Proper eye lens care
Contact lenses have long ceased to be a luxury for most residents of Russia. In our time, you can buy them even in a conventional machine. To do this, you need to select the necessary dioptries in the menu, throw the right amount - and voila! The goods fall simply into the hands, like a normal chocolate bar or a bottle of soda. But do you know how to properly carry and store an optical device? After all, competent care of the lenses for the eyes is a guarantee of the absence of ophthalmic problems.
Why is it important to look after lenses?
The eyeball is a fragile and delicate organ. Therefore, care for night lenses, their fluorescent analogs, soft and hard varieties is important: it reduces the risk of various inflammations and infections. And this applies to those diseases that can lead to complete blindness. Ophthalmologists say that when wearing an optical device in the corners of the eyes, mucus can be deposited, and on the surface itself - fats and proteins. Their number is very small and inconspicuous from the side. But your eyes sensitively feel them: the visual acuity decreases, wearing of lenses often becomes uncomfortable.
That's why proper lens care will help you avoid the above problems. In addition, in the 21st century it does not require any special efforts: it is worth to go to the nearest pharmacy or a specialized store and buy everything you need. In the range of different tools for cleaning lenses, solutions to help keep them in proper condition. They save human resources: strength, time and money.
All you need to know about
lenses People of any age can wear an optical device. This category includes elderly pensioners. There is an opinion that at the decline of life, the eyes lose their former ability to qualitatively moisturize. Accordingly, the lenses having this function increase the level of comfort during the day. As for adolescents, usually the doctor allows them to use the device from the age of 13.Although everything is very individual. There are many eight-year-olds who are ready to wear lenses. In any case, amateur performance in this matter is not welcome: consultation of the ophthalmologist in each separate case is necessary.
Rules for the care of contact lenses provide for their wearing no more than 5 hours. Although after this time, if there are no negative feelings, use can be extended. Change the lenses every quarter, although there are adaptations of only monthly and even daytime functioning. To wear lenses are recommended not more than 10 years, after which the transition to glasses is necessary and inevitable.
The main disadvantage of lenses and how to deal with it
The optical device significantly increases visual acuity, makes the eyes clear, focused and clear. But, unfortunately, he has some drawbacks. For example, if you ignore the care of long-wearing lenses or other types of lenses, they will become dull and cloudy. The fact is that they are made of hydrogel material, which has a fairly porous structure. Accordingly, the lens, like a sponge, absorbs dust and dirt. Simultaneously, they pass air well to the surface of the visual organ, saturate it with moisture and increase several times the state of human comfort.
Caring for hard lenses, as well as soft or colored, involves the use of only special products approved by professional ophthalmologists. Their chemical and physical composition is not capable of harming the eye, it is aimed solely at the safe use of the device and the preservation of safety for the person. Any solution must be of high quality, and it is very important not to forget to check their shelf life.
How to properly remove and put on lenses?
This procedure is very important. It is the first stage of the process, it is with it that care begins for the lenses for the eyes. Before any manipulation with the optical device, you should thoroughly wash your hands with soap and wipe them dry with a clean towel. At the same time, the tissue structure should be smooth, otherwise small villi will remain on the fingers and can get into the eye or "settle" on the lens. This, in turn, will cause various inflammations of the visual organ. Similar problems are caused by the use of ordinary tap water: it is stiff, and can contain many pathogenic bacteria and microorganisms. Take the rule of washing your hands only with boiled liquid.
Then you can start putting on or removing the lens. In the first case, carefully take it with the tip of your finger and place it on the surface of the visual organ, in the second - remove the same phalanx tip and put it on the palm, greased with a specialized solution. By the way, after removing the lens, it is necessary to wipe it a little: by circular movements of the finger, for 15 seconds. Then the device is turned and repeated manipulation.
On the jar of most special solutions there is an inscription no rub, which translates as "a means that does not require mechanical cleaning".Despite this, the rules of care for lenses provide for not to neglect this procedure. And all because the mechanical cleaning of the optical device, that is, rubbing its surface with the tip of the finger with the help of a solution, gives the maximum effect. Also, professional tools are used to rinse the lenses to wash off all foreign microparticles from their surface. Then they are placed in a special container for storage.
It is important to remember that caring for night lenses or other varieties does not provide for the use of the solution again. The fresh liquid can not be added to the uncleaned container with the remnants of the old product. The lens should be completely immersed in the solution, only after making sure of this, you can tightly close the lid. It is believed that absolute and complete disinfection requires storage of the device in a liquid for at least eight hours. But the specific time depends on the quality of the facility.
Care for colored lenses
The procedure has a number of features. First of all, they concern the means for the care of contact lenses. Store color optical devices better in physiological saline: 0.9% sodium chloride - NaCl. The purification scheme consists of the following steps: 15 minutes the lenses are kept in a solution of hydrogen peroxide( 3%), for the same amount of time they are placed in sodium thiosulfate( 2.5%), then transferred to storage in a container with a special physiological agent.
The scheme, in principle, is traditional. But it differs only by the obligatory use of liquids, which contain hydrogen peroxide. It is an excellent disinfectant, and does not cause allergic reactions. After immersion in such a liquid, the lenses get rid of any microbes on their surface. In addition, peroxide in such formulations lends itself to a reaction - decomposition, after which no active aggressive chemicals remain in the liquid.
Features of storage of different types of lenses
Optical devices are of two types: soft and hard. The first are made of polymer materials, hydrogels and silicone. They are flexible, plastic, letting a sufficient amount of moisture and oxygen to the surface of the eye. Care for soft contact lenses provides all the procedures described above. As for hard lenses, they consist of the same polymers, only more dense. They are used for complex corneal defects: for example, to correct high degrees of astigmatism. Caring for hard lenses also requires all the same solutions. Despite the fact that such devices are more dense, it is necessary to handle them carefully. To damage them is very easy due to their increased fragility and tendency to deformation.
Any varieties of lenses must be stored in a container. In appearance, these are two small round containers, connected by a thin partition. Usually, each has a different color, so as not to mix up where the left and right parts are stored. Each section of the container is closed with a separate lid, thereby preventing the liquid from pouring out or evaporating. Change the capacity once a year.
This should be remembered
Rules for the care of contact lenses are not exhausted by the above recommendations. There are a number of other necessary manipulations that accompany the carrying and storage of this optical device. First, ophthalmologists talk about the need to avoid touching any surfaces of the nozzle tube or bottle with a solution. This can lead to contamination of the lens. Secondly, it is undesirable to get water from the tap on it - this is fraught with infection. Third, keep the containers clean. Regularly change the liquid in them.
Eye care for lenses, especially competent and thorough, is a guarantee that ophthalmic problems will bypass you. If the trouble does arise, please contact the medical institution without delay. The reasons for visiting a doctor may be several: the appearance of dryness in the optic, increased sensitivity to light, the sensation of a foreign body, the appearance of discharge in large numbers, and itching, pain, burning or redness of the eye.
First of all, it is worth mentioning multifunctional solutions for the care of contact lenses. They are used at all stages: washing, disinfection, cleaning and storage. For example, Synergi, Opti-Free Express, Multi Action and others. They do not provide for mechanical cleaning of the surface. Simultaneously, manual removal is more effective, so doctors recommend not neglecting it. In 2009, solution manufacturers received an installation from the Center for Equipment and Radiological Medical Research to include in the annotation to the instruments a recommendation for friction - mechanical cleaning of the lens.
Long-term lens care can include so-called peroxide systems: One Step, Peroxid, Ever Clean and others. For disinfection, a hydrogen peroxide solution( 3%) corresponds to them. In those containers that are sold together with such a tool, a system of peculiar neutralization is built in. When using the solution, it is strictly forbidden to flush the optical device immediately before putting on - this can cause a burn of the shell of the eye. The system is ideal for people who are sensitive to preservatives in multifunctional products.
Daily cleaning methods
Eye care without glasses is not possible without them. In this lineup there are such tools as Multison, Renu Multi Plus and so on. Usually, these solutions are used for cleaning. During washing and disinfection, other liquids may be used. Purify the surface of the lens in this way: it drips a small amount of solution and rubs the surface with a finger for about twenty seconds. Very good and the means for removing protein deposits, especially the Avizor Enzyme and Sauflon tablets stand out - they dissolve easily in a multifunctional solution.
Daily manipulations provide for not only care of the lenses, but also for the eye itself. After all, prolonged wearing of the optical device often causes a feeling of dryness in the visual organ. Therefore, ophthalmologists advise people to use moisturizing drops every day: Comfort Drops, Systane Balance, Sensitive Eyes and others. Not bad "work" and drops, which include hyaluronic acid. They bind and retain moisture, while effectively affecting the surface of the cornea. Such drops include Oxyal and "Hilo-Chest".
Other necessary tools
These are saline solutions "Likotin Universal" or "Lycotin Comfort".They are used for storage and washing, as well as for processing the optical device with high temperature or ultraviolet radiation. Sometimes they are used together with effervescent soluble tablets or other means to disinfect and clean the lens. Use only saline solutions in daily care can not. Proper care for lenses can be performed with the help of cleaning devices - they carry out disinfection with ultrasonic waves. First, the lens is treated with a multifunctional solution and then placed in this apparatus.
Speaking about the means for the care of lenses, it is worth mentioning about enzymatic cleaners. These are the same tablets that help remove excess protein deposits, dirt, dust and mucus from the surface of the optical device. Effervescent agents dissolve easily in any cleaner, mix with it until a homogeneous structure. In them, the lenses are dipped for 15 minutes, after which disinfectants are used.
