Basic ophthalmic lenses correct for near or farsightedness, where the focal point is in front of or behind the retina.The curve to adjust the focal point and let the light hits the retina precisely, so that people can focus.Other lenses may have additional features tailored to each case

What ophthalmic lenses do you need?
Depending on the type of visual deficiency you have, and always advised and informed by us you can choose between different types of lenses:
This type of ophthalmic lenses only corrects only from far and wide, not both simultaneously. This type of lens focuses vision at a distance, either near or far.
It is recommended for people who have good vision in one of the distances, whether near or far, but needs or for everyday tasks such as reading, working on computer, mobile etc. or longer distances as driving.
This type of bifocal lenses used to get a clear vision near and far. Before appear progressive lenses were used more frequently, but now put in fewer cases because progressive lenses have the advantage of a clear vision at different distances.
Besides the bifocal lens on the area it appears near the lens. There are fewer types of materials on these lenses, but if we can get them in mineral and organic.
The operation of the progressive lens was added based on an area where the gradient away begins to gradually change from the required gradient to look for different distances to reach the area near and to achieve it, on the side of the lens is blurry due to the induced deviation. According to the sides about the vision is lost there will be a progressive or others.
There are a number of progressive and we can say that the main feature to distinguish from each other is what we call “aisle view”, which is the field of view of the progressive lenses.
There are also progressive lenses specific to a particular job or eyeglass type (computer and customer service, for new or smaller design frames …).
We have VISIOFFICE, a new instrument for measuring all parameters required for the latest generation of progressive lenses from Varilux.
