The bulk of information from the outside world( more than 80%) comes to us through the eyes. Perception, which provides the human eye, allows the brain to evaluate all the characteristics of the object in question - volume, size, color scale. Deterioration of vision, it can be said, significantly worsens the quality of human life.

Until recently, the only opportunity( not surgical) to improve their eyesight were glasses. Today, ophthalmologists increasingly offer their patients to abandon this optical device in favor of such innovations as lenses( for 1 month, for a quarter, for 2 weeks, for a day - lots of options).

Appointment of lenses and materials for their manufacture

Depending on the objectives pursued, the ophthalmologist will, after careful examination, offer the best option for each individual patient. If a person just wants to look attractive, have an expressive look, then color lenses will do. For a month, for 3 months, for a day - almost everyone can change the appearance or make a certain zest in the image.

If the patient suffers from nearsightedness or farsightedness and wants to eliminate these visual impairments, spherical or aspherical lenses are ideal for such a case. The first image quality is somewhat inferior to the second one, in which the optical power at all sites is the same. For those suffering from myopia and hypermetropia, this is the most correct decision. lenses for a month which is better

Myopia and hypermetropia, accompanied by astigmatism( disruption of the lens or cornea), can be corrected by toric contact lenses. How many lenses can I wear? For a month you will appoint them, for 2 weeks or for another period of time - this will be decided by the attending ophthalmologist.

In addition, the modern medical market can offer patients and means for correcting presbyopia( senile vision).The essence of the problem lies in the anomaly of the refraction of the eye, in which a person can not read text written in small print, or consider any small objects at close range. The most likely causes of the disease are a decrease in the elasticity of the lens, a change in its curvature, a weakening of the ciliary muscle that controls the focus.

Materials from which contact lenses are made( for a month or for any other period) are a hydrogel or a silicone hydrogel. The second composition has more attractive qualities for consumers: it is better to "breathe", does not need such intense moistening as a hydrogel. As a consequence, patients with contact correction from silicone hydrogel feel much more comfortable.

Replacement frequency, possible modes of lens wear

The term replacement frequency means the maximum period of wearing time of the correction means recommended by the manufacturer. After this lapse of time, the lenses must be replaced with new ones. According to this parameter they can be subdivided into:

  • contact lenses of one-day wearing,
  • ones that can be worn for 1 to 2 weeks,
  • contact lenses for a month( without removing, they can be used up to 30 days),
  • is also "optics"long wearing: from 3 months to 6 months and traditional lenses, which can be used for 1 year.

Contact lenses, serving from 6 to 12 months, are packed in special vials.

For more frequent replacement, they are often packaged in blisters. how much you can wear a lens for a month

Under the mode of wearing is understood the maximum time period during which the means for correcting the vision can not be removed. So, one group of lenses is designed for daytime use( dressed in the morning and taken off in the evening).The second includes prolonged funds( dressed for a week and not taken off at night).Flexible wearing mode means 1-2 days of use( without removing).Continuous use is when assigning lenses for a month. Without removing, they can be worn for 30 days. True, this is possible only with the use of certain types of silicone-hydrogel models, and they can only be used after consultation with an ophthalmologist.

Breathable contact vision correction

Contact lenses have a lot of different characteristics. Among all the others on the package of contact correction correction of any manufacturer there is a marking Dk / t. Dk is the oxygen permeability, t is the thickness of the lens at its central point. The ratio of these parameters to each other is called the transmittance of oxygen. For hydrogel lenses, this figure is 20-40 units, while for silicone hydrogel lenses it can vary from 70 to 170 units. Therefore, means of contact correction, made of silicone hydrogel, may well be called "Breathable lenses"( for a month, a quarter, two weeks or one day - it does not matter).lenses breathing for a month

Oxygen in such correction means is carried by a silicone component, which can be considered as a kind of silicone pump. The amount of liquid in such lenses does not play such an important role as in simple hydrogel ones, where the oxygen permeability depends on the volume of water( more water - higher permeability).Therefore, when solving the problem( if the lenses are chosen for a month): "Which are better - hydrogel or silicone-hydrogel?"preference should be given to the latter.

Advantages of a monthly replacement lens

Lenses for a month( which are better - will be discussed below) are widely used by consumers. The advantages of these means for correcting vision in front of models with different wearing regimes are the following:

- the duration of socks, the perfect combination of convenience and price;

- contact lenses for a month are produced in a wide range of optical power( from + 6.0 to - 12.0 diopters), which allows to cover a large group of consumers;

- the products are manufactured with a variety of characteristics and properties: "breathing", moisturizing, with insufficient moisture of the cornea, with increased biocompatibility, for use in low light conditions, with low scale formation, etc.;

- special lenses are developed for 1 month for astigmatism sufferers( multifocal);

- consumers are offered toning and color changing( color) lenses for a month, which can be either with diopters or intended for people with normal vision( zero).contact lenses for a month which is better

Using contact lenses( per month)

Here it is worth considering two options. The first - lenses with a day mode of wearing. These funds must be removed at night and stored in a special solution. During the night sleep, the eyes relax, and the lenses will be sufficiently moistened, will undergo special treatment( disinfection), and will be cleaned of various deposits accumulated during the day. Such lenses for the month of reviews have the most positive, but we must remember that special solution and storage containers are mandatory conditions, if non-observance of which there is a risk of damage to the surface of the product, contamination. As a consequence, inflammatory processes of the eyes take place.

How to wear lenses( for a month - the standard term of appointment), if they are prolonged or continuous use? There are also some nuances here. Such tools for vision correction are not removed at night, but not all models can be worn continuously for 30 days. Some manufacturers answer the question of how much you can wear a lens for a month, in the sense that they can not be removed within 6 days. Then for one night they are put in a special solution for cleaning. Yes, and the eyes during this time will rest.

However, modern technology is such that it was possible to develop and such lenses that can not be removed during the whole month. After this period they are simply thrown out, replacing them with new ones. For such models, you may not even need a special solution. Of the most popular products today are the following: Air Optix Night &Day, PureVision, PureVision 2 HD.

Information on how much you can wear a lens for a month, without removing them at night, the manufacturer usually places on the package.

And now let's talk about what products are most in demand.

Leading lenses designed for use during the month( afternoon only)

There is such a thing as the leaders-lenses for a month. Which are better? High consumer demand is enjoyed by products called MaximaSiHyPlus. Of all the existing options, designed for a monthly replacement with removal for the night, these products are some of the best. The material from which they are made is the last generation silicone hydrogel. Good humidification, high oxygen transmittance, sediment resistance and biocompatibility provide the eye with the most comfortable conditions.

Another model of contact lenses popular with the population is PureVision 2 HD.Of all the products manufactured to date, they are the thinnest. The high transmittance of oxygen( this is a kind of "lenses breathing" for a month) allows you to wear them for a week without removing. PureVision 2 HD provides clear visual perception, even in poor light conditions, and the eyes do not suffer from discomfort.

An excellent level of comfort is provided by the person of "Akuyev" lenses( for a month).To produce them, modern materials are used. A clear picture when working on a computer, watching TV, while in a room with dry air, excellent air permeability guarantee comfort and safety to the eye.

Best models for long wearing

Among the models intended for continuous use, there are their leaders - contact lenses for a month. Which are better? The product of Air Optix Night &Day Aqua. The material used to make them is silicone hydrogel. The optimum level of moisture content and high air permeability ensure comfort to the eyes during the entire period of wearing.

Contact lenses Biofifnity( CooperVision) are also designed to be worn for a month( only in the afternoon) or for continuous use for 2 weeks. Silicone hydrogel, from which they are made, has optimal parameters of air permeability and moisture content, which provides the eye with safety and comfort during the whole period of operation.

Contact lenses "Akuyev"

One of the most popular on the medical market of vision correction means not surgically - lenses "Akuyev Oasis".For a month they, in general, are not calculated. The unique technology by which lenses are made combines two important aspects that protect the eye from inflammatory processes: moisturizing and continuous saturation with oxygen.

It's no secret that now many suffer from the "dry" eye syndrome, the reasons for the development of which are rooms with low humidity, a long sitting at the computer, in front of both the TV, etc. Previously, an ophthalmologist could not pick up contact lenses for a patient with such a disease. Today the question is solved simply. Lenses "Akuyev"( for a month they are not intended, and even without replacement, but two weeks - quite an acceptable period) are made with a special moisturizing component that continuously saturates the eyes with moisture. Although there are consumers who wear such lenses for a month, always taking pictures at night. By the end of 4 weeks, the product may become a bit cloudy( or it may remain transparent).

lenses for a month

Many patients find daily contact lenses 1 Day ACUVUE TruEye one of the most comfortable. To produce them, silicone hydrogel is used( usually hydrogel is used for one-day use).The oxygen permeability of these contact eyesight correcting means is 100%.These lenses are so convenient that they allow a person to forget "about their presence".

The degree of oxygen permeability in these eyesight contact correction products is significantly higher than that which is considered the norm for all others. Lenses "Akuyev Oasis"( for a month at least two sets are needed) are equipped with a first class UV filter, which reliably protects the retina and lens from B-emissions( almost 100%) and from A-rays( up to 96%).

"Akuyev Oasis"( for two weeks) or any contact lenses for a month( which is better for the consumer and the doctor) should be taken with you when you go on holiday.

Quarterly lenses

Quarterly lenses( for 3 months) reviews of ophthalmologists and consumers are not considered the best option for contact correction of vision. Means of such a prolonged wearing require appropriate attention( it is a very careful care).Today, people increasingly prefer lenses with a short life( as more modern and comfortable, made of the latest materials).

Adherents of the same means of vision correction with a long period of wearing can recommend the product Precision UV( CIBA Vision Corp).The material used for their production( hydrogel), blocks up to 91% of harmful to the eye UV radiation. Such contact lenses are the best option for those who lead a rapid lifestyle and do not always have the ability to remove attachments.

Opinion of consumers and specialists-ophthalmologists

So, can I wear and wear lenses for a month without removing? Reviews of ophthalmologists on this score are mostly positive. If the correction tools are selected by a specialist taking into account the state of the patient's eyes, they can be worn for 30 days, but remember the date of scheduled replacement and give your eyes to rest at least one night. In the morning, you can safely wear a new set of long-use contact lenses. However, if the patient feels uncomfortable, the lenses should be removed immediately and consult a specialist.

As far as consumers are concerned, the vast majority of people are quite effective in these contact vision correction aids. Lenses( any - one-day, weekly, monthly, quarterly, etc.) are almost invisible from the outside, and the vision becomes much sharper than with glasses. To look away, the "ochkarik" has to turn his head, and a man with lenses has to squint his eyes. Unlike glasses, the lenses do not fall out during sudden movements and do not sweat when the ambient temperature changes suddenly. And in general, a person with lenses is available to any kind of sport, outdoor activities, etc.

Cons, of course, also have a place to be. Consumers say( and ophthalmologists confirm this), that if contact lenses are picked up incorrectly, eye irritation can begin, and sometimes vision may deteriorate. In addition, a small percentage of people have a very sensitive cornea. Such consumers simply can not wear contact lenses, and they have to be content with glasses. However, this syndrome is rare. The majority of people who use contact lenses are very satisfied with the results from the application.

Well, that's all. Finally, let's remind: if the need to replace glasses with contact lenses is over, the main thing is to turn to a good ophthalmologist who will evaluate all the pros and cons and give appropriate recommendations.
