"So, Ivan Petrovich, we'll check your zrenitsa. What is this letter, and this "? "Doctor, I can not make out below." "Well, then, it's time to put on glasses, do not worry, at your age, many of them have long been worn." "How - glasses, I'm an opera singer, I'm on the stage, there are all kinds of roles, I can not score glasses." "Well, then try to wear contact lenses. They are invisible, convenient, and vision is corrected no worse than glasses, even better. " On that they decided. But when Ivan Petrovich first picked up a blister with contact lenses, he faced a huge problem in front of him, how quickly and easily learn these contact lenses to take off and dress, and is it painful? And the opera tenor had to turn to his colleague with a beautiful soprano and no less beautiful name Albina Leopoldovna, who had used lenses for a long time and not only to improve her eyesight, but also to change the color of her eyes. Let us join this interesting and very useful science.
Who needs and who should not wear contact lenses?
But before you start to study the question of how easy it is to wear and remove contact lenses, you need to understand the indications and contraindications to the use of this very useful subject. Imagine, conditions and rules of wearing have even decorative contact lenses, and what can we say about lenses that correct visual acuity. So, first of all corrective contact lenses are assigned to people who, according to their professional activities can not wear glasses. For example, athletes, actors, singers, photographers, cameramen and others. In a word, to all those people, for whose activities glasses represent a direct hindrance. Secondly, lenses can be assigned to those who are shy of glasses. After all, the psychology of the patient is also important to consider. For some, glasses are quite an ordinary thing, and for others - a whole tragedy. But there are moments in life when the lens still has to be put aside and saddled with glasses. Here is a list of such situations:
Nystagmus. This is the state of the eyeball, when it constantly fluctuates due to the instability of the eye muscles. Lenses in this case will be only a hindrance. They will rub and traumatize the eye, so that, in the end, the person himself will want to get rid of them.
Inflammatory diseases of the eyes. When the eye suddenly appears a feeling of discomfort, burning and itching, there will be redness or the allocation of sticky mucus, from wearing lenses will have to be temporarily abandoned. These symptoms may indicate conjunctivitis or some other ocular inflammation. By its cure, the lenses can be worn again, but for now you will have to use glasses.
The common cold. During the flu, sore throats or other similar diseases, when the nose and eyes flow, the lens is also temporarily replaced with glasses.
Well, now we turn to practice.
How to properly wear and remove contact lenses?
It is most convenient to carry out this procedure while standing in front of the mirror. And in order not to be confused, which lens, to which eye to put on, take yourself for the rules to start putting on and taking off from the right eye. So, stand in front of the mirror and point the view into the distance, and not at your finger with the lens. With the index finger of the left hand, pull the upper eyelid of the right eye upwards so that the eye remains open, even if you suddenly blink. Place the lens on the cushion of the index finger of the right hand, hold the finger to the eye. With the middle finger of the right hand, take the lower eyelid and carefully place the lens on the sclera. After making sure that the lens has fallen right, remove the fingers. Then look down, close your eyes and turn them under closed eyelids, blink. These manipulations are needed to more accurately position the lens on the eye. Open your eyes and look around. If all the actions were performed correctly, the visual acuity in the eye with the lens will increase. Do the same with another lens for the second eye.
For removal of lenses, the pinch method is used. Stand in front of the mirror, tilt your head forward, and look upwards. With your forefinger, slide the lens down on the sclera, then grab it with your thumb and forefinger, carefully remove it.
And finally
Before you wear the lenses, inspect them and make sure they are fit and in the right position. To understand which side to wear the lenses, put one of them on the cushion of the index finger and look at its shape. The correct position of the lens is similar to a bowl, the edges look up. The inverted lens is like a plate, the edges look outward. If the lenses seem to you spoiled, do not wear them, but rather replace them with others. Take care of your eyes, and good health to you!
