Let's take a closer look at this product, find out what it is, talk about the dangers and benefits of contact lenses, how to properly dress and operate them.
What is a contact lens: what are they invented for, advantages and disadvantages
Wearing glasses, even an adult, not to mention the child, will feel uncomfortable. When walking, and even more active activities: running, jumping or just a sharp turn of the head and at all you can break our glasses. In addition, the lateral review is markedly limited. We are forced to always keep these factors in mind, because a little something - we will have to spend again.
The developers took into account all those inconveniences and launched contact lenses that nobody else except you will notice, having a 100% review and allowing you to stand out, forgetting that you have any problems with vision. It would seem - here it is, the ideal. But no, like any market product, even if used in ophthalmology, he has his own shortcomings, often quite significant:
- First, the price. Really quality contact lenses cost as glasses, but require a systematic replacement, due to wear and tear. The period of such replacement is different, depends on the quality of execution and can vary from 1 week to several months;
- Do not forget that the body perceives any extraneous object that comes into contact with our bodies as a foreign matter. Flexible glass is not an exception, because they affect the most important sense organ - the eyes. Therefore, allergic reactions, inflammation and rejection are possible;
- They need to be taken care of, added to special solutions, so that they do not restrict the necessary supply of oxygen to our eyes;
Harm and benefit of contact lenses, reviews
If you do not follow the instructions of the ophthalmologist, change the lenses at the right time, wear them without cleaning them, then, naturally, get to the vision problem, also an infectious or other disease, for example, corneal erosion, edema, conjunctivitis, syndrome "Red eye". The list can be continued, but the point is that, like any medicine, it must be taken correctly. As written above, the contact lens, even the most modern, partially limits the flow of oxygen to the eye, which can cause illness.
Despite certain risks of wearing, reviews about the quality representatives of this product, that of doctors, that patients have positive. Constant wearing with observance of the rules of use will allow not only to restore vision, but also contributes to the treatment of "false" myopia, resulting from overstrain of the eye muscles. In addition, we often forget glasses, remove them, always put them somewhere, because of what we leave on the street without them or we go by car, squinting, looking for traffic lights, signs, pedestrians. All this does not contribute to treatment. Put on the eye lens of permanent wearing, in which you can even sleep - just do not lose.
