Progressive series in freeform surface
The progressive lens in the free-form surface has a 30% larger field of view than the traditional progressive lens
The inner surface progressive lens surpasses the traditional progressive design.
For different wearers, the lens luminosity optimization calculation is performed according to the prescription luminosity, and the actual wearing effect of the progressive lens is simulated in advance, and then the program storage memor y is used for high-precision cutting processing to reduce the visual field distortion problem. Low, provide more excellent visual quality. Ever y piece of progressive lens that has been perfectly shaped has a comfortable and natural wide field of vision in the far, middle and near, and is easier to adapt, bringing an unparalleled visual experience to the wearer!
● A wider field of view: the wearer can obtain continuous clear vision from the far point to the near point through the progressive multifocal lens, and can see the far, middle and short distances clearly
● Dynamic vision is clearer : when the light moves from one area to another, the eye adjustment process is natural, and it will not cause dizziness and uncomfortable vision due to jump images
● Greater comfort: natural vision, in line with physiological optics, faster adaptation and shortening the adaptation period
● The appearance is more fashionable: the appearance is more beautiful than bifocals, there is no sub-film dividing line, and there is no annular blind zone
Look close and see far, one mirror for multiple uses, vision correction function, more comfortable to wear
Moving the progressive design to the inner surface significantly expands the field of view of each zone of the lens. Another factor that affects the field of view comes from the aspheric or astigmatic aspheric design of the rear surface. The aspheric design makes the radius of cur vature of the apex of the lens flat so that the lens can get closer to the eyeball, which is also an important factor in expanding the field of view.
Lens description
Adopt soft asymmetric design principle to meet the balance of far, middle and near
And the astigmatism area on both sides has been effectively improved to increase the lens field of view by 35%
It also makes the wearer feel comfortable in the transition of each light zone and easier to adapt.
