Custom-fit for virtually every prescription
Ovation® lenses use custom-fit progressive lens technology by
wearer type to easily change progression length and near-vision
decentration to better match the needs of both hyperopic and
myopic patients. Ovation lenses deliver clear, seamless
vision for every wearer; whether farsighted or nearsighted. A true aspheric lens, Ovation provides great looks
combined with a flatter lens profile and the comfort of thinner,
lighter materials |

Customized progression lengths.
Near and farsighted patients need different progression
lengths to accommodate the vertical prismatic effect of plus and
minus lenses. |
.
With a plus lens, light from a
near object is converged or deviated upward toward the base or
center of the lens, displacing the object lower in the lens.
With a minus lens, light from a near object is diverged or
deviated downward toward the base or edge of the lens,
displacing the object higher in the lens.
To compensate
for both situations, Ovation lenses feature customized
progression lengths to match the wearer’s gaze by prescription —
longer for hyperopic patients and shorter for myopic wearers.
The vertical prismatic impact of plus and minus lenses
causes hyperopic and myopic wearers to rotate their eyes
differently when reading. Ovation lenses allow the optimal
length of the power progression to be customized by wearer type
depending on the strength of the prescription. |

Customized near-vision decentration.
Near and farsighted patients need different near-vision
decentration to accommodate the vertical prismatic effect of
plus and minus lenses. |
With a plus lens, light from a near
object is converged or deviated laterally toward the base or
center of the lens, causing the 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 eyes to converge less in a corrective
lens.
To compensate for both situations, Ovation lenses
have customized near-vision decentration designed to match the
wearer’s gaze by prescription - more for hyperopic patients and
less for myopic patients.
The lateral prismatic impact of
plus and minus lenses causes hyperopic and myopic wearers' eyes
to converge and diverge differently when reading. Ovation lenses
provide decentration of the power progression to be customized
based on the strength of one's prescription. |
