Advantages and disadvantages of contact lenses
Lenses, unlike glasses, give the opportunity to easily consider the world around - they do not distort the picture and do not limit the angle of view. This means that wherever you do not move eyes, without turning the heads, you can still see objects in the smallest details. The second substantial plus contact lenses is their delicacy. If they are chosen correctly, you will never have a feeling of a foreign body in the eye, which you will not say about glasses who are prayer on the nose. That is, such a significant problem as weak vision, with lenses can be completely forgotten. The lenses do not fade in contrast to the glasses, besides, specialized models are able to protect their eyes from harmful ultraviolet. Modern materials from which contact lenses are created, do not limit the flow of oxygen to the cornea, allowing the eyes «breathe». Lenses are a chopstick for people whose profession does not accept points (actors of the theater and cinema, athletes), and many motorists assure that wearing contact lenses gives them even more self-confidence.
Indications for the use of contact lenses are:
- myopia and farewell;
- keratoconus;
- Aphakia;
- Protection of cornea and ensuring her healing.
However, where there are advantages, be sure to already have cons. First, lenses may not come up - your eyes simply will not be perceived by responding with tears and strong irritation to a foreign object. True, the percentage of such cases is very small. Secondly, with all its universality, the lens is very capricious - it is easy to break it with an awkward movement of fingers. If you forget to forget and lose your eyes, the lens can "crawl" under the eyelid - to get it from there it is difficult, you need to blink often so that it itself has become in place. If the street is windy, a lot of trouble will be delivered by the sorties, flying into the eyes - will be very uncomfortable. Owners of long-haired cats also sometimes have to be disadvantaged - their undercoat, more like fluff seems to be only waiting to settle on the lens. Remove it without removing the lens, almost impossible. Contact lenses are not recommended to wear during a cold - the eyes strongly distinguish the protein secret, which immediately settles on the surface of the lens in the form of an immemorable small white dots, thus leading it in disrepair. In other words, be prepared for the fact that sometimes you have to buy a new couple of lenses, without waiting for the expiration of the shelf life of the one that wears.
In addition, there are contraindications for wearing lenses:
- inflammatory or infectious processes (keratitis, blepharitis, conjunctivitis);
- chronic eye allergy;
- violation of the composition of the tear liquid;
- reduced susceptibility of the cornea;
- xerofthalmia (dryness of the cornea against the background of tears impairment);
- unfinished care and unmotivated use of contact lenses.
