It often happens that people with poor eyesight refuse to wear glasses. The reasons can be very different: from discomfort to dissatisfaction with your appearance in them. How alternative option, there are contact lenses for the eyes. There are many varieties of them. Lenses are used for both myopia (or farsightedness) and astigmatism. In addition, this is a good option for children, which will help avoid the development of complexes. However, it is important to know that best lenses for eyes, reviews of which from doctors and friends will be impeccable, may not be suitable for you. Therefore, the first thing you need to make an informed choice is consultation with a specialist.

Types of contact lenses

Based on the type of hardness, there are hard and soft lenses. The first stood at the origins of this type of vision correction, but today they have almost been replaced by soft ones.

Despite this, it is with their help that astigmatism is corrected. Hard lenses for the eyes have more long term services. In addition, they are not affected environment. But in terms of comfort, they are undoubtedly inferior to soft ones. Contact lenses are also divided according to the frequency of replacement. The pair can be changed from once a month to once a year. Of course, it is more correct with medical point vision, rely on short periods of wearing (up to three months). Such eye lenses receive mostly positive reviews from experts; no health problems arise when wearing them. For various diseases use the following types corrective lenses:

• spherical (myopia, farsightedness);
• toric (astigmatism);
• bifocal (presbyopia).

Lenses or glasses?

Main advantages contact lenses- excellent and no distortion of objects. No matter how good the glasses are, they do not allow you to see what is on the sides. To do this, you have to turn around, which is not entirely comfortable. In addition, glasses change the shape of our eyes and their appearance. Their owners feel particular discomfort during the cold season. After all, in winter, glasses often fog up; For these and many other reasons lately Correction with soft contact lenses is becoming increasingly popular among drivers. They are comfortable, hygienic, do not interfere with movement and do not limit the visual field. For drivers correct correction vision is directly related to safety. Modern soft HD provide high clarity of vision, absence of glare and halos, especially in the dark, as well as excellent access of oxygen to the cornea of ​​the eye.

Flaws

Of course, like every medical product, contact lenses have their drawbacks. First of all, when wearing them you need to be quite careful and strictly follow all the rules of use. Compared to glasses, lenses have short term operation and require regular replacement. In addition, these are additional costs. If you wear the product without taking it off for a long time(or not change it in time), it is almost impossible to avoid the occurrence of eye inflammation and conjunctivitis.

Do contact lenses have contraindications?

The specialist will not prescribe lenses for the following factors:

• inflammatory processes that are in the active stage;
• decreased tear production;
• subluxation of the lens;
• glaucoma;
• strabismus (angle more than 15°);
• asthma, respiratory diseases, rhinitis.

Difficulties may arise if a person has a tendency to allergic reactions. may appear when working in areas where large amounts of chemicals or dust are concentrated.

Colored contact lenses

Today, colored eye lenses are in great demand. Reviews about them are positive mainly due to the aesthetic effect. After all, approximately every third woman dreams of a different eye color. The dye used in their manufacture is completely safe. Colored eye lenses do not cause inflammatory or allergic reactions(exception - individual intolerance), they are non-toxic. Besides cosmetic effect, such products can also correct medical deficiencies. They are indispensable for corneal clouding. There are diseases that are accompanied by intolerance sun rays. In this case, lenses will also come in handy. After injury or surgical intervention iris defects often occur. Colored eye lenses will help correct this deficiency.

Types of colored lenses

All pigmented lenses are divided into two groups. The first includes tint products. They have a small proportion of coloring matter and are almost transparent. It is completely impossible with their help, but adjusting the shade is quite possible. They are not suitable for dark eyes at all. The second group is colored eye lenses, which have an opaque coating. These are the ones that are used for a radical change in tone. There are both corrective colored lenses and products without diopters.

Disadvantages of pigmented lenses

One of the main problems when wearing colored lenses is deterioration in the quality of vision in dark rooms. After all, when the pupil dilates, part of it can be blocked by the lens (since the transparent area does not change in size). Naturally, this can significantly worsen the perception of the surrounding space. Colored lenses are comparatively thicker, so their wearing time is reduced to several hours. Otherwise inflammatory processes can't be avoided. Another unpleasant situation that can arise with such products is that they can move when blinking. This should be taken into account when choosing such lenses for the eyes. Reviews indicate that wearing them is undesirable when driving.

Orthokeratology lenses

A new word in vision correction - night lenses. They have a number of advantages. Orthokeratology (night correction) allows you to correct the shape of the cornea with regular use of special lenses. This will make it possible to have during the day. Night lenses for the eyes make the middle of the cornea flatter. This form can last for 1-2 days. This correction method can stop progressive myopia in adolescents. This is wonderful alternative way for those for whom soft lenses are contraindicated, as well as for athletes and people who drive active image life. Orthokeratology is also suitable for those who have constant contact with aggressive components. If the patient plans to resort to laser correction vision and wants to simulate the result, then night lenses will help him with this. However, do not forget that the effect is reversible, and in a day your vision will return to what it was before. Only regular use can give the desired result every day. These eye lenses receive good reviews: they get used to them in about a week, nothing interferes with sleep, and care is quite simple.

How to choose the right contact lenses

The most important rule when choosing vision correction methods is consultation with an experienced specialist. He will check your vision and select exactly the lenses that will suit your eye shape. Having chosen a model, the doctor tries it on. You may need more than one pair of products to avoid discomfort when wearing. Then you will need to wait 10 minutes. After this time, the specialist will re-examine the eyes and the position of the lenses on them. If they are selected correctly, then directly in the optical salon the patient will have to learn how to put on and take off the products himself. The ophthalmologist will tell you how to properly care for your lenses, how often to change them, and what to avoid. According to the recommendations, the duration of wearing should be increased gradually. On the first day it will be enough to wear contact lenses for 2 hours, on the second - 4, gradually increasing to 10-12 hours. There are also special lenses For sensitive eyes. They are made of biocompatible material and have good oxygen permeability. In addition, such lenses are extremely thin, which makes them invisible to the eyes. If there is a feature such as increased sensitivity, then today modern ophthalmology offers many options for vision correction. By the way, daily lenses also recommended for sensitive eyes.

Myths about harmfulness

The question of whether lenses are harmful to the eyes worries many patients. However, when wearing it correctly and regular replacement, the health risk is minimal. Following the doctor's recommendations, you can remember about their existence only when the time comes to remove them. To eliminate the possibility of eye problems, do not forget about hygiene. When putting on or removing lenses, hands should be washed thoroughly with soap. It is advisable to use a waffle towel to avoid small fluff from sticking. It is better to avoid cream soap so that moisturizing oils do not remain on your hands. A portion of disinfectant is intended for one time only. The product container must be kept perfectly clean; it cannot be washed with running water. And you should forever forget about the habit of rubbing your eyes with your hands. In addition to the possibility of infection, there is a risk of damaging the lens. If a woman has to do makeup, then the lenses must be put on before the procedure begins. And only after removing them can you begin to cleanse your face. Regular replacement of contact lenses (as well as containers), scheduled checks vision will help maintain eye health for a long time.

Lenses cannot completely replace glasses. Experts recommend wearing contact lenses and glasses alternately. You can wear glasses at home, and wear lenses to the gym for sports.

The most important point in wearing lenses is the correct selection. Therefore, before purchasing, you must mandatory undergo a vision test to better select the most suitable contact lenses. Since incorrectly selected lenses, as well as glasses, can greatly harm the health of the visual organs.

Experts recommend during sleep to avoid the development of eye diseases. If contact lenses are intended for long-term wearing both during the day and ophthalmologists recommend giving your eyes rest and removing your lenses at night once a week.

Experts strongly discourage drivers from wearing contact lenses because they worsen lateral vision. In addition, during blinking, a short-term blurring of the visible light is possible, which can negatively affect the reaction in the event of an extreme traffic situation.

From all of the above, we can conclude that with proper care and systematic replacement, contact lenses do not. But it is necessary to periodically visit an ophthalmologist so that he can check your vision and, if necessary, adjust the parameters of the lenses.

Consequences of failure to properly care for lenses

When purchasing lenses, a specialist must instruct the buyer about proper care and possible negative consequences in case of non-compliance.

It is imperative to use only the solution recommended for this type of lenses for their storage and storage. Also, during initial wearing, it is necessary to react sensitively to any manifestations of any discomfort and report this to the ophthalmologist. It is possible that a person cannot tolerate a particular type of lens or lens solution.

It is recommended to periodically replace long-term contact lenses with regular ones. This must be done to prevent the occurrence infectious diseases, which may arise due to a constant decrease in oxygen access to.

Contact lenses must be replaced strictly within the specified period; you should not skimp on your health, as they can be very sad.

The risk of eye damage associated with wearing lenses is minimal. But this is provided that you follow your doctor's recommendations. Only a specialist can choose suitable look lenses and give advice on necessary care.

However, all lenses reduce the amount of oxygen reaching the cornea of ​​the eye, thereby increasing the risk of some vision problems. Additionally, wearing them can damage your eyes if you wear them longer than the manufacturer's instructions, or do not disinfect them or replace them as directed by your eye doctor.

Such possible complications When wearing contact lenses, both microbial and acanthamoeba keratitis can lead to vision loss.

There are many myths about contact lenses that may be preventing you from making the decision to start using them. We will try to dispel the most common of these myths so that you can experience the complete freedom that comes with wearing contact lenses.

Myth 1: Lenses gradually worsen vision.

In fact, a person's vision deteriorates regardless of whether he wears lenses or not. Why did this myth arise? It's very simple: a person who wears lenses sees the world completely differently. And having removed the lenses and returning to the previous “image”, he realizes with horror that he began to see worse, and worse than before! In fact, the eyes quickly get used to a clear picture, and the contrast causes imaginary “blindness.”

In a study of children aged 8 to 11 years, there were no significant differences in the development of myopia between those who wear glasses and those who wear contacts ( Jeffrey J Walline et al., 2011).

Myth 2: Contact lenses cause eye irritation.

In the manufacture of modern lenses, biocompatible materials are used that do not cause irritation to the tissues of the eyeball and support natural environment for the eyes. If you use correctly selected lenses, this method of vision correction will be absolutely harmless.

The material from which most modern lenses are made allows a sufficient amount of air to pass freely, so wearing lenses is not harmful. In order for your eyes to “breathe” normally, it is important to take them off at night, as well as to clean them thoroughly and replace them regularly.

Due to the fact that contact lenses fit tightly to the entire cornea and move with the eye, when wearing them, natural focusing is maintained and vision does not deteriorate in any way. It could be in a good way stop its further decline, and also maintain the severity at an adjustable level.

If you properly care for your lenses, the risk of any infections and eye health problems is reduced to zero. It is important to always wash your hands thoroughly before direct contact with lenses, and also follow the instructions of your eye doctor. proper care and wearing.

Thus, the question “Are lenses harmful to the eyes?” the answer can be given - with proper selection, wearing, care, as well as timely visits to an ophthalmologist, the use of contact lenses is not harmful to eye health.

Myth 3: lenses cure myopia

A person thinks: I’ll put on the lenses, wear them for a while, and then take them off and see perfectly! In fact, healing effect Lenses can only be given to children. If a person is over 18 years old, then only surgery can correct nearsightedness or farsightedness. No “miraculous” lenses or glasses are capable of this - you can’t fool nature here.

Myth 4: wearing lenses is a difficult and painful process

In fact, good lenses are not felt, you simply forget that they are on your eyes. They are very comfortable to wear. Many people say that wearing modern contact lenses does not cause any discomfort; they do not feel as if they were not there.

And putting on and taking off lenses is as easy as shelling pears; even a child can do it. When selecting contact lenses, the ophthalmologist explains to the patient in detail how to put them on and take them off, how to care for them, what solution to use, etc. Moreover, in the presence of a doctor, the patient will try to put on and take off the lenses several times. Even children can use contact lenses without harming their vision.

Myth 5: Lenses are no different from glasses.

Only a person who had never heard could say this offensive word The bespectacled man, spoken after, did not break his glasses when falling or in a child's fight, and did not cry bitterly after an unsuccessful date, blaming the boring glasses for his own unattractiveness.

The lenses are free of all these disadvantages. With their help, you can not only show the beauty of your eyes, but also give your look greater expressiveness using colored analogues of this corrective product. In addition, lenses, unlike glasses, have a more complete field of view and high accuracy of peripheral image display. Yes, and protection from ultraviolet rays in lenses, as a rule, it is much more powerful.

Myth 6: lenses are very expensive

The price of a lens depends on many factors, the first of which is quality. So, even the best lenses can be bought ordinary person. If we take lenses by time of use, then the most expensive ones are daily ones. A set of thirty pieces (that is, for a month) will cost you about a thousand rubles. Those who value this can buy lenses from us for a month or six months. They will generally be cheaper than other glasses. You will also need a solution to store lenses, but it is used up quite slowly.

Myth 7: the dye in colored lenses is toxic to the eyes and to the body as a whole.

Tinted and colored lenses use an absolutely harmless dye that has been tested dozens of times.
The dye is located in the central layer of the lens and does not come into contact with the eye. So you don't even have to worry about it. To be even more sure that the lenses will not cause you harm, purchase products from reputable manufacturers and only in trusted stores.

There is no reason to be afraid of lenses, and to ask the question: “Are contact lenses harmful?” They are simple and convenient. With the help of lenses, we can correct vision for myopia, farsightedness and even astigmatism.

All the most common myths about contact lenses have been dispelled. Proper selection of lenses, compliance with hygiene and storage rules will allow you to safely use lenses in the fight against myopia.

Microtraumas when wearing contact lenses

When wearing contact lenses, the cornea experiences stress every day, microtraumas appear on its surface, accompanied by pain symptoms, the sensation of a foreign body in the eye, lacrimation and redness of the conjunctiva. To restore the tissues of the ocular surface after injuries, as an auxiliary therapy, products with dexpanthenol, a substance characterized by a regenerative effect on tissue, can be used, in particular, the eye gel Korneregel. It has a healing effect due to the maximum concentration of dexpanthenol 5%*, and the carbomer included in its composition, due to its viscous texture, prolongs the contact of dexpanthenol with the ocular surface. Korneregel remains on the eye for a long time due to its gel-like form, is easy to apply, penetrates into the deep layers of the cornea and stimulates the regeneration process of the epithelium of the superficial tissues of the eye, promotes the healing of microtraumas and eliminates the sensation of pain. The drug is applied in the evening, when the lenses are already removed.

Avoid exposure to any harmful or irritating fumes or fumes while wearing lenses.

*5% is the maximum concentration of dexpanthenol among eye shapes in the Russian Federation. According to State Register medicines, State medical products and organizations ( individual entrepreneurs), engaged in the production and manufacture of medical devices, as well as according to data from open sources of manufacturers (official websites, publications), April 2017
There are contraindications. You need to read the instructions or consult a specialist.

Cosmetic

Cosmetic lenses can completely change your natural eye color. Such models are especially suitable for dark-eyed users: the color change occurs due to the opaque color of the lens. Only the central part of the contact lens, located in the pupil area, remains unpainted. When painting such lenses, a multilayer patterning technology is usually used.

The color layer is located inside the lens material and does not come into contact with the eye.

Tinted

At misuse any lenses can be applied serious harm eyes. Soft lenses harm the eyes if worn incorrectly and if instructions for use are not followed. In this case, they can deteriorate the quality of vision and lead to inflammatory diseases eye.

Specifics of wearing mode

How to put on lenses

Colored and tint lenses do not change the image of the world in any way. After all, in the center they are transparent. But a person’s pupil dilates from bright light or when excited and may appear under the colored zone. In this case, the perception of reality will be somewhat distorted. There's nothing wrong with that, however When driving a car, it is better to refuse such an accessory.

Carnival lenses are not intended for long-term wear. Such lenses are thicker, so they transmit oxygen less well. In addition, carnival lenses reduce the clarity, contrast and quality of vision. If we compare carnival and colored lenses, the latter guarantee best quality vision.

• Pay attention to the manufacturer.
• In addition to color, lenses also have a “pattern”. Some of them may look unnatural, so carefully choose a manufacturer whose products will completely suit you. If you don't want to make a mistake with the color of your lenses, then go to online services, where you can “try on” certain options.

Are colored lenses harmful?

This development has been popular for more than 30 years, and over the past time a lot of supporters of the theory of the unsafety of such a product have appeared. In particular, such statements are based on the unsafety of the material from which they are made for the eyeball.

In fact, colored lenses are produced at the most modern technologies, and with the use of soft material used to create conventional contact correction products, which completely prevents any discomfort, pain or the appearance of micro damage to the iris.

Soft CLs are made from hydrogel and silicone hydrogel, hard ones are made from polymer. The coloring pigment is contained between layers of material without penetrating into the eyeball, and the unpainted middle does not interfere visual function and does not distort the overall color perception.

The “transparency” of the center of the lens does not distort the perception of tones and shades of the surrounding world.

But the product can really cause harm if used incorrectly. With frequent or prolonged wearing disturbances, visual acuity may decrease or inflammatory processes may develop. To prevent such complications you need:

1. Follow the rules of eye hygiene and storage of contact lenses.

3. Before initial use, consultation and examination by an ophthalmologist is required.
4. Wear it no longer than the specified time, preventing tension, dryness, and also to maintain oxygen access to the cornea (for hydrogel).

How long can you wear it?

The specifics of the wearing mode depend on the type, material from which the contact lenses are made, the manufacturer, and other nuances. On average, models for changing style or emphasizing the natural iris are worn no longer than 6-8 hours a day, after which they are removed, giving rest to the eyes. It is somewhat more difficult for oxygen to penetrate through the colored fragments, which increases the load on the organs of vision.

Some companies (Akuview and others) are engaged in the production of CLs with a one-day service life and an allowed duration of use of up to 12 hours. After this time, the product is disposed of.

Carnival CLs are distinguished by the specifics of their manufacture, due to a very dense coating of colored pigment, they are thicker than tint and decorative species, and more impede the access of oxygen to the iris. On average, their use is limited to 2-4 hours.

To save healthy vision You must observe the wearing time of cosmetic or corrective ophthalmic products in accordance with the instructions and recommendations of a specialist.

Opinions about the dangers of colored contact lenses are unfounded, because... production and the materials used in its process are no different from conventional means of contact vision correction. The reason for any painful sensations is poor care or storage, as well as prolonged wearing, which violates the recommendations of the ophthalmologist and the instructions for use.
