Superior image stability like never before
All progressive lenses have two distorted lateral zones that are not visually effective and result in the unwanted “swim effect.” These lateral zones cause a peripheral power error from both cylindrical and spherical error components.
Developed with cutting-edge innovation in lens design methodology, EyoGraph utilizes strict control of spherical power. As a result, the spherical power errors at the periphery tend to be zero, significantly reducing lateral distortion and the “swim effect.”
EyoGraph is ideal for all progressive lens wearers, experts, or novices, looking for a premium progressive lens that offers extended visual fields and minimal lateral distortion.
EyoGraph is available in variable MFHs.
Curvet Technology enables flatter, better-looking plus progressive lenses with increased visual acuity at all distances. The diagram below shows the thickness profiles of two lenses with the same prescription.
The left shows a regular progressive lens, while the right shows EyoGraph progressive lens.
Curvet Technology possesses a unique front surface while retaining a variable geometric design. This means that the front surface’s power increases continuously from top to bottom, reducing oblique aberrations in the lens.
Users will also notice expanded reading zones with improved peripheral vision. What’s more, Curvet is associated with a sophisticated and optimized digital design on the back surface.
SteadFast Technology strictly controls the mean power that eliminates spherical error in the lens’s lateral areas. Thanks to this, maximum astigmatism lobes are significantly reduced, offering users improved lateral vision with superior image stability.
