For children who are wearing OK lenses (keratoconus) and RGP (rigid oxygen permeable corneal contact lenses), there is no doubt that when they go out, they need to enjoy the convenience and comfort of OK lenses and RGP, the comfort of the breeze at night, the comfort of sleep, and the fantastic beauty of summer in the daytime, at a glance …… Here, Dr. Song Fengwei from the Department of Ophthalmology of the First People’s Hospital of Huzhou reminds all parents and students that OK lenses and RGP are relatively rigorous medical products, which are different from ordinary soft contact lenses and require medical professionals to guide the examination. Here, Dr. Song Fengwei from the Department of Ophthalmology of Huzhou First People’s Hospital reminds mothers, fathers and students that OK lenses and RGP are rigorous medical products, which are different from ordinary soft contact lenses and need to be dispensed and followed up regularly under the guidance of professionals in the medical institutions, and because of the strict requirements for the use of their materials, there is a lot of attention to pay, especially when you go out on a trip. Take keratoplasty lenses as an example. 1. During flight, OK lenses are safer to carry with you. Children and parents who choose to fly on trips should pay attention to the fact that the temperature of the airplane in the 10,000-meter high altitude check-in cabin is as low as minus 35-50 degrees (whether through the Antarctic or the tropics), which can instantly freeze and shatter the lenses preserved in the care solution, so OK lenses must be carried along with you, and do not be checked in. Furthermore, the airport staff of the violence of the baggage wrestling and luggage easily lost (international flights you know). Large bottles of care solution in the check-in box no problem. 2, travel OK lens soaking and cleaning can not be ignored. In regular review, many children’s duplex box inside the care solution as usual at home, just full of lenses, so it is easy to appear that the lenses are sometimes attached to the lid or on the wall of the box, not immersed in the care solution, and can not play the role of disinfection and cleaning. Traveling outside, no matter whether it is a review or to travel, must remember to pour more care solution, children do not not spare care solution, if because of the care solution and lead to lens care is not in place, but the loss is not worth it! The service life of OK lenses is generally 1-2 years, when traveling, because of the contact of the outdoor environment for a long time, the cleanliness needs extra attention. Most OK lenses are manufactured to be dry and placed in containers, and in actual normal use, OK lenses need to be replaced with fresh care solution every day to soak (clean and disinfect the lenses). If you are traveling for a long time, but do not wear them and keep them at home, you can wash and dry the OK lenses and put them in the duplex box. 3, sunbathing is healthier! What to sunbathe? Of course is the sun care package! Some children in the review over, we will find their own prepared lens care package will be a little moldy or have a small black (white) points, this time is the need for cleaning and drying. When you go out, remember to dry the care package to avoid the humidity of the local environment or accidentally splash wet. 4, encounter special circumstances it is best to consult a doctor in a timely manner or short-term stop wearing in wearing lenses, be sure to wear lenses inside drops full of moisturizing eye drops before wearing lenses, wear lenses must pay attention to the lens can not be under the air bubbles. If you can prepare anti-infective eye drops (such as colbitol eye drops) in advance before traveling, and if eye redness or eye pain occurs occasionally during wearing lenses, don’t be overly nervous, consult the doctor in charge or stop wearing lenses for two or three days, and make an appointment with a doctor for review at the end of the vacation.
