Due to 3 different progression lengths applied to the Ovation design:
- The myope is easily able to access near vision, without any field restrictions
- The slight ametrope regains good near vision while still preserving natural eye movement
- The hypermetrope has to make no particular effort to see well at all distances.
Customised near vision decentration
Hyperopic and myopic patients need different near- vision decentration to accommodate the lateral prismatic effect of plus and minus progressive lenses.
With a plus lens, light from a near object is converged or deviated laterally toward the base or centre of the lens, causing the wearer’s eyes to converge more in a corrective lens.
With a minus lens, light from a near object is diverged or deviated laterally toward the base or edge of the lens, causing the wearer’s eyes to converge less in a corrective lens.
To compensate for both situations, Ovation® lenses have customised near vision decentration to match the wearer’s gaze by prescription - more for hyperopic patients and less for myopic patients. Natural convergence is maintained.
￼Short progression lengths fit all frames
Due to its short progression length associated with exceptional softness, Ovation® can be used with small or large frames, while still respecting each wearer’s visual comfort.
In a small frame, Ovation® offers myopes and slight ametropes a short progressive length associated with exceptional softness.
