Many do not know that there are contact lenses that can be progressive, ie lenses that can correct vision and far and near. Most commonly, people over 40 years of age require the use of devices to correct for near vision. Wearing special glasses for distance and special glasses for near and not so easy, because the need to constantly removing and putting the appropriate glasses. Also, several pairs of glasses are not the best solution for people who lead an active life or for those who do sports. Therefore, multifocal contact lenses are the right choice for many of the world's population exceeds 40 th year.

Some types of multifocal lenses have bifocal design or perform vision correction in two fields - field for near and far field. The new generation of multifocal lenses has design, similar to progressive lenses used for spectacles or have three fields - field close to center distance and far and provide excellent vision correction through natural and smooth transition between all fields.

As with a single vision lenses and multifocal lenses exist in different types: Semi-hard, gas-permeable and soft lenses, and according to the duration can be daily, monthly and yearly. Unlike the past, when soft multifocal lenses could correct only field, today there is choice of multifocal lenses that can successfully correct the occurrence of astigmatism.

According to the design, multifocal lenses can have:

Concentric bifocal design - where the share of close is marked with a small circle in the middle of the lens, surrounded by considerably larger circle which corrects for diopter away.

Aspheric design - available only in gas permeable lenses, where the upper is for diopter correction for far, and lower diopter correction to close. The two sections are separated by almost invisible line between them. Because of the division only two fields, these lenses are used most often when driving and reading.

Simultaneous Design - the two fields to close and away, are located in front of the pupil before. This means that the brain must move part of the lens to emphasize and which to ignore in order to provide a clear picture.
