There is a contact! Lenses or glasses - choose

The most common questions associated with contact lenses, responsible physician ophthalmologist Irina Troshina


Glasses or contact lenses (CL)? The choice in favor of the latter is done by those who know their advantages, can choose suitable to wear by the rules and to take care of them with proper care.





Advantages


More effective vision correction for myopia patients (short-sighted).


- If in the right and left eyes myopia or hyperopia different lens corrects vision. Bespectacled same experiences discomfort, eyes can't handle the load, if the difference between the right and left lenses of more than 2 diopters.


The so - called toric CL cope even with the most difficult astigmatism, before which points to "fold".


- Multifocal CL immeasurably easier and more efficient with farsightedness. One does not have to bother with two pairs of glasses for near work and for continuous wear.


In the lens - unlimited field of view: does not interfere with the frame of the spectacles. This advantage is very much appreciated by drivers.


The eyes behind the lenses look natural: do not decrease as the myopes in glasses with a high degree of myopia, and not increase, as farsighted.


- Help out in any field, when playing sports.


- Do not fog up in the cold, as spectacle lenses.


- No annoying reflections that are so hampered-by-four.


- No danger of injury points, which is important for drivers.


- Lenses replace the missing lens (this happens after injury or cataract extraction).


- Salvation for someone who doesn't want to wear glasses, considering that they do not add to his beauty. So I loved CL teenagers, actors.


- Ability to change the color of the eyes.




Disadvantages




- What would be a nice lens, it's still a foreign body in the eye, which now will need close attention.


- More complex system of care compared with glasses, who simply wipe the glass.


- Relatively high cost. Buying glasses, even in an expensive frame, the person uses them for three years or more. And CL need to be changed regularly. When the lenses of scheduled replacement, will have to spend more on products for disinfecting and processing.


- The need for constant observation of the doctor. Even those who long is CL and learned to deal with them, should at least once in six months seem to the ophthalmologist or the HR lenses, working in the salon optics.





Whom lenses will not work


With acute conjunctivitis, keratitis (violation of the surface layer of the cornea).


- Ptosis - drooping of the century.


- HIV and graves ' disease.


- If a person applies hormonal drugs (including contraceptives). They cause dryness of the cornea.




Select material





Hard and soft. The latter are made from a composition which can absorb water, becoming soft and flexible and allow oxygen - eyes "breathe". Although soft lenses are used in 96% of cases for hard work also remains (keratoconus - conical cornea, at high degrees of astigmatism, in cases when a person has both myopia and hyperopia). For very large diopters also have to access the hard lenses. Soft CL are hydrogel and siliconvalley. Last through the Central part of the lens - miss 5 times more oxygen, which, of course, like the eye. But more moisture in the hydrogel.


Hard lenses are made of plastic, which are much easier to care for, while wearing these lenses will not have the complications that can occur when wearing soft. But, in the General opinion, soft CL more comfortable and, once you taste them, it is difficult to return to the old hard - as gas-permeable and gas-tight.





Determine the mode of wearing



Dayif you are in daily lenses no more than 8-12 hours, your choice - hydrogel lenses. To sleep in these CL impossible in any case.


Flexible:

suitable for those who need up to 7 days to be in the lenses all day. Or even to wear the CL - and only a month to take them off. Leave the lens at night allow only siliconvalley. If you are more than 16 hours will stay in the hydrogel, the eyes in the evening will feel hypoxia (oxygen starvation) will begin to blink frequently.


When the lenses should relax





Happened overgrowth of blood vessels. This happens if for a long time to use hydrogel lenses. This is due to the lack of oxygen, which is experiencing eye. The cornea choroid, and to compensate for hypoxia, the blood vessels grow into the eye, often superficial and shallow. No unpleasant sensations in humans at it. The treatment is to put the patient on breathing siliconvalley lenses. Can some period to opt out of the CL.



In the season of hay fever. Allergies at this time, is to wear glasses.



Struck the flu, the common cold. Remove CL, infection may result in complications in the eye. During illness wear glasses.



The lens is rubbed her eyes. Immediately contact your doctor. Need to relax from the CL as long as the cornea heals, and receive treatment.


Especially love the blue, purple and green lenses young girls. In addition to the tint and color are sparkling lenses, fluorescent and other outrageous new items: "crazy" (specially for Halloween), in the form of a cat's eye, leukoma, a dollar sign. Constantly wear them from morning until late at night is bad. These lenses are tight, don't let in enough oxygen - eye feels discomfort. It is better to alternate them with ordinary lenses and holders of normal vision wear only periodically.




Patients with diabetes can be worn lenses, but only with high oxygen permeability. Such patients should be regularly seem to the oculist: lowered immunity provoke keratitis and conjunctivitis, and reduced sensitivity of the cornea makes it vulnerable (changing the lens, one can unwittingly hurt her).




The most popular today is the frequent lens replacement (after two weeks or a month and a day. One convenient because there is no fuss with care - man throws the old couple in the evening and in the morning puts a new sterile and, therefore, less risk of getting the infection. Daily especially good for teenagers, boys and all those who are not very disciplined and accuracy.




If you wear lenses 2-3 times a week, buy a day.


If the lenses you need every day, but you are afraid of the costs (day more expensive lenses continuous wear), stop your choice on the two-week-month.


If you are going on a business trip or on vacation, buy a day trip CL (you don't have in zitsa with a solution, to haul containers for their care).





Question-answer


The most common questions associated with contact lenses, responsible physician ophthalmologist Irina Troshina.





- Same power of spectacles and contact lenses?
- No, because it takes into account the focal distance from the eye to the lens. If negative soft contact lens wear on the eye - distance decreases, respectively refraction increases, the power can be reduced. And plus CL is the opposite - you have to take more power.





- Will not interfere if lenses for dry eye syndrome?

In a good optician's shop in the examination always the specialist assessment of tear film and tear production, makes the necessary tests. Depending on the results, you can choose CL with a moisturizing component, assign advanced the moistening and lubricating drops. They especially need those who are first time wearing contact lenses. As a rule, drugs, artificial tears are needed and those in KL working at the monitor in the office, where the included air conditioning.


- How cosmetics for the eyes is to use man in the lenses?



- Quality. It is normally hypoallergenic. You can buy a special shadow, mascara and pencil for those who wear CL. Insert the lens into the eye relies before applying cosmetics to her not to make a mess. And in the reverse sequence it is necessary to act, removing makeup: first remove the lens and then to take up remover.
