Contact lenses - excellent vision without glasses Today, there are a lot of people who have vision problems. But not everyone uses glasses.. Most people prefer contact lenses for vision correction.. What are their advantages over glasses and do they have disadvantages? Read in the article.
Benefits of Contact Lenses You still can't decide whether to switch to contact lenses or not? Then let's list their main advantages.
Contact lenses (see a large selection of them at https://dom-optiki. ua/ru/catalog/135-kontaktnye-linzi) do not “distort” vision. When using contact lenses, it is completely natural.. Vision does not "
Contact lenses provide a wide range of vision, including peripheral vision.. And all because the lens moves with the eye.
Contact lenses, unlike glasses, are absolutely invisible to the eyes, so they do not change the appearance in any way..
Contact lenses can be easily fitted even to people who have a large difference in diopters.
Contact lenses will never fog up during sudden changes in temperature, from which glasses are not insured.
Well, the last advantage of contact lenses excludes any “maybe”, when choosing what is better to wear - “lenses or glasses”. We are talking about colored contact lenses, with which you can not only ensure good vision, but also change the color of the eyes - from brilliant blue to honey.
Types of contact lenses If we talk about soft contact lenses, they are hydrogel and silicone hydrogel. What is the difference?
• Hydrogel lenses contain a high percentage of internal moisture, which ensures a comfortable fit on the mucous membrane of the eye. At the same time, they pass oxygen to the cornea weakly.. For this reason, hydrogel lenses cannot be worn for more than 12 hours, and it is strictly forbidden to sleep in them.. Otherwise, corneal hypoxia may develop.. Therefore, it is better to choose a hydrogel lens with a minimum thickness to ensure maximum oxygen permeability..
• Silicone hydrogel lenses have no oxygen permeability problems.
And all thanks to the existing silicone, the structure of which provides the cornea with the necessary oxygen. This allows you to wear contact lenses continuously for several days.. The only drawback of such lenses is their relative rigidity, which can cause significant discomfort in the eyes..
Going to the optician for contact lenses, do not forget to consult an ophthalmologist. Since improperly selected contact lenses can not only not help in correcting vision, but also seriously harm.
