In general, contact lens solution is used to take good care of your contact lens. Contact lenses are thin, finely crafted plastic discs designed to fit over the cornea of the eye, usually to correct vision problems caused by refractive error. They are held in place by a natural layer of tears on the surface of the eye.

In addition, contact lenses provide better peripheral vision and virtually eliminate the image distortion sometimes caused by eyeglasses. Contact lenses are now available for the correction of most vision problems caused by refractive defects of the eye including nearsightedness, farsightedness, astigmatism, and presbyopia.

There are several types of contact lenses- such as bifocal contact lenses, colored contact lenses, cosmetic contact lenses, disposable contact lenses and even custom contact lens.

Rinsing solution: After cleaning, lenses should be rinsed with a commercial saline contact lens solution.

Disinfecting solution: The disinfecting solution inhibits and/or kills bacteria and other harmful micro organisms on the lenses that can cause eye infections. After cleaning and rinsing lenses, they should be stored overnight in a storage case filled with fresh disinfecting solution.

Multipurpose solution: A combination solution designed to clean, rinse and disinfect contact lenses.

Rewetting solution: Drops that lubricate the lenses while they are being worn. They can be used all day to keep the eyes moist and to enhance the comfort of wearing contact lenses.

All solutions used for cleaning, rinsing, and disinfecting contact lenses should be discarded after the expiry date on the bottle. To avoid contact lenses dry eyes, always follow the opthalomogist’s recommendations for cleaning and caring for your lenses.

Except for contact lenses that are worn for a short, continuous period and then thrown away, all contact lenses require cleaning, disinfecting, and rinsing on a daily basis. In fact, a contact lens that has been removed from the eye should never be reinserted without cleaning and disinfecting. Never sleep in contact lenses unless approved by opthalomogist.

From children excellent users of contact lenses (КЛ) turn out. However for some reasons many doctors-kontaktologi fluctuate, appointing КЛ to children, and advise to parents not to give a lens to children while those will not reach teenage age. Thereby they render rather bad service both to the patients, and our trade as a whole. Is not present the uniform clinical reason on which the small child (and in the practice we select КЛ to children since 5 years) could not become very successful user КЛ and as a result to improve the sight.
Probably, as well as in a case with many other problems of optometry, business in isolation of the doctors protecting secrets of the speciality from general public. But why so much оптометристов feel anxiety, appointing КЛ to children? Because of fear to put to the child an irreparable harm? If so to them not followed work and with adults. From fear to cause to the child a pain? But why to children it should be sick, if not painfully adult? Or it is simple because they do not like to work with children? In that case, on their place for certain there will be a colleague who receives from it pleasure. To inspire большее number of doctors-kontaktologov for work with small patients, we bring to your attention following 10 substantive provisions that you could check up, how much they correspond to your practice.

1. It is necessary to understand, in what case contact correction of sight  can be more pertinent and useful.
The considerable part of children is elderly till 12 years starts to visit the ophthalmologist because of high , an astigmatism and анизометропии. In all similar cases the doctor aspires to appoint such means of correction that it worked whenever possible constantly and served as it is possible longer. However all of us we know that очковые frames bend, loosened that points often act in film also time most part roll without business. Transition on guarantees that the child will have all the day a stable, constant, correctly picked up correction. At any appointments from above 3 D (or from above 2 D for correction анизометропии), unsuccessfully chosen glasses will lead more likely to essential deterioration of sight that in turn will strengthen and will aggravate and will lead to deterioration of three-dimensional sight.
To children who love sports meets, transition from points on soft contact lenses gives the chance to receive where большее pleasure from game – and to achieve the best results thanks to the best three-dimensional sight and spatial orientation. Besides, it is obvious that to go in for sports in КЛ more safely, than with points on a nose, except for swimming and a ball game. In the latter case for the child and so it is much cheaper and more safe to carry usual goggles than to be spent for special goggles with optical correction. As to swimming it is one of few situations in which use is inadmissible, but on this case there are inexpensive and everywhere accessible points for swimming with dioptries.

2. Dealing with patients-children, plan long-term strategy.
Usually we try to select at first to children one-day lenses, that they have started to use without superfluous expenses and problems, which can arise at carrying of lenses of monthly replacement if casually to damage them at the very beginning of carrying. Whenever possible we aspire to that children and continued to carry one-day , instead of passed on monthly which it will be more difficult to them to look after.
However at high values of optical force exact correction it is possible to give only by means of КЛ, calculated on a month or on больший carrying term. In similar cases we sometimes begin with one-day КЛ, and in couple of weeks we translate the child on lenses of long carrying. Thus it is necessary to warn that visual acuity will a little decrease at the first stage, to transition to “definitive” correction, say, by means of individual. Parents will consider it and will not perceive a problem with lenses in the first weeks of carrying as any accident

You wish to have always accurate, excellent sight, bright, brilliant, healthy eyes, using for this purpose time minimum? You have a desire to provide to the eyes safety, convenience and comfort? Modern one-day contact lenses softly and gently care of freshness, cleanliness, health and unique individuality of your eyes.
One-day lenses are very convenient for users. First of all, that save your time as do not demand any additional leaving. Applying one-day lenses to you it is necessary to carry out only four “procedures”: the plot, has worn, has removed, has thrown out. Conveniently? Undoubtedly. Lenses on the indicators do not concede to traditional lenses of long carrying, and frequently and surpass them. You the new, pure, not polluted lenses, with high factor пропускания always expect some oxygen, a good moisture content. Such lenses simply you do not feel in an eye.

One-day contact lenses

One-day contact lenses

One-day lenses are characterised by high degree of comfort, after all on them protein adjournment do not collect. Thanks to it the risk of development of a syndrome of a dry eye, allergies, irritations is shown to a minimum. At comparison of one-day contact lenses with lenses of planned replacement, advantage always will be on the party one-day as they provide better quality of sight.
At use of lenses of one-day carrying the containers, special solutions for storage of lenses are not necessary to you, it is not necessary to remember date of last disinfection. Frequently the container for storage of lenses can become a source of an infection of an eye. At an ulcer of a cornea disease activators are found out on containers for storage of contact lenses. On occasion solutions for storage can cause allergic reactions or a syndrome of dryness of an eye
One-day contact lenses provide accurate and clear sight, the sharpness of visual perception does not decrease in due course, as it occurs at carrying of traditional lenses of planned replacement. With contact lenses of one-day replacement the risk of occurrence of any problems of an eye decreases, after all patients do not sleep in these lenses.

Many think that one-day contact lenses cost more expensive, than lenses of traditional planned replacement. Whether it is true? After all buying traditional lenses to the person it is necessary to get both the container, and a special solution for storage of such lenses, and энзимные tablets for their periodic disinfecting. Besides, not all people carry lenses every day, for example, some do not put on them during week-end when are at home. As a result cost of one-day lenses for 30 days, approximately equals costs of 30-day contact lenses of long carrying.
The quantity of buyers preferring one-day contact lenses though and slowly, but steadily increases. More and more patients in Europe and in the world trust the health to contact lenses of one-day carrying. Doctors-kontaktologi as anybody another, all advantages of lenses of one-day carrying know, and even more often recommend to the patients one-day lenses.
According to the table, the average index of primary selections of lenses on 15 countries which research was carried out, makes 21 % from total of selections of contact lenses. In Russia while only 6 % of consumers of contact lenses use one-day lenses.

One-day contact lenses are recommended to be used to people, at which:
- Earlier arose папиллярный конъюнктивит;
- Protein adjournment on lenses quickly collect;
- Solutions for care of lenses cause irritation of eyes;
- аллергикам.
Except medical indications it is possible to recommend one-day lenses to following groups of people also:
- To children and teenagers;
- To travellers and people who often go in business trips;
- To sportsmen, public people;
- In general to the users conducting an active way of life.

On a court yard winter, the present winter which we already began to forget, with frosts to – 20С, with snowdrifts of snow and even a blizzard. Trees stand decorated with white fur coats, the frost crackles, crystal icicles – beauty hang down stalactites! But it if to observe of all it from a window of warm apartment or the car. But it is necessary to leave and on street and will fall to this frosty environment, conflicts of the nature to civilisation fruits begin: mobile phones, MPплеера, incorrectly picked up cosmetics not in pleasure and what occurs to such gentle subject as contact lenses are capricious on a frost? Whether they can, at influence of such excited environment, harm and without that to an eye requiring contact correction? After all the question price – sight of the person.

To begin with we will consider anatomy of an eye (eyeball). Apparently from drawing, only small part of an eye contacts to an environment – a cornea. The temperature on a cornea surface makes approximately 35С. Top and a lower eyelid allow to maintain comfortable temperature and environment even in strong frosts. The contact lens also adjoins to a cornea all surface and if to consider that the thickness of a contact lens is estimated in microns it is possible to understand that the temperature on a lens surface makes not less temperatures of a cornea and it irrespective of what contact lenses colour or торические. Besides during blinking it gets warm from two parties, from outside corneas and centuries, and the person often enough blinks. Thus, use of contact lenses at winter, low minus temperatures of air a little than differs from their operation in other, more comfortable season. I will tell it is more, climbers at an ascension to the Everest (where more an excited environment) for protection эпителия corneas (in other words an external layer of a cornea) from льдинок at a snow wind used contact lenses. Simply use recommendations of experts at carrying of contact lenses during the winter period:
Humidify eyes with special eye drops in premises with dry air and central heating batteries; however, it is not necessary to dig in drops directly ahead of an exit on street – to make it beforehand better;
In the street in a frost and a wind it is necessary to protect eyes in lenses also, as well as eyes without lenses – to use warm caps and scarfs;
Carry the modern, correctly picked up contact lenses, strictly соблюдайть recommendations about terms and a mode the carrying received from the doctor-ophthalmologist. In case of occurrence of discomfort, morbidity or it is simple the questions, contact lenses concerning carrying – address to the doctor.
In general, obey doctors of ophthalmologists and carry with pleasure contact lenses at any time year!

When speech comes about correction of sight at children, the majority of parents resolutely draw on points. Unfortunately, it is very frequent children so resolutely refuse to turn in «очкариков». Thus “war” can proceed long enough and even if mums and daddies find a way to force the child to put on points, they cannot be completely assured that small the cunning does not remove them, hardly leaving the house.

By a recognition of ophthalmologists of all world, a lens are the most effective, convenient and simple means of correction of children’s sight. Lenses relieve the child of necessity to wear glasses that eliminates all problems connected with them, and first of all difficulties of psychological character. It is the extremely important for those children at whom very much a poor eyesight, – points with a considerable quantity of dioptries, as a rule, have thick lenses which can be kept only in a bulky frame. Such points just also are at the bottom, on which children hear an insulting nickname «luser». Therefore for them contact lenses – rescue is simple. Besides, one more advantage of lenses is that they practically do not limit a field of vision of the child, do not deform the image of subjects and objects.

Contact lenses are resolved to children since 6 years. According to doctors, at this age the child is already quite capable independently or under partial supervision of parents to look after lenses. However, quite often the ophthalmologist can recommend contact correction and for children is more younger 6 years, however provided that lenses will be looked after by parents.

Contact lenses are the optimum decision for those kiddies who conduct an active way of life – are engaged in different kinds of sports, spend much time in the street, visit various facultative employment and mugs. Physicians recommend to prefer in such cases to soft lenses as rigid it is easy to scratch, split or lose. Soft lenses keep correct position on a cornea surface is better.

myths and the errors connected with contact lenses

myths and the errors connected with contact lenses

MYTH 1. Contact lenses are not comfortable.

You are assured? You sometime tried? You could carry lenses of new generation ACUVUE® ULTRA COMFORT SERIES ™? The first contact lenses have appeared multiyears back, but last years in the field of the materials applied to manufacturing of contact lenses, there was a present revolution. For comparison recollect, what progress will reach in the expired year in sphere of computer technologies. The similar phenomena are observed the last some years in the field of contact lenses.

The material and design of contact lenses allows them to correspond to the individual form of a surface of an eye. Contact lenses regularly replace new, therefore they always remain pure, fresh and comfortable. Contact lenses so are comfortable that users of contact lenses do not feel their presence on an eye.

MYTH 2. I would not like to insert something into an eye.

While you correctly look after lenses, carefully clear, disinfect them and in time replace new, pathogenic microbes do not have chance to survive and get to eyes.

MYTH 4. Contact lenses are harmful to eyes.

Modern lenses make of biocompatible materials, аналогикоторых are widely used in many branches of medicine. Properties of these materials allow lenses to pass oxygen enough to a cornea, therefore an oxygen lack at carrying of modern lenses already in the past.

Remember that contact lenses concern products of medical appointment, therefore they need to use according to instructions of the doctor.

MYTH 5. Contact lenses do not allow eyes to “breathe”.

For health of eyes it is necessary, that the certain quantity of oxygen reached corneas, hence, contact lenses should pass enough oxygen to an eye. The quantity of oxygen varies depending on, whether you use lenses only in the afternoon or do not remove them even for the night. Modern materials of contact lenses possess high gas permeability and provide good access of oxygen to a cornea. Though the material of contact lenses is extremely important for high-grade supply of a cornea by oxygen, but oxygen receipt to an eye depends and on other factors. The ophthalmologist will pick up contact lenses, is better approaching your eyes and providing necessary correction of sight. Important correct care of contact lenses is represented.

The contact lens physically cannot get in an eye-socket. Lenses are напередней surfaces of an eye or, in case of displacement, under centuries. The eye has a natural protective barrier which covers fiber of an eye and surrounds an eyeball подверхним and bottom centuries, interfering with hit of a lens in an eye-socket.

In contact lenses you feel absolutely differently – try!

How correctly to choose contact lenses?

If you have decided to carry contact lenses, first of all it is necessary to visit the ophthalmologist and to ask to pick up to you contact lenses of known mark and high quality. In that, as to mark and quality of lenses, do not make a compromise. Necessarily discuss with the doctor, what lenses will approach your style of life is better and will provide necessary correction of sight. The Doctor-ophthalmologist will tell about available assortment of lenses and will pick up to you trial contact lenses.

Contact lenses have weight of conclusive advantages, but also lacks at them too are. Their main minus is fragility – to damage lenses very much and very easily. At casual handling they can tear, burst, edges can be deformed. Therefore at putting on and removal of lenses it is necessary to be accurate.

Care rules contact lenses

Care rules contact lenses

To wound them follows only in the special container, looking as two small capacities connected among themselves. Each of them is closed by a cover preventing pouring out and evaporation finding in solution. The container always should be pure, therefore it is necessary to wash it regularly with soft soap or a disinfectant solution. The dirty container becomes the fine environment for reproduction of dangerous bacteria, and those, in turn, “eat” into lenses and on their surface “move” in eyes. Besides, ophthalmologists recommend to change the container each 10-12 months.

The second lack consists that lenses “willingly” absorb a dirt. The matter is that almost all modern lenses are made from гидрогелевого a material which has porous structure. On the one hand, its advantages are obvious – гидрогелевые lenses pass air to a surface of eyes, are sated with a moisture that raises comfort of their use. However on the other hand, unfortunately, ability to absorption leads to that in a lens polluting substances and harmful microorganisms easily get. Besides, because of constant contact to the damp environment of a surface of eyeballs on them adjournment of organic character are formed. All it not only spoils a lens, but also raises risk of development of eye diseases and sight deterioration. That it to avoid, it is necessary to care of cleanliness of contact lenses, to look after them, especially if they have a long mode of carrying. It is important to remember that safety of sight depends on it.

To care of contact lenses is admissible to apply only the special means approved by ophthalmologists. The chemical compound of such means is developed taking into account all requirements directed on maintenance of safety for eyes of the person. To use poor-quality solutions dangerously is quite often leads to pitiable consequences, up to blindness. It is not recommended to use means with the expired working life.

Some people ignore recommendations of the ophthalmologist and wash lenses in a self-made solution of salt. As a result service life of lenses is reduced, they spoil, and their carrying causes feeling of discomfort, and in it there is nothing surprising – in house conditions difficultly enough to prepare a solution with the demanded maintenance of salt. If there is no possibility to get expensive means on care of lenses, it is possible to be limited to a usual physical solution which is on sale practically in each drugstore.

During washing of contact lenses it is not necessary to feel sorry for a solution, differently it will not turn out to clear them carefully. Also is inadmissible to reuse one portion cleaning or a disinfectant – already after the first application in it there are microparticles загрязнителей, microorganisms, proteins and so on. Cleaning of lenses should be spent only fingers: on the left palm slightly compressed by “cup” a solution quantity is poured, the lens plunges into it, then a forefinger of the right hand it is accurately rubbed about a palm by soft rotary motions. After mechanical cleaning each lens is necessary for washing out properly a pure solution, to put in corresponding branch of the container and to fill in with a solution.

Without any doubt when you meet the person with unusual or very bright colour of eyes, at once you pay to this attention.

It bewitches besides will. But it is far not to everyone eyes of an emerald shade, as at legendary tsarina Cleopatra, or colour of the spring sky, as at true Irish are given. At the majority of people colour of eyes is defined by a racial accessory: inhabitants of Asia, Middle East and Africa, for example, have is dark-brown eyes, inhabitants of Northern Europe – grey-blue. It is habitual, but, nevertheless, there are many people dissatisfied with natural colour of the eyes. It is a lot of and those who or after a trauma suffers from a birth defect of eyes of cosmetic character: absence of an iris of the eye, pupils of the different size or colour, absence of a crystalline lens, a cataract, an inoperable cataract and so on. It confuses and causes feeling of awkwardness. Whether it is possible to correct it somehow? Certainly, it is possible – by means of colour or оттеночных contact lenses. Them still name decorative.

Colour contact lenses

Colour contact lenses

There are three kinds of colour lenses: cosmetic, оттеночные and decorative. Cosmetic are capable to reverse natural colour of eyes, having transformed even the most dark eyes into the turquoise. Ottenochnye lenses “operate” not so cardinally – they can change only a shade, and only at the eyes having by nature light colour. On brown eyes оттеночные lenses will be simply imperceptible. And here decorative lenses knowingly name «crazy»  – they have so unusual colouring that sometimes even frighten. A little at whom on a back will not run a chill at the sight of red eyes «a-lja count Drakula» or bright yellow with a vertical cat’s pupil! As a rule, such lenses in an ordinary life use seldom, but they perfectly well approach for a cheerful party, friendly draw or shootings at cinema.

Irrespective of a kind of colour lenses, they demand the same leaving and safety measures at carrying, as usual корригирующие. However the special means which are not damaging colouring are necessary for their cleaning. About subtleties of care of lenses of certain mark it is possible to learn in optics salon. In no event it is impossible to clear decorative lenses solutions on the basis of peroxide – from it they become matte.

And the most important: before to get colour lenses, it is necessary to consult with the doctor-kontaktologom and to pass full ophthalmologic inspection. Researches have shown that at frequent carrying decorative lenses can have adverse influence on visual acuity and contrast sensitivity of eyes. At some patients narrowing of a field of vision also was marked.
