Before buying contact lenses, many people ask themselves: do they spoil contact lenses vision?

If we talk about lenses for vision correction, then before buying lenses you should definitely visit an ophthalmologist who will select the right lenses for you for the required parameters. A lens correctly selected by a doctor is not capable of spoiling your vision; it forces the muscle of your eye to work, thereby correcting your vision. Some contact lenses are even capable of treating progressive myopia.

It is not recommended to buy contact lenses without a prescription from an ophthalmologist, since a selected lens with the wrong parameters, radius of curvature or diopters may not only not correct vision, but also worsen it, as well as cause infection of the mucous membrane or any other eye injuries. Also, improperly fitted lenses can lead to the development of vision defects such as astigmatism, myopia or hyperopia.

In addition to visiting an ophthalmologist, a very important part is proper care behind contact lenses. This means that you need to comply with the period of wearing contact lenses, and daily clean them with a solution, if these are lenses of planned replacement. The period of wearing contact lenses is always indicated on the packaging, so when putting them on, be sure to check their wearing period and stick to it. Over-wearing contact lenses can also adversely affect your eyes and vision, for example, gradual vascular growth into the cornea of ​​the eye is possible. You can read about the extension of contact lenses here.

First of all, you must take a responsible attitude towards wearing contact lenses, since the development of diseases that can subsequently impair vision can be caused precisely because of improper care of contact lenses and non-observance of the wearing period. If you use decorative cosmetics, you should carefully choose shadows or mascara that will not crumble. Particles from cosmetics caught directly under the lens can lead to the unpleasant sensation of sand in the eye.

Also, with the help of contact lenses, you can change the color of your eyes and appearance... If we talk about colored contact lenses, they need the same careful care as contact lenses for vision correction, since any contact lenses are a medical device. Many people are of the opinion that colored contact lenses can impair vision. However, they will not spoil vision, as well as lenses for vision correction. Colored lens it is painted only near the iris, while it has a transparent zone near the pupil. You do not have to worry about getting the dye into the eye, as the colored contact lens is colored on the inside of the lens and does not come into contact with the cornea.

But it is worth paying attention to the carnival lenses (Crazy), which are almost impervious to oxygen. They are not intended for everyday wear and should not be worn for more than 6 hours, as they can reduce the quality of vision, such as color rendering, clarity or contrast. Carnival lenses, like all contact lenses, require proper care and wear. If not properly maintained, these contact lenses can cause a range of eye problems such as pain, inflammation, and infections. Ophthalmologists warn us about this. If colored and carnival lenses can be worn with good eyesight, this does not mean at all that they do not need to be looked after like contact lenses for vision correction.

Any contact lenses in no way spoil your eyesight, if you have previously visited an ophthalmologist and selected the correct contact lenses together with the doctor. Wearing time and proper care of contact lenses are the main factors that ensure the health of your eyes!

Lenses are designed to radically change the iris. At the same time, they do not stain in the area of ​​the pupil and therefore do not distort the color perception of the owners. However, it must be borne in mind that when the lighting changes, the diameter of the pupil also changes. If the pupil is constricted, a different colored iris may be visible in the clear area of ​​the lens. If it expands, the colored area enters the field and creates a clouded sensation in the eyes.

Colored lenses are best removed while driving in the dark when they impair vision.

In order to bring the appearance of a colored lens as close as possible to the natural one, modern manufacturers use 2 or 3 dyes to create an iris pattern, imitating the border, the main color and other features. The colored layer is contained in the inner part of the lens and does not come into contact with the cornea, so there is no need to worry about getting the coloring matter in the eyes.

Tinted contact lenses are much weaker than colored contact lenses. Their task is to enhance and brighten the natural color of the iris. In this case, the pupil area is also colored, so the color rendition, albeit weakly, is disturbed. On the other hand, in bright light, when the pupil is constricted, the true iris is not visible, and therefore tinted lenses look more natural.

Carnival, or crazy-lenses, are distinguished by bright unusual colors or patterns in the form of a cat's eye, dollar sign, soccer ball, etc. They are designed for special occasions, not everyday wear.

Rules for wearing colored contact lenses

Colored contact lenses are not designed to be worn as they are nearly impervious to oxygen. You can wear them no longer than 8 hours a day and be sure to take them off at night. This is especially true of thick carnival lenses, which fundamentally reduce the quality of vision: color rendering, clarity, contrast.

Lenses should not be used for longer than the manufacturer's instructions, as organic deposits build up over time, causing inflammation and irritation of the eyes. In addition, soft contact lenses easily absorb a variety of impurities from the environment, so it is undesirable to wear them in smoky rooms and in production where aggressive chemicals are used.

The solution in which the lenses are stored must be changed daily. Use only clean hands to insert and remove lenses.

Those who use cosmetics need to choose mascara and shadows so that they do not crumble. Particles of paint trapped under the lenses create a gritty feeling in the eyes.

You cannot choose lenses without consulting a doctor. Incorrectly fitted lenses create discomfort and damage vision.

Nothing is more valuable than seeing the world around you with your own eyes. Enjoy the sunrise and sunset, admire the beauty of the surrounding world. But sometimes it happens that a person loses his sight, and then a problem arises. What to choose, lenses or glasses? There is a lot of controversy around this issue. There are supporters that the use of eye accessories (glasses, lenses) impairs vision. Others believe that if you use colored lenses, then there is no harm.

Do lenses damage your eyesight?

It is not glasses and other accessories that spoil vision, but improper care and choice of them. Also, the professionalism of the doctor plays a huge role, who will be able to explain everything correctly and give recommendations on their use and operation. And answer the questions asked by the patient. What is more beneficial and what is not? The widespread use of lenses allowed a person to regain vision, and not only: to become fashionable and stylish. Colored accessories help us with this. Everyone uses lenses in their own way. Someone to correct their vision, and someone wants to stand out among the gray crowd, and uses carnival lenses. But not everyone knows whether or not they spoil their vision by such actions. That is why it is worth choosing an experienced professional who will preserve your eyes and good vision. Colored lenses can be matched to the color of your eyes, or you can choose the one color range whichever you like best.

But most people are looking for answers to the question, are lenses harmful to vision? In order to get an answer, it is worthwhile to understand that the appointment should be carried out only by the doctor after the examination.

Lenses are colorless and colored. For those who wish to change the color of their eyes, colored ones are naturally used. They emphasize the individuality of the person, allow you to distinguish yourself from others. In order to avoid problems with vision when using them, you need to carefully follow the recommendations that the ophthalmologist has prescribed. After all, if you take the medicine not according to the instructions, there may be complications! So in this case. Colored or colorless lenses can become enemies to your eyes if you choose and wear them incorrectly. This is especially true for women. Why? Because cosmetics that are not compatible with contact lenses can cause inflammation in the mucous membrane of the eye. And if you constantly wear colored ones, and you neglect these rules, then your vision may deteriorate, which will negatively affect your Everyday life... Since contact lenses are very sensitive to varnishes, gels, when choosing them, you should pay attention to the presence of a mark for compatibility with the use of contact correction.

As for the harm to vision when using them, we can say that there is no harm. If you wear them correctly, remove them correctly and take care of them, then they do not bring harm. But even if you decide to wear colored lenses, you should go to an ophthalmologist and consult with him. He will give recommendations and, following them, you should not fear for your eyesight.

Vision can be impaired whether you are wearing glasses or other eye accessories or not. It gets worse due to overuse, injury, improper indoor lighting, and so on.

Wearing lenses allows a person with vision problems to see the clear and colorful colors that surround them. This is a plus in contrast to the use of glasses.

There are people who believe that wearing them contributes to development poor eyesight, fungus and inflammatory processes in the eyes. No, it’s not like that. Of course, if you violate the mode of their operation, then discomfort, discomfort and redness of the eyes are possible. All inflammatory processes that arise are due to microbes that directly hit the lens with improper storage and care. But if an experienced ophthalmologist has appointed you a type, type and wearing rules, then you have nothing to be afraid of.

If you suddenly feel tired while sitting at the computer or while reading a book, writing and other activities that are related to work and eye strain, headache, burning in the eyes, you need to take a break. Changing your lenses daily can help keep your vision healthy.

To choose, you need to know the material of manufacture and choose the most environmentally friendly and safe option from all. Today there are many types to choose from.

Hard - used for correction high degree astigmatism, are prescribed only by the doctor who carries out the treatment. They are quite uncomfortable and less convenient, therefore, in the absence of a specialist's recommendation, it is advisable not to choose them.

Soft - made of hydrogel materials, they can be worn up to 12 hours. Of the advantages, it is worth highlighting their hypoallergenicity.

Silicone hydrogels are like soft lenses: they have many positive qualities, which allows them to be attributed to a separate variety. You can wear this look for a long time. Not recommended for those sensitive to silicone. They require special care.

If you wear lenses every day, be they colored or clear, are they harmful? No. Thanks to the material from which they are made, the use of contact vision correction does not cause rejection foreign body, and their ability to transmit oxygen to the retina is a positive quality. Therefore, they do not spoil the eyesight.

The use of contact lenses made it possible to correct vision without surgery, which allowed the patient not to worry about the consequences.

Rules to remember and follow when using lenses:

* do not wear lenses for more than the specified period;
* it is recommended to take them off before going to bed;
* do not wear lenses indoors where there is a lot of dust and smoke;
* it is worth choosing only after consulting a doctor.

Whether the lens will harm or benefit is up to you. After all, it is you who will take care of them, and you need to follow all the instructions that the ophthalmologist prescribed. Application and use in moderation will not only correct your vision, but also allow you to become extraordinary.

The change of image has become a common thing for a modern person. But you won't surprise anyone with new costumes, hairstyles or jewelry. And you want to look unique. A new eye color that perfectly matches the style of clothing is what is really fashionable today. To transform, it is enough to purchase colored contact lenses. But they have already managed to acquire opponents who believe that colored CRs spoil their eyesight. Let's figure out if this is really so, and what in reality can harm the eyes.

It is difficult to know if colored lenses are harmful to your eyes without understanding what they are. Therefore, first let's talk about their composition and functions.

There are three types of colored contact lenses:

1. Shading;
2. Cosmetic;
3. Decorative.

Tinted lenses are designed to change the tint of the natural iris. They will not change its color, but accentuate it and make it more saturated. Owners dark eyes such CLs will not work, because the dark color interrupts all possible shades. The lens surface appears translucent.

Cosmetic counterparts, on the other hand, completely change color. In the place where the iris should be located, the lenses are colored and opaque. They are suitable for owners of any eye color for decorative purposes or to hide visible defects: a thorn, as well as various colors or the absence of a part of the iris.

Decorative contact lenses are also called carnival. They do not just change the color of the iris, but completely transform eyeballs... With them, you can create any image and imitate the eyes of a cat, shark, vampire and even a zombie: there are no restrictions, even the shape of the pupil changes visually. The purpose of such CLs is a one-time use for attending a party.

Colored CLs are hard and soft. They are made from the same materials as conventional lenses:

• Hydrogel (MCL);
• Silicone with hydrogel (MCL);
• Polymers (ZhKL).

Since colored lenses have the same composition as conventional contact pairs, their gas permeability is quite high. The oxygen transmission percentage can be slightly reduced only due to the presence of a thin pigment layer located inside the lens. But its area corresponds to the area of ​​the iris and does not take up much space. Therefore, it has little effect on the ability to pass air.

Is there any harm to eyesight?

It is believed that colored lenses are dangerous in that they can impair vision. Proponents of this idea are sure that eye contact with the dye is very harmful: "it's chemistry."

In fact, nothing threatens your eyesight, because the pigment layer is located between the transparent hydrogel and polymer layers of the lens. This means that the paint does not come into contact with the mucous membrane of the eyes and cannot harm it.

Are there any contraindications for healthy eyes?

Those who want to change the color of the iris are often interested in whether colored lenses are harmful to healthy eyes (meaning with normal vision)?

Indeed, CL are designed to correct vision. It is also known that improperly selected diopters can spoil it even worse, what can we say about a change in the optical power of healthy eyes. Does this mean that if a person has good eyesight, he cannot wear colored lenses?

It turns out that most tinted lenses do not change the optical power of the eyes, so vision does not deteriorate from them. And if a person has a bad initially, then in addition to changing the color of the iris, in addition, he can bring his vision back to normal. True, today it is still available only to myopic people. This is due to the fact that corrective color CLs are produced only in the minus range of diopters.

Narrowing of the field of view: truth or myth?

You may have heard that the range of vision narrows when wearing colored lenses. There is some truth in this, but only in part. Let's figure it out.

For 100% visibility, light must enter the eyes from all directions. Then the central one will be in order. If on the way to the retina there is an obstacle in the form of an opaque body, then peripheral vision suffers.

The human eye is designed so that the pupil can change size depending on the brightness of the light flux. If the brightness is high, then the pupil narrows, and if it is low, it expands.

Colored lenses are colored only in the place where the iris should be located. In the center, it is transparent. Therefore, light rays enter the eyes unhindered and focus on the retina. But only during the day. In a darkened environment or at dusk, the pupil expands so much that its edges go beyond the color border. In this case, only part of the light penetrates inside, so visibility is reduced.

How does color perception change?

Another popular question: do colored lenses harm color perception? Remember the situation when a person with a color CL has a reduced visibility. This happens when the colored layer overlaps part of the pupil dilated in darkened conditions. And this applies only to cosmetic and decorative lenses, the coloring layer of which is opaque.

Now imagine tinted lenses. If it gets dark, the pupil will dilate. Part of it will be behind the pigment layer, which remains transparent. This means that visibility will not be reduced, but some of the rays will pass through the colored substance. Only under this condition is a violation of color perception possible. In bright daylight, when the pupil is already a transparent colorless circle in the center of the lens, the eyes can see as well as without the lenses.

Chronic conjunctivitis - a consequence of wearing colored CL?

The last thing that is attributed to colored lenses is the development of chronic conjunctivitis. This is the name of chronic inflammation of the conjunctiva - the mucous membrane of the eye. Initially, the disease is always acute. Its causes can be:

• Allergy;
• Viruses;
• Bacteria.

If the inflammation does not go away for a long time, and the conjunctiva continues to be mechanically irritated or harmful microorganisms, then the disease goes into chronic form... But are the lenses to blame?

There is no chronic viral conjunctivitis. If we consider allergies, then as long as a person is in contact with an allergen, conjunctivitis will not go away. And the lenses have nothing to do with it. The bacterial form of the disease is caused by an infection in the eyes. This happens only if dirty hands climb into the eye. And who is to blame if the lenses are changed by a person who does not follow the rules of hygiene?

Chronic conjunctivitis is not caused by wearing contact lenses, but by non-compliance with the hygiene rules associated with their use. These include: changing lenses with dirty hands, wearing them in excess of the norm (longer than the permitted period or leaving them overnight), improper care of the contact pair.

In the same way, you can pick up an infection with ordinary call lines, so their color performance does not add a percentage of risk at all.

So do colored lenses spoil your vision? It is impossible to answer this question unequivocally. If you pick them up incorrectly, purchase from an unscrupulous manufacturer, wear or care incorrectly, then you will certainly feel the harm. But the same is the case with conventional, vision-correcting contact lenses. Therefore, if you want not only to transform, but also to preserve the health of your eyes, contact an ophthalmologist to help you make the right choice. Subsequently, you will have to take care of the CL and observe the mode of wearing them. Then you will not feel the negative effect of colored lenses and can enjoy a new look.

Many people suffering from vision problems have found hope for a fulfilling and comfortable life thanks to the advent of contact lenses. According to thousands of users, lenses allow you to feel more confident, see the world more clearly and lead an active lifestyle.

It is now possible to buy contact lenses without any problems in any optics, so often new users have many questions about the safety and rules of using such a popular tool.

Myth number 1. Lenses spoil vision

The main question, discussed in dozens of pages of Internet forums: how do lenses affect vision? Some users claim that while wearing corrective lenses, their vision has deteriorated slightly and the reason for this is the lenses. In fact, vision deteriorates with significant eye strain and improper lighting, regardless of whether you use contact lenses or not.

The main advantage of the lenses is that they are capable of giving a picture of the surrounding world, excellent in clarity and detail, when worn. When abandoning lenses and switching to glasses, people with vision problems note that they see everything around much worse, not as clearly as before.

The sharp contrast of images can cause a feeling of decreased vision and a feeling of a "blurry world". A visit to an ophthalmologist is able to determine real changes and establish the required diopters for a comfortable life.

Myth number 2. Lenses provoke disease and blindness

Also, stories about the dangers of lenses lead to the myth-making of users about inflammatory processes and fungal infections after wearing contact lenses. The lenses allegedly block the flow of oxygen to the cornea and lead to blindness.

It should be noted that contact lenses - medicine... Their selection should be carried out by an experienced doctor who will select a product with an acceptable oxygen permeability percentage and tell the patient how many hours this type of lens can be worn.

If the permissible time is exceeded, unpleasant consequences are quite possible in the form of reddening of the eyes and disorders of the condition of the conjunctiva. But after all, disregard for the recommendations of doctors when taking any medicines leads to side effects, is not it?

To avoid hazards when wearing lenses, consult an experienced ophthalmologist who will determine the radius of the lenses, type (soft, hard), duration and wearing mode. Contact lenses do not spoil your eyesight if you follow only two rules: use only the means selected by your doctor and adhere to the rules of wearing.
