Eye lenses were introduced into medical practice by the German inventor August Müller, who himself suffered from vision problems. According to statistics, 125 million people in the world regularly use contact lenses. But what are the advantages and disadvantages of Muller's invention?
This method of vision correction is mainly used by young people who refuse glasses due to inconvenience in use and aesthetic unattractiveness. Today, contact lenses are worn even by those who have not encountered the problem of visual impairment, because they make it possible to change the color of the eyes to any one they like. There are even lenses that make your eyes look bigger!
Benefits of contact lenses:
- When using them, the field of view is not limited in any way, which cannot be said about glasses. For example, for drivers, this feature of contact lenses is a significant advantage;
- Weather conditions will not affect the lenses in any way. They do not fog up, rain and snow are also not a hindrance when wearing them; When using contact lenses, you can freely play sports. With glasses, this is often a problematic process, because they can simply break or get in the way, not allowing you to move freely;
- Glasses can visually reduce the eye, but with lenses, the eyes always look natural;
- It happens that the degree of nearsightedness or farsightedness in the right and left eye is different. In this case, the lenses can easily correct vision. When using glasses, if the difference between the right and left lenses is more than 2 diopters, the person will experience severe discomfort, since it will be difficult for the eyes to cope with such a load;
- Thanks to toric contact lenses, even a complex form of astigmatism can be dealt with, in front of which glasses are powerless;
- People who are farsighted often have to wear two pairs of glasses for everyday use and for near work;
- One of the factors that often causes irritation in people who wear glasses – the appearance of glare on their lenses. In this case, contact lenses are devoid of such disadvantages.
Disadvantages of contact lenses:
- The use of lenses is very costly from a financial point of view. For example, when purchasing glasses, no matter what the initial purchase price, they can last from three years or more. Contact lenses, on the other hand, require constant change, in addition, you will also have to purchase various means for their processing and disinfection;
- Here it will not be possible to manage simply by wiping the glasses, as in the case of glasses. Caring for contact lenses is much more complicated;
- Whatever one may say, the lens is a foreign body in the eye that requires close attention;
- If you decide to use contact lenses – get ready for the fact that you will often have to appear in the ophthalmologist's office.
Other features of contact lenses
In addition to correcting vision, eye lenses can also change the color of the wearer's eyes. Thanks to multi-colored lenses, it becomes possible to radically change the color of the eyes, and as a result, the whole image. Colors such as purple, blue and green are especially popular.
There are also more outrageous options: sparkling, fluorescent, and "cat" lenses. However, you should not wear the latter for a long time, alternate them with ordinary contact lenses. Who should not wear lenses? There is a category of people for whom the use of contact lenses is completely contraindicated. The reasons for this are all sorts of diseases (ptosis, acute conjunctivitis, HIV), as well as the use of hormonal drugs that cause dryness of the cornea.
Where can I buy eye lenses?
Today, buying lenses for the eyes is not difficult, because there are many stores with a wide selection of such products. But before you visit them, be sure to consult with a specialist who will help you choose the most suitable option for you.
