Summer vacation is here, for primary and secondary school students, this is a good time to “eye care”. The first thing you need to do is to go to a qualified eye hospital and find a specialist for a scientific fitting and evaluation before wearing glasses to avoid adverse reactions. The professional hospital is only qualified to fit Teenagers can choose OK lenses to control myopia, in order to slow down the growth of the eye axis. Usually the first day of wear can drop 175 degrees, 200 degrees or less after wearing a night of daytime vision can be restored to about 1.0, 500 degrees also only about a week to achieve the effect of no myopia. The OK lens fitting is a medical practice, the Ministry of Health expressly provides that only hospitals with fitting qualifications and professional doctors can carry out, the general opticians and the so-called myopia treatment institutions, are not hospitals, not for the patients casually fitting. In recent years, the new OK lens in the material oxygen permeability, CNC production technology, lens design and fitting has been greatly improved, as long as the myopia within 500 degrees, regular astigmatism within 150 degrees of the patient by the professional doctor’s assessment of the standard use of OK lens, the patient according to the requirements of the operation and regular review, generally will not appear eye disease. It is recommended that wearers open their eyes every day after waking up to see if there is any discomfort, and after removing the lenses to see if their eyes are red and swollen, and if their vision has decreased, they should see a doctor as soon as possible if they feel any stinging, redness or loss of vision. The first thing you need to do is to use a soft contact lens solution. OK lenses, like soft contact lenses, need to be soaked in a solution after removal, so some people simply use a soft contact lens solution to soak OK lenses. The hard and soft lens care solution cannot be mixed, OK lens users should buy special hard lens care solution, daily replacement of the care solution in the mirror box, open the cap when the cap is placed upwards, so that the bottle does not touch the fingers, lenses or mirror box and other objects, contamination of the care solution. Soak and disinfect the case once a week, and replace the case once every 1-3 months. If the bottle is not used up after 90 days of use, it should be thrown away together with the bottle. If the solution becomes cloudy during the normal trial period, stop using it immediately if you feel irritation, redness or swelling in your eyes. What is OK lens OK lens is the abbreviation of keratomileusis, is a new youth myopia prevention method, according to the principle of corneal plastic, with high oxygen permeable RGP rigid material to measure the “eye” custom, the user only need to wear at night when sleeping, daytime get up to take off can change the shape of the front surface of the cornea, reduce myopia and astigmatism. The actual fact is that you’ll be able to get a lot more than just a couple of hours to get a lot more than just a couple of hours. If you don’t wear glasses, some children get too close when looking at near objects and squint hard when looking at far objects, resulting in long-term pressure on the cornea from the eyelids, which can easily cause visual fatigue and increased corneal astigmatism. So myopia deepening is mainly related to eye hygiene and genetics, wearing frame glasses will not deepen myopia.
