Wearing contact lenses is always uncomfortable? How to purchase

      Nowadays, more and more people choose contact lenses rather than bulky glasses for image.

　　However, there are many "minefields" in the selection and daily wear of contact lenses, which sometimes make the wearer feel uncomfortable, resulting in dry eyes, poor vision and even eye infection. How to choose and wear contact lenses to avoid lightning strikes?

　　What do you need to pay attention to?

　　These people are not suitable for wearing contact lenses.

　　Contact lenses are not suitable for everyone. The following categories of people are not suitable for wearing:

　　First, patients with high intraocular pressure, severe dry eye, infectious conjunctivitis, diabetes and other systemic diseases and poor eye health are not suitable to wear contact lenses;

　　Second, they did not pay attention to personal hygiene and could not consciously check the eye condition of the crowd;

　　Third, people with allergies, especially those who are allergic to lens materials and components of nursing products;

　　4、 For people who often need to face sand and volatile chemicals in their living and working environments, wearing contact lenses may increase the possibility of eye damage.

　　In addition, junior and senior high school students who are still in the development stage can also wear contact lenses, such as OK lens, which is a high oxygen permeable rigid contact lens with a special structure design. Doctors will guide Chinese teenagers to wear it to control the occurrence, development and speed of myopia.

　　There are also some problems in young people's society. Because of the difference in the refractive state of both eyes, they are not suitable for wearing frame glasses and can choose contact lenses.

　　However, it should be noted that the beauty pupil should not be worn as much as possible. The oxygen permeability of the beauty pupil is relatively poor, and the quality level of the beauty pupil on the market is uneven, so it is easy to buy unqualified products.

　　Select appropriate contact lenses and pay attention to all parameters

　　When purchasing contact lenses, people who are suitable for wearing contact lenses must choose conventional products and also pay attention to the selection of contact lens parameters.

　　First of all, contact lenses must be accurate.

　　When wearing contact lenses, you also need to go to a professional institution for optometry to determine the accuracy.

　　If the wearing degree is not appropriate, long-term wearing may affect vision health.

　　In the case of astigmatism, if the degree of astigmatism is not high, regular spherical contact lenses can be used, but if the degree of astigmatism is too high, it is better to use contact lenses with customized astigmatism design.

　　It should be noted that contact lenses can not be purchased directly based on the known degrees of frame glasses.

　　Because the frame glasses are worn on the bridge of the nose, there is a certain distance between them and the cornea, which is called the lens eye distance. The degree of the frame glasses is different from the contact lenses directly worn on the cornea.

　　The selection of contact lens degree requires conversion of lens distance based on frame lens optometry.

　　The second is the base arc through the lens.

　　The base arc refers to the radius of curvature of the lens. The size of the base arc is related to the steepness of the inner surface of the lens. The smaller the base arc, the steeper it will be, and the tighter it will be in your eyes.

　　When the method of base arc parameters is not appropriate, it will reduce the comfort of patients. Therefore, it is necessary to study and select the base arc size of a contact lens according to the measurable parameters of corneal curvature.

　　In addition, the parameters of oxygen permeability and water content can not be ignored.

　　The better the permeability of oxygen, the more comfortable the cornea can breathe.

　　Generally, the thinner the lens, the better the oxygen permeability, and the higher the water content of the lens with large oxygen content. But because it needs to keep the lens wet, it will absorb water in the eyes, causing dry eyes.

　　Therefore, these two parameters need to be considered at the same time.

　　Different groups need to measure their own situation under the guidance of professional doctors.

　　Finally, in terms of comfort and safety, lenses with short discard cycles are relatively clean, which is unlikely to cause eye infection.

　　Daily care should not be sloppy

　　Select appropriate contact lenses, and pay attention to the care when wearing them at ordinary times:

　　First of all, the shell, wearing tools and other daily necessities of contact lenses need to be disinfected and replaced regularly, and the hands should be clean when wearing and selecting them;

　　Second, contact lenses must be removed during swimming, bathing and sleeping, otherwise there may be a risk of serious infection to the eyes.

　　In addition, after removing glasses, it is necessary to conduct research immersion disinfection by using different nursing solutions in a timely manner;

　　Third, the wearing time of each piece should not exceed 8 hours as much as possible. At the same time, pay attention to giving up the cycle. Do not let the lens be used beyond the time limit, and replace it regularly;

　　Fourth, if you have dry eyes and other symptoms, you can drop artificial tears without preservatives. If you need to take them out in time, please see a doctor if you feel serious discomfort;

　　Fifth, remember to go to the hospital for regular eye health check.
