Contact lenses

Contact lenses,

lenses, replacing glasses and superimposed directly on the eyeball. Manufactured from plastic. Apply contact lenses for cosmetic purposes, for professional (artists, athletes, miners, etc.) and optical (high myopia, unilateral aphakia, etc.) indications. The main drawback of contact lenses is eye irritation during prolonged use. Modern contact lenses are a worthy alternative to the traditional means of correction. Comfortable to wear and easy to care for, contact lenses have made a difference in the lives of millions of people who need a vision correction.

Contact lenses are not comfortable.

The first contact lenses appeared many years ago, but in recent years a real revolution has taken place in the field of materials used to make contact lenses. Lenses of the new generation are extremely soft, thin, flexible and, what is especially important, long remain damp, providing users with unsurpassed comfort. The material and design of the contact lenses allows them to match the individual shape of the eye surface. Contact lenses are regularly replaced with new ones, so they always remain clean, fresh and comfortable. Contact lenses are so comfortable that users of contact lenses do not feel their presence on the eye.

I do not want to put something in the eye.

This is a normal reaction for those who have never dealt with contact lenses. The phenomenon even has a scientific name – “pokafobiya”, or fear of touching the eye. What is unfamiliar at first always inspires doubts, but all fears quickly disappear. An ophthalmologist will show you how to properly wear and remove contact lenses, and you will see that this is not more difficult than putting on and taking off your shoes. Millions of people quickly master the science of contact lenses, so why not you? Try it and see for yourself.

Contact lenses lead to infection of the eyes.

Contact lenses do not cause infectious diseases by themselves. Inflammation can cause pathogenic microbes entered in the eye from the surface of dirty lenses. Only a lack of hygiene or improper handling of contact lenses can lead to similar problems. If you follow the instructions of an ophthalmologist for the care of lenses and do not forget about the regular disinfection of lenses, you can enjoy the comfort and benefits of wearing contact lenses without any inconvenience. It is important to remember: the more often you change lenses, the better it is for eye health. Frequent replacement of lenses with new ones reduces the likelihood of the formation of organic deposits from fats and proteins contained in the lacrimal film, which are the nutrient medium for microbes. While you are properly taking care of the lenses, carefully cleanse, disinfect them and replace them with new ones in time, the pathogens have no chance to survive and get into the eyes.

Contact lenses are harmful to the eyes.

Modern lenses are made of biocompatible materials (which do not cause problems on the part of body tissues), analogues of which are widely used in many branches of medicine. The properties of these materials allow the lens to pass a sufficient amount of oxygen to the cornea, so the lack of oxygen when wearing modern lenses is already in the past. Contact lenses, properly selected by an ophthalmologist, in case of compliance with the rules of care, wearing regimen and replacement schedule, are a comfortable and healthy eye correction tool. Remember that contact lenses are for medical devices, so they should be used according to the doctor’s instructions.

Contact lenses do not allow the eyes to “breathe”.

For eye health, it is necessary that a certain amount of oxygen reaches the cornea, therefore, contact lenses must allow sufficient oxygen to be passed to the eye. The amount of oxygen varies depending on whether you use lenses only during the day or do not take them off even at night.The ophthalmologist will pick up the contact lenses that best suit your style and provide the necessary vision correction, and if you follow the doctor’s recommendations, you can be sure that your eyes will not suffer from lack of oxygen. Although the material of contact lenses is extremely important for the full supply of corneal oxygen, but the flow of oxygen to the eye depends on other factors. Proper care of contact lenses is important. Any deposits on the surface of the lens block the passage of oxygen, so you need to properly clean and disinfect the lens. Proper care and timely replacement of contact lenses will allow you to evaluate all the advantages of modern means of contact correction of vision.

Contact lenses can move behind the eyeball.

The contact lens can not physically enter the orbit. The lenses are on the front surface of the eye or, in the case of displacement, under the eyelids. The eye has a natural protective barrier that covers the white of the eye and surrounds the eyeball under the upper and lower eyelids, preventing the lens from entering the orbit.

The lens may fall out due to sudden movement.

Thanks to the anatomy of the human eye, soft contact lenses are almost impossible to fall out of the eyes. This allows the user of contact lenses to engage in any kind of sport. The force holding the contact lens on the cornea depends on the diameter of the lens, so hard lenses, whose diameter is usually smaller, do not hold well on the surface of the eye. On the contrary, properly selected soft contact lenses fall out extremely rarely, this is another reason to visit an ophthalmologist for professional lens selection.

Caring for contact lenses takes a long time.

Proper care of the lenses is very important for eye health. Fortunately, modern multifunctional solutions have greatly simplified the care and storage of lenses. The duration of care for the lens depends on the mode of wearing. The best way to disinfect and clean the lenses is to put them on the night in a special solution that will do all the “work” while you are sleeping. Be sure to follow the instructions on the loose leaf to the multifunctional solution. If you prefer to reduce care to a minimum, we recommend choosing daily contact replacement lenses. Every morning you will wear a new clean pair of lenses, and in the evening throw away used lenses, not caring about their cleansing.

Users of contact lenses can not use makeup.

You can. The only thing you need to remember about is observing the correct procedure: apply makeup after putting on contact lenses and remove contact lenses before washing off makeup. Applying aerosols (hairspray, etc.), do not forget to close your eyes, so that the smallest particles of the spray do not hit the surface of the lens.

Colored contact lenses are worn by those with vision problems.

Color contact lenses are available both with a certain optical power for vision correction, and without. Therefore, people with excellent vision can use colored contact lenses. But even if you do not need a vision correction, color contact lenses must be picked up by a specialist doctor. Remember that, like any contact lenses, colored lenses require proper care.

All contact lenses are the same.

It’s not true. The development of technologies in the field of contact lenses makes it possible to offer users a wide range of products with different properties. Among the variety of existing contact lenses, two main categories can be distinguished: day-wear lenses and long-wearing lenses (without removal for the night). There are individual features of the eyes, different needs for vision correction, lifestyle are also different for different people, so it is necessary to consult a specialist doctor and choose the lenses that best suit the specific patient.

The higher the water content in the contact lens material, the more oxygen comes to the eye.

A very common misconception. Contact lenses of the new generation of silicone hydrogel materials allow much more oxygen to the cornea, although their water content is lower than that of most traditional soft hydrogel lenses.

Contact lenses can not provide enough good vision – like glasses.

We often observe the opposite situation. Being directly on the cornea, contact lenses correlate the vision directly on the surface of the eyes, and not at a distance of 10-12 mm, like glasses glasses, so in many cases, the quality of vision in contact lenses is much better and there are no optical aberrations (reduction of objects, etc.) . Unlike eyeglasses, the lenses provide a wide view and peripheral vision, regardless of the viewing direction, because the contact lenses move with the eyeball. In addition, contact lenses do not fog, do not fall from the nose, do not break, they do not pour rain. In any kind of sport contact lenses are much more convenient than glasses.

Glasses and contact lenses are addictive.

In fact, myopia, hyperopia and astigmatism are a consequence of the special anatomical shape of the eye and necessarily require correction. If, however, all of these devices for improving vision greatly embarrass you, you can do a laser operation and look at the world with your own eyes. But still, scientists recognize the loyalty of one parent board: carrots, as well as other yellow, orange and red vegetables and fruits, which are antioxidants and contain beta-carotene, are really very useful for sight.

I can not wear contact lenses because I have astigmatism.

In the past contact lenses for astigmatism were made from a limited number of materials, but the innovations of recent years have made it possible to change the situation. Astigmatism is no longer an obstacle to wearing contact lenses, as there are toric contact lenses.

I have presbyopia, and contact lenses do not need anything to me, I use glasses only for reading or working on a computer.

There are various ways of contact correction of presbyopia (when there is a need for glasses to work near), for example, the so-called “monovision” correction, when contact lenses with different optical powers are selected for the right and left eyes. Correction “monovision” gives good results with initial presbyopia (on average at the age of 45 years). Also, special bifocal lenses are used that have special areas for long and short distances, which provide users with clear vision in conditions of varying illumination. Thus, presbyopia is not an obstacle to wearing contact lenses.

I’m still small to wear contact lenses.

There are no age restrictions here: contact lenses can be used by both children and adults. Recent studies have shown that, on average, adolescents begin to wear contact lenses from the age of 13. Contact lenses are an extremely convenient way to correct vision for teenagers involved in various sports and spending a lot of time on active rest.

I’m too old to start using contact lenses.

People of all ages can benefit from the benefits of contact lenses. The only restriction may be contraindications to wearing lenses, often not related to the age or type of contact lenses.

Contact lenses cost a fortune.

In reality, the cost of contact lenses is much lower than people used to think. Thanks to the development of the latest technologies, users can choose from a wide range of contact lenses on the market and, depending on the type of lenses and frequency of replacement. A specialist doctor will help you choose the lenses best suited to your lifestyle, providing the necessary vision correction and appropriate to your budget.
