Contact lenses

Contact lenses

Contact lenses, lenses that replace glasses and are applied directly to the eyeball. Made of plastic. Contact lenses are used for cosmetic purposes, for professional (artists, athletes, miners, etc.) and optical (high myopia, one-sided aphakia, etc.) indications. The main disadvantage of contact lenses is eye irritation with prolonged wear. Comfortable to wear and easy to care for, contact lenses have changed the lives of millions of people in need of vision correction for the better.

Contact lenses are not comfortable. The first contact lenses appeared many years ago, but in recent years there has been a revolution in the field of materials used to make contact lenses. The new generation lenses are extremely soft, thin, flexible and, most importantly, stay wet for a long time, providing users with unrivaled comfort. The material and design of contact lenses allows them to match the individual shape of the eye surface. Contact lenses are regularly replaced with new ones so they always stay clean, fresh and comfortable. Contact lenses are so comfortable that contact lens wearers do not feel their presence on the eye.

I don't want to stick something in my eye. This is a normal reaction for those who have never dealt with contact lenses. The phenomenon even has a scientific name - "pakophobia", or the fear of touching the eye. What is unfamiliar at first always inspires doubt, but all fears quickly disappear. Your ophthalmologist will show you how to properly put on and take off your contact lenses, and you will see that it is as easy as putting on and taking off your shoes. Millions of people are quickly mastering the science of contact lens handling, so why not you? Try it and see for yourself.

Contact lenses can lead to eye infections. By themselves, contact lenses do not cause infectious diseases. Inflammation can be caused by pathogenic microbes introduced into the eye from the surface of dirty lenses. Only a lack of hygiene or improper handling of contact lenses can lead to such problems. If you follow your ophthalmologist's lens care instructions and keep in mind to disinfect your lenses regularly, you can enjoy the comfort and benefits of wearing contact lenses without any inconvenience. It's important to remember that the more often you change your lenses, the better it is for your eye health. Replacing lenses frequently with new ones reduces the likelihood of organic deposits forming from fats and proteins in the tear film, which are a breeding ground for microbes. As long as you properly care for your lenses, clean them thoroughly, disinfect them and replace them with new ones in time, pathogenic microbes have no chance of surviving and getting into your eyes.

Contact lenses are harmful to the eyes. Modern lenses are made from biocompatible (do not cause problems on the part of body tissues) materials, analogues of which are widely used in many branches of medicine. The properties of these materials allow lenses to allow enough oxygen to pass to the cornea, so the lack of oxygen in modern lenses is a thing of the past. Contact lenses, correctly selected by an ophthalmologist, if the rules of care, the mode of wearing and the replacement schedule are followed, are a comfortable and healthy means of vision correction for the eyes. Remember that contact lenses are medical devices and should be used as directed by your doctor.

Contact lenses keep your eyes from breathing. Eye health requires that a certain amount of oxygen reach the cornea, therefore, contact lenses must allow enough oxygen to pass to the eye. The amount of oxygen varies depending on whether you only wear your lenses during the day or not even take them off at night. The ophthalmologist will select the contact lenses that best suit your style and provide the necessary vision correction, and, with the advice of your doctor, 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 proper supply of oxygen to the cornea, the supply of oxygen to the eye depends on other factors as well. Proper care of contact lenses is also important. Any deposits on the surface of the lenses are blocking the passage of oxygen, so the lenses must be properly cleaned and disinfected. Proper care and timely replacement of contact lenses will allow you to appreciate all the advantages of modern means of contact vision correction.

Contact lenses can move behind the eyeball. The contact lens cannot physically get inside the orbit. The lenses are located on the front of the eye or, in 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 with sudden movement. Due to the anatomy of the human eye, soft contact lenses are nearly impossible to fall out of the eyes. This enables the contact lens wearer to engage in any kind of sports. The force holding a contact lens against the cornea depends on the lens diameter, so rigid lenses, which are usually smaller in diameter, do not adhere well to the surface of the eye. On the contrary, correctly selected soft contact lenses are extremely rare, this is another reason to visit an ophthalmologist for a professional lens fitting.

Contact lens care is time consuming. Proper lens care is very important to eye health. Fortunately, modern multifunctional solutions have greatly simplified the care and storage of lenses. The length of lens care depends on the wearing mode. The best way to disinfect and clean your lenses is to put them in a special solution overnight that will do all the “work” while you sleep. Be sure to follow the instructions on the multifunction solution insert. If you prefer to keep the hassle of care to a minimum, we recommend choosing daily replacement contact lenses. Every morning you will put on a fresh new pair of lenses, and in the evening you will throw away the used lenses without worrying about cleaning them.

Contact lens wearers should not use makeup. Can. The only thing to remember is to follow the correct procedure: apply makeup after putting on contact lenses and remove contact lenses before washing off makeup. When using aerosols (hair spray, etc.), do not forget to close your eyes so that the smallest particles of the spray do not get onto the surface of the lenses.

Colored contact lenses are worn only by those with vision problems. Colored contact lenses are available with or without a certain optical power for vision correction. Therefore, people with excellent eyesight can use colored contact lenses. But even if you do not need vision correction, you should definitely pick up colored contact lenses from a specialist doctor. Remember that like any contact lenses, colored lenses require proper care.

All contact lenses are the same. Not true. Advances in technology in the field of contact lenses allow us to offer users a wide range of products with different properties. Among the variety of existing contact lenses, two main categories can be distinguished: daytime wear lenses and long-term wear lenses (without removal at night). There are individual characteristics of the eyes, different needs for vision correction, lifestyle also differ from person to person, therefore it is necessary to consult a specialist doctor and choose the best lenses for a particular patient.

The higher the water content of the contact lens material, the more oxygen is supplied to the eye. A very common misconception. New generation contact lenses made from silicone hydrogel materials allow significantly more oxygen to reach the cornea, although their water content is lower than most traditional soft hydrogel lenses.

Contact lenses cannot provide good enough vision - like glasses. We often see the exact opposite situation. Being located directly on the cornea, contact lenses correct vision directly on the surface of the eyes, and not at a distance of 10-12 mm, like glass of glasses, therefore in many cases the quality of vision in contact lenses is much better and there are no optical aberrations (reduction of objects, etc.) ... Unlike glasses, lenses provide a wide field of vision and peripheral vision regardless of the direction of sight, because contact lenses move with the eyeball. In addition, contact lenses do not fog up, do not fall from the nose, do not break, and do not flood them with rain. In any sport, contact lenses are much more comfortable than glasses.

Glasses and contact lenses are addictive. In fact, myopia, hyperopia and astigmatism are the result of the special anatomical shape of the eye and must be corrected. If you are very confused by all these devices for improving vision, you can do a laser operation and look at the world with your own eyes. But still, scientists admit that one parental advice is correct: carrots, as well as other yellow, orange and red vegetables and fruits, which are antioxidants and contain beta-carotene, are really very beneficial for eyesight.

I cannot wear contact lenses because I have astigmatism. In the past, contact lenses for astigmatism were made from a limited number of materials, but innovations in recent years have made a difference. Astigmatism is no longer an obstacle to wearing contact lenses, as toric contact lenses exist.

I have presbyopia and do not need contact lenses, I only use reading glasses or when working at a computer. There are various methods of contact correction of presbyopia (when the need for glasses for working close), for example, the so-called "monovision" correction, when contact lenses with different optical powers are fitted to the right and left eyes. Correction "monovision" gives good results in initial presbyopia (average at age 45). Also, special bifocal lenses are used, which have special zones for far and near distances, which provide users with clear vision in different lighting conditions. Thus, presbyopia is not a barrier to contact lens wear.

I am still too young to wear contact lenses. There are no age restrictions: both children and adults can use contact lenses. Recent studies have shown that, on average, teens start wearing contact lenses at the age of 13. Contact lenses are an extremely convenient way to correct vision for teenagers who go in for various sports and spend a lot of time on active recreation.

I'm too old to start wearing contact lenses. People of all ages can enjoy the benefits that contact lenses provide. The only limitation may be contraindications to wearing lenses, often not related to age or type of contact lenses.

Contact lenses are worth a fortune. In reality, the cost of contact lenses is much lower than people think. With the development of the latest technology, users can choose from a wide variety of contact lenses on the market and, depending on the type of lens and the frequency of replacement. A healthcare professional can help you find the best lenses for your lifestyle, for the correct vision, and for your budget.
