Introduction: As a delicate pig girl who has just turned eighteen years old, oh no, she is almost thirty years old, all kinds of transparent glasses and contacts of various colors and sizes are indispensable in daily life. So how to choose the healthiest glasses?What should I pay attention to when wearing **glasses?Today, the senior sister will tell you about the delicate girls and boys** glasses!
Contact lenses, commonly known as **glasses, the first** glasses, appeared as early as 1887 as a type of ophthalmic lens worn on the front surface of the eyeball. **Glasses can be divided into two categories: hard contact and soft contact according to the shape of the glasses, rigid contact lenses refer to contact lenses whose final form can maintain their shape without support under normal conditions, such as the well-known orthokeratology lenses. Wearing orthokeratology lenses can improve our vision in a short period of time, and it has the effect of inhibiting the increase of progressive myopia in adolescents.
Soft contact lenses refer to contact lenses that need to be supported to maintain their shape, such as various contact lenses, daily disposable lenses, and monthly disposable lenses. The traditional frame mirror is heavy and heavy on the bridge of the nose, and it is easy to forget to throw it away when you put it in your hand. In winter, the lenses fog up when you enter the house from the outside, and in the summer, you sweat and tend to slip down. Comparatively speaking, glasses are beautiful, convenient, and increase the field of vision, so now glasses have become the first choice for young people.
The deterioration of lenses has a direct relationship with our eyesight and eye hygiene. There are more than 20 parameters to evaluate the quality of contact lenses, including top power, light transmittance, radius of curvature, refractive index, etc., which cover many fields such as optics, geometric size, and physical and chemical properties of materials. It's just a small lens, but do you really wear it?The following points ** The incorrect use of glasses, are you also tricked!
Never take off your glasses.
According to the British "Mirror" report, Moore Gallia, who worked as an ophthalmologist at Solihull Hospital, shared a strange case in "optometry today", a 67-year-old female patient felt dry and uncomfortable eyes, thinking it was just simple aging or dry eye syndrome, and after examination, it was found that the eyeballs were covered with a layer of "blue substance", so she decided to perform cataract surgery, but the medical team actually removed 17 pieces of ** glasses that were almost folded together from her eyeballs. What's even more outrageous is that the doctor took out 10 ** glasses in the same eye during the second examination. Moore Galliai and the other doctors were incredulous, "How could anyone get so many things stuck in their eyes without noticing!."We've never seen anything like this before. ”
Senior sister, it's just spicy eyes when you think about it!!
If you don't take off your glasses for a long time, it's not only unhygienic, but the key is how uncomfortable it is!If I don't take it off for a few hours, I feel very dry, and I don't dare to try this kind of thing, let alone wear it for a few months or even decades and never take it off, I can't imagine it!I'm afraid that when I open my eyes, I will stick to my sister's ** dog eyes, and if it is serious, it may cause blindness.
Take off your glasses in water.
Many girls think that after washing their hands, they will be clean and hygienic, and they will be sterilized and disinfected with running water. In fact, since a few years ago, the British ** Optical Association began to put such a logo on the ** glasses sold across the country. What do I need to pay attention to when wearing **glasses?
Don't get wet!Don't get wet!
Don't get wet!
Important things said three times!But some people really don't pay attention.
Perhaps just removing the glasses after a hand wash without the hands being completely dry can lead to Acanthamoeba keratitis (AK). Acanthamoeba keratitis (AK) is an infectious corneal disease caused by Acanthamoeba protozoa, a single-celled protozoan microorganism that is widely present in all known water sources, tap water, seawater, swimming pools, groundwater, and saliva. In short, all water sources.
In fact, among the many infected people, blind people have been diagnosed in time and have been effectively **, and the more serious consequence is that because the early symptoms of AK are not obvious, they are often misdiagnosed as ordinary infections and cause delays**, once the Acanthamoeba protozoa continues to invade the brain from the eyes, it may even hurt the spine, causing paralysis and death!
Don't get wet" tips:
Although the ** glasses that make the eyes bigger and brighter are the gospel of beauty lovers, remember not to give up your health for the sake of beauty. Therefore, when wearing ** glasses, you must pay attention to hygiene and change them frequently. Finally, the senior sister also wants to tell you about other things to pay attention to when wearing ** glasses.
1 Do not wear soft** glasses overnight and remove them before going to bed. However, rigid glasses such as orthokeratology lenses need to be used in sleep and myopia at night.
2 If you take a plane for a long time, it is recommended to take it off**. First of all, high air pressure affects the curvature of the cornea, and glasses are easily deformed and damage the cornea. Secondly, the dry air in the cabin will cause the moisture on the surface of the eyeball to evaporate rapidly, resulting in a certain dryness. Thirdly, the protein components in the tears secreted by the eyeball are also prone to dry up, blocking the stomata and causing corneal hypoxia.
3.In terms of appearance, ** glasses are not as thin as possible. For soft glasses, thin glasses improve comfort, but their formability is poor, and it is not easy to wear correctly, and the lenses are easy to dry and dehydrate, resulting in cornea dryness, staining, and lenses are easy to break.
4.When I was a child, I felt that the more I wore glasses, the deeper my prescription would become. However, people who have a stable degree will not add depth when wearing ** glasses. Moreover, teenagers should wear rigid oxygen-permeable glasses, because the imaging effect is good, and they can also avoid the difference of glasses, so as to control the development of myopia.
5.So who is not suitable for wearing **glasses?For example, diabetics, pregnant women, and people with immune system diseases: wearing ** will affect the secretion of eye glands, making the eyes drier and drier. Myopic patients with irregular astigmatism and neovascularization at the corneal margin: not suitable for wearing soft ** glasses. It is also best not to wear it during menstruation, as the intraocular pressure increases during this period, and the area around the eyeball is easily congested.
If you really need to wear colored glasses, at least ask a doctor to see it, and then go to a regular optometry institution for glasses. The selected lenses require ultra-thin sandwich technology to truly isolate the pigment in the middle of the lens, which is as resistant to bacteria as high-end transparent daily disposable lenses. Whether it is online shopping or small store purchases, the pigment and lens uniformity cannot be identified by the naked eye. So either look for the brand or listen to the doctor.
However, the senior sister still feels that wearing frame glasses is more hygienic, and if it is inevitable to wear ** glasses, try to choose daily disposal. It is best not to wear it for more than 6 hours a day, and at the same time, disinfect it in the care solution for no less than 12 hours a day to effectively sterilize. After taking off the **, put on glasses in time to let the cornea breathe and absorb nutrients.
Do eye exercises to increase the number of blinks so that tears are evenly distributed on the surface of the eye. When you return from going out, rinse your eyes with running water in time. The senior sister thought about it, or quickly cut off the ** glasses in her eyes, and hurry up to do eye exercises, the large-framed mirror seems to be more suitable for me!
