All progressive lenses have always had two distorted lateral zones that are not visually effective and cause the unwanted swim effect. These lateral zones causes a peripheral power error from both cylindrical and spherical error components.
EyoGraph has been developed by applying the latest innovation in lens design methodology which utilizes a strict control of the spherical power. As a result, the spherical power errors at the periphery tends to be zero, significantly reducing the lateral distortion and swim effect.
EyoGraph is ideal for all progressive lens wearers, experts or novices, looking for a premium progressive lens that offers both extended visual fields and minimal lateral distortion.
Thanks to its unique Curvet CX technology and the optimized back surface designs.
The diagram below compares the two- lens thickness profile of the same prescriptions.
The Left is a regular Progressive lens, and the right is EyoGraph Progressive.
With Curvet CX Technology, it is possible to produce plus progressive lenses from flatter and better-look and increased visual acuity for all distances
The Curvet CX Technology has a unique front surface with a variable geometric design, which means the power of the front surface increases continuously from top to bottom and this helps in reducing the oblique aberrations in the lens. The patient will notice an expanded reading zones with improved peripheral vision. Curvet CX Technology is combined with a sophistication and optimized digital design on the back surface.
SteadFast Technology uses a strict control of the mean power that practically eliminates the spherical error in the lateral areas of the lens. Thanks to this improvement, a significant reduction of the maximum astigmatism lobes is achieved, offering the wearer an improved lateral vision with superior image stability.
