When we see an object, slightly different images are seen in our two eyes because of different positions of each eye on the head. This is referred to as binocular disparity, from which Three-dimensional images and the distance from the scene are perceived by our brains.

But substantial aberrations may be found in the peripheral areas in spectacle lenses, which cause not only imperfect image quality, but also improper perception of three dimensional images and distance. This astigmatism is easily accompanied by eye strain and blurred vision.

So we have adapted the concept of DVO technology to the field of binocular vision. Peripheral zones are divided into numerous points and calculated on a point basis. This creates the expanded usable zones and will contribute to your better vision performance.
