Currently, most people are increasingly adjusting their eyesight with contact lenses, viewing glasses as remnants of the past (they do not fit into the image and are uncomfortable to wear).
It is important to remember: when choosing contact lenses for regular wear, comfort and safety should be at the forefront.
New "Ciba Vision"
The company "Ciba Vision" created a unique series - contact lenses Air Optix Aqua. Using innovative material with a high degree of breathability, the manufacturer managed to achieve unique results: in comparison with most similar lenses from other manufacturers, these contact lenses have an oxygen bandwidth of 5 times higher.
Description and properties of lenses
These Air Optix Aqua contact lenses slide smoothly over the eyelid thanks to their smooth surface. And the thing is in a special fluid agent that is connected to it. This property provides convenience and comfort with direct use of lenses.
Available with only one universal radius of curvature. Due to the fact that the back surface of the lenses can adapt to the cornea of the eye, they are suitable for more than 80% of users.
Production Features
Plasma technology is used in the manufacture of lenses. The essence of this method is as follows: with the help of plasma, or more precisely, the flow of charged particles on the lens, its surface is protected even at the end of its life from contamination, such as cosmetic residues, protein and lipid deposits that make up the tear.
In addition, plasma surface polymerization increases the wettability of the lenses, and as a result - additional convenience when using.
Feature of the Aqua Moisture System
Air Optix Aqua's unique contact lenses have four components:
- A substance that lubricates the lens and provides increased control when worn.
- Lenses are made from a special modern material Lotrafilcon B, which contains more than 20% moisture. Hydrogel silicone allows you to retain fluid and prevent the lens from drying out quickly, which ensures that they can be used all day without eye discomfort.
- The surface of the lenses is polished in such a way that allows them to be used for a long time without the formation of lipids and protein accumulations.
- A high degree of air transmission allows both to protect the eyes from oxygen deficiency and to improve the condition of the cornea.
Types of lenses of the Aqua series
There are several types of Aqua series:
1. Air Optix Aqua soft contact lenses.
2. Multifocal. These are presbyopia-correcting Air Optix Aqua contact lenses.
3. NIGHT & DAY - for continuous wear (not only during the day, but also at night) for thirty days.

Which lens to choose
Making a choice between the presented models of the Aqua series, of course, only multifocal possess special properties, and here the choice is small. And if the problem of myopia / farsightedness is quite standard, then a number of questions arise: "Which lenses to choose? Wear mode: continuous or daytime? Which ones are more profitable: contact lenses of Air Optix Aqua 6 pcs. Or 3 pcs. In a package? Etc.
Wear classification
According to this classification, contact lenses are divided into the following types of wearing:
- daytime (DW) - must be removed at night;
- flexible (FW) - you can not remove up to two nights;
- prolonged (EW) - can be worn seven days continuously;
- long or continuous (CW) - continuously up to one month.
Many choose day wear lenses
Despite the huge variety of vision correction tools for completely different manufacturers, the timing and modes of wearing, most people are willing to put up with the inconvenience, namely, removing lenses at night, and choose their daytime use. This is due to a number of reasons: from the point of view of hygiene, lenses need to be moistened and disinfected: by placing them daily in a container with a special solution, this way they are wetted and cleaned and, accordingly, the risk of accumulation of lipid sediments of tear fluid, protein deposits, cosmetics, etc. And as a result, the possibility of eye infection is reduced.
The experts who advise using contact lenses of the day mode, and continuous one only in case of need and in the absence of contraindications, are in solidarity with them and hold the same opinion.
The results of some medical studies prove that when wearing lenses continuously for a year, the probability of getting microbial keratitis is 0.18%, and the decrease in visual acuity is less than 0.04%, which is higher than the parameters typical for daytime lenses.
More details on the findings of research data from various scientific organizations can be found in the table below.
However, it is important to note: continuous use of daytime lenses can cause great harm to the eyes. Not only is the gas throughput of such lenses lower, and the eyes simply do not receive enough oxygen, and the following diseases are also possible: infection and neovascularization of the cornea of the eye (blood vessels grow into the cornea and spread to proteins).
The exception in this case is Air Optix Aqua contact lenses, the unique manufacturing technology of which ensures both comfort and safety during prolonged wear (they do not have a negative effect on the eyes during the entire period of their use). The only thing you need to consider is that the period of their use is reduced.
Therefore, it is necessary to follow the instructions for use and save, choosing a larger number of lenses in the box, for example, contact lenses Air Optix Aqua (6 lenses in a package) - it turns out many times cheaper.
In any case, there are people who, due to necessity, are forced to use a long lens wear routine, for example, truckers. Since, by virtue of their profession, they do not always have the opportunity to provide sterile lens care conditions. Often these contact lenses are recommended to users for therapeutic purposes (like bandage after corneal surgery).
Here the recommendation may be one - to choose the lenses of the corresponding mode. Otherwise, this can lead to a hypoxic complication of the cornea (due to its constant “oxygen starvation”).
The choice is yours
Today, the contact lens industry has gone far ahead and is able to offer users a huge selection. Of course, it is impossible to be 100% sure of the convenience and comfort of the selected options for the first time, and it is practically impossible to find real reviews on the Internet for Air Optix Aqua contact lenses.
Nevertheless, an analysis of the ratings of several sites selling ophthalmology products showed that Ciba Vision lenses are among the ten most popular.
It is important to note that contact lenses are a purely individual thing! Therefore, it is necessary by trial and error to find exactly your ideal means of vision correction. It may be possible to pick it up right away, but it may take more than one month.
