Review of multifocal lenses

The human eye is a complex optical system that consists of several lenses. With the years the aging process begin to  have a negative impact on all the structures of eyeball, including crystalline lens. Gradually, it's nucleus is thickened and lose the capacity of accommodation.

This process significantly reduces the visual acuity and becomes the cause of age-related farsightedness or presbyopia.



The person who suffers from this refractive error can not see close objects clearly. With time his (or her) crystalline lens completely lose an ability to change it's curvature. Finally the person has to use two pairs of eyeglasses – for close and distant vision. You must admit that it is not comfortable and aesthetically beautiful. That is why more and more people, that suffer from presbyopia, give their preference to contact lenses Air Optix Aqua Multifocal.

They were designed by CIBA Vision company for correction of age-related farsightedness. The unique peculiarity of these lenses is in presence of several focusing areas:

  • The peripheral area provides clear distant vision;

  • The transitional area allows to change focus between close and distant objects and to see clearly at average distances;

  • The central area provides excellent acuity of close vision. Thanks to this area people with presbyopia can enjoy their favourite activities without any difficulties.

These three areas fluently pass into each other and ensure qualitative vision at any distances. With contact lenses Air Optix Aqua Multifocal you will no longer have to wear bulky eyeglasses with bifocal lenses or constantly change eyeglasses with positive lenses depending on your activity.

Contact lenses Air Optix Aqua Multifocal are available with three values of optical power:

  • High – over +2,0;

  • Medium - from +1,25 to +2,0;

  • Low – up to +1,0.

The aspherical design of the inner surface of these lenses provides their correct centering and ensures high quality of vision even in low light conditions (for example at twilight).



Air Optix Aqua Multifocal are manufactured of silicone-hydrogel material, that is called as Lotrafilcon B. It's high water content and low coefficient of friction reduce the chance of developing the symptoms of eye dryness or irritation. In addition, these contacts are not felt on eyes because of their thin and delicate structure.

Contact lenses Air Optix Aqua Multifocal can be worn in two different schedules. Daily wearing schedule requires monthly replacement and constant care with the help of peroxide or multi-purpose solutions. You can start using these contact lenses in extended schedule with the permission of professional ophthalmologist. In this case lenses are worn for a week without removing and then replaced with a new pair. This schedule of wearing of lenses Air Optix Aqua Multifocal becomes possible because of their material, that has an excellent index of oxygen permeability. The transmission coefficient of oxygen of these lenses is 138. It's a rather high index, that ensures the complete absence of risk of hypoxic damage of corneal membrane (under condition of correct use).

For the convenience of use lenses Air Optix Aqua Multifocal are slightly tinted in light blue colour, that do not change your natural eye colour.

These contact lenses are a perfect choice for people with active lifestyle. They are absolutely safe for your health – in contrast to ordinary eyeglasses they can not break and injure delicate eye tissues. That is why contact lenses Air Optix Aqua Multifocal can be worn even when doing contact or extreme sports.

Not so long ago, contact lenses were not really popular in people with presbyopia. But together with the process of aging of the population, that is observed all over the world, the number of elderly people, that suffer from this eye disease, is constantly growing. For this reason all leading companies in the market of means of eyesight correction currently produce their own models of multifocal lenses.

For example, Johnson & Johnson company has expanded Acuvue series with multifocal lenses, manufactured of silicone-hydrogel material - Acuvue Oasys for presbyopia. The material of these lenses has a low coefficient of friction and high moisture content. Thanks to these properties contact lenses Acuvue Oasys for presbyopia can be worn even by people with sensitive eyes.

Bausch & Lomb company produce contact lenses Pure Vision Multi-Focal for the correction of presbyopia. They have high level of oxygen permeability and low index of dehydration.

The greatest variety of multifocal contact lenses are manufactured by Cooper Vision company. It includes lenses:

Large assortment of products allows to select the most suitable contact lenses for every person.



In recent years, the demand for disposable medical and hygienic products has significantly increased. Contact lenses have not become the exception to this general trend. All leading manufacturers today produce disposable daily lenses. For example, Sauflon company has developed the world's first multifocal contact lenses Clariti 1 Day Multifocal. They have all the advantages of disposable daily lenses and ensure qualitative and safe eyesight to people with presbyopia. A higher price is probably the only disadvantage of these contacts.

The assortment of multifocal lenses is great, and so it is rather difficult to select the most suitable of them.
