Few people are familiar with such an invention as hard contact lenses. Sounds a little scarier than, for example, soft lenses. Although it may not seem so at first glance, rigid lenses pass oxygen better than the most famous soft lenses. Many people prefer to use silicone hydrogel lenses, which are known for their safety, but they also allow less oxygen to pass through them than rigid lenses. Although most people are forced to use these lenses for he alth reasons.
Another benefit of hard contact lenses is that they provide clear vision. They are also more durable, which means they will last longer. In terms of cost, they are cheaper than their counterparts.
Indications for use
Recommended to use hard contact lenses if the use of soft lenses does not bring any effect. And this happens in the following cases:
- A person has high requirements for quality and visual acuity. As a rule, high demands on vision are made by people working as operating surgeons, drivers, jewelers, etc.
- When astigmatism is detected. With such a diseasesoft lenses are unable to give 100% vision, as the very shape of the cornea of the eye changes.
- If the shape of keratoconus is changed.
- In the period after vision correction by surgery (such as laser correction of myopia). It happens that patients are not even able to wear lenses after surgery, and they are prescribed glasses.
Hard contact lenses. Operating Rules
If a doctor has prescribed vision correction with hard lenses, then after you start using this technique, you will need some time to get used to them. The adaptation period ranges from 5 to 7 days, for each person individually. In some cases, more time may be needed. Do not worry about wearing such lenses, because they do not cause any pain. To quickly overcome the feeling of discomfort after the start of using hard lenses, you need to wear them as often as possible. And do it even when there is no such need. The more often you wear them, the faster your eyes will get used to it. If you take a break, then again it will take time to adapt the eyes. Therefore, corrective lenses should be worn every day and should not be replaced.
How to store and care for hard eye lenses
Like soft lenses, hard lenses are worn directly on the cornea, so they require thorough cleaning and maintenance, as well as compliance with all operating rules. However, caring for hard lensesless difficult than for soft ones, since they are not overgrown with pathogenic fungi and other microorganisms.
Store them in a specially equipped container filled with a disinfectant solution. Compliance with this rule is very important, since the solution disinfects the lenses, and the container reduces the risk of deformation.
The most difficult thing in applying LCL is their initial selection. After all, each lens must ideally fit the surface of the eye cornea. In this case, special equipment is used, so the selection is possible only from a qualified specialist, even if these are decorative lenses for the eyes.
