Currently, a large percentage of the population has vision problems. Some, not embarrassed, go to the doctor so that he makes the correct diagnosis and prescribes glasses with the necessary diopters. But many have complexes about this, they don’t want to wear glasses, and so the visit to the optometrist is postponed, and the problem is exacerbated. Contact lenses may well solve this problem, with their help you can correct your vision. By the duration of wearing, they have different terms, in the article we will try to figure out what are the lenses of long wearing and what are their advantages and disadvantages.
Types of lenses for the duration of wearing
Since the appearance of the lenses, they are all divided into several groups:
- Daytime, that is, used in the daytime, and at night they must be removed.
- Long-wearing lenses are those that you can not remove for a certain time.
- Flexible wearing allows you to wear lenses for three days.
Before you go shopping for lenses, you need to visit a doctor to discuss which lenses are best suited to your vision and general body characteristics.
Danger of over-lensing
Those who prefer contact lenses to glasses should know that the rules for their use must be observed, because there is a great risk of infectious and chronic eye diseases.
This is especially true for those who use long-wearing lenses. Each type of lens has not only its term of use, but also the rules of use. All this is developed taking into account the following indicators:
- In the process of wearing on the lenses, various deposits are formed, for example, protein and fat.
- After some time, irreversible changes begin in the material from which the lenses are made. Each type has its own period, so you need to know about it. For example, if the lenses can be worn continuously for a month, and you only wore them a couple of times, then after 30 days you still have to replace them with new ones.
- The cornea of the eye, which is covered with a contact lens for a long time, begins to suffer from a lack of oxygen, which can lead to irreversible changes inside the eye.
Lenses that have different periods of use differ from each other in just different permeability to oxygen, which means that they are made of unequal materials.
Varieties of Long Wear Lenses
Since such lenses imply their long stay in the eye, then, accordingly, completely different requirements for the composition of the material should be presented to them. Long-wearing lenses can be made from the following materials:
- Silicone hydrogel lenses. The successful combination of the two materials makes these lenses soft and comfortable at the same time, as well as oxygen-permeable. Another advantage of silicone is its greater resistance to the formation of various deposits.
- Rigid gas-permeable lenses also allow oxygen to pass through perfectly, but they are more rigid, which adds some discomfort when worn, not everyone can get used to it.
What lenses to choose for long-term wear, each for himself decides for himself, but after consulting a specialist.
Benefits of Using Lenses
Many still prefer the old fashioned way to wear glasses if there are vision problems, but most of the population does not lag behind modern technologies, which firmly defend their rights in medicine. Those who have tried contact lenses can name a lot of advantages, among which I would like to name the following:
- Good quality vision correction.
- An excellent view of visibility is preserved, it is enough to just squint your eyes without turning your head to see objects located on the side.
- With a sharp change in ambient temperature, the quality of visibility does not change.
