Contact lenses, medically known as cornea contact lenses, are more accessible to many users than frame lenses. So, what are the channels through which people pick contact lenses
Contact lenses sold online, journalists, chen fei bo
This morning, journalists called for answers to a question-and-answer type of app in a given life. In half an hour, 13 netizens answered the journalists' questions, six of whom chose internet purchases, five of whom chose real stores, and two of whom replied: “for the first time, they should go to the hospital to buy them.”
In a subsequent interview with a number of citizens, jadanqu told reporters that “i've been wearing invisibility for almost 20 years, and since that year i have only been able to go to four houses, two glass bottles have been baptized daily, and now all kinds of brands, series, colours, years, seasons, months, two weeks, sundays, day-to-day. The lenses are also becoming more sophisticated and comfortable."
Journalists have learned that most of them are working people who go to chains to buy near-sighted contact lenses; most of them are students or young people who have just entered the workplace, who prefer japanese-korean makeup, either near-sighted or flat; and most of them go to glasses stores or grids around schools, mostly students who buy beautiful pupils。
Through in-depth communication with users who buy contact lenses on the internet, journalists have learned of a type of internet purchase that is very popular with both businesses and users — to pay for a mail test. Journalists were searching for four words yesterday on a web-based buying platform for “pay-for-mail test” and e-mailed a large number of “nine nine-packs a day” commodities, with a common brand, and 9. 9-dollar parcels could even buy a box of five-day pupils' lenses. Since the majority of the population does not have the same degree of eye vision, there are no quantitative limits to such parcels. In other words, the payment of $19. 8 will make it possible to buy two boxes of pupils, which will make it possible to change every day of the week。
In interviews with journalists, it was found that the form given each time such mail tests were paid was different. Zhang xihui, director of optical opticals, first hospital, xian city, told reporters that “the proper use of contact lenses can make life easier for people and the proper use of contact lenses is more beneficial than bad. However, contact lenses are medically called amphibious amplifiers, which are directly exposed to the amphibians, and are therefore not only commodities but also medical devices. The total cost-saving challenge to the new product, which is not necessarily a safe product for itself, is at great risk.”
Whether it's day throw or year throw, conservation is more important than choice
Whether it is on the internet or in real stores, it is believed that every person who has bought contact lenses has faced the difficulty of choosing “day throw” or “year throw”. In response, director zhang said: “in addition to eye conditions and medical instructions, the wearing of contact lenses requires attention to the duration of the product itself. These factors, such as the type, material and duration of the different products, have been identified at the time of production and each has its advantages and disadvantages, which consumers should comply with. When choosing `day throw' or `year throw', users are free to decide on the basis of the usual use of scenery. It must be noted, however, that the eyes are very precious and precious organs and that conservation is more important than choice in the broader context of `qualified products'.”
Select contact lenses, use safety, reporter chen feibo
During the previous interview, journalists collected a number of questions about contact lenses and director zhang provided comprehensive research and answers。
Citizen yan dan asked: “the one i bought for the season was black and blue, and when i changed it, the color of the lens was much lighter than the new one. Is it true that contact lenses fall in color?"
Director zhang xiaohui: “the eyes doctor often refers to the popularly known pupils as cosmetics, which are popular with young people because they add colours to the lenses. In accordance with its production process, coloured and sandwich craft. Color colours do exist, and they are now phased out by mainstream processes. It is recommended that the municipality be elected to purchase a formal product of the sandwich process.”
Citizen zhang chul asked: “most recently, a brand-named daily contact lens called water gradients is on fire online, and many netizens say it's `real water feeling, sleep and wear it.' 'although the price is not low, but because it's a big brand and it's a good internet rating, can you really wear it and sleep?'
Director zhang xiaohui: “for contact lenses, the surface is high in water, the lens is high in oxygen, the lens is soft and does improve the comfort of the user, and there are even `day and night' contact lenses on the market. But as an ophthalmologist, i would like to remind you that you can't let your eyes go because you've improved your lens. My advice is not to wear sleep even if it's marked `day and night'. In addition, the basic arcs, materials and processes of the lenses affect the comfort of wearing them.”
Citizen chen xiao dan asked: "is it true that you're wearing contact lenses for barbecue, and you're going to roast them in your eyes and then you're going blind?"
According to director zhang, “the high temperature that human skin can withstand when eating barbecue does not lead to the melting of contact lenses. It is possible to destroy contact lenses (e. G., the flames of the barbecue equipment suddenly come out, the hot oil flashes into the eyes, etc.) only when the heat suddenly hits the heat, but when it comes to the barbecue, the near-heated temperature accelerates the water evaporation of the lens surface, drying and discomfort. It is better to wear frame glasses at this time, out of love. Besides this, baths, hot springs, etc. Are recommended not to wear.”
Contact lenses are not accessible to everyone, and they are widely worn, for example, by persons suffering from eye disease, severe trachoma, conjunctivitis, carnival, tear bladderitis, drierness or glaucoma until the disease has disappeared. In addition, the hands of people with influenza tend to carry a large number of pathogens that can easily enter the eye during the removal and wearing of contact lenses, leading to infection. Many of the medications used to treat colds contain elements to suppress tears. It is easier to wear contact lenses at this time, when frame glasses should be changed. When riding at long distances, the air accelerates the convection, which reduces the moisture of soft contact lenses, the lens becomes dry and hard, and the eyes feel uncomfortable. For a long time, hardened lenses are more likely to damage the cornea, causing eye pain or bacterial infections。
Journalists looked at the information and found that, because of the need to contact the corneas, contact lenses did cause some damage to the upper mantra, and there were reports that the skin of the cornea had been debilitated by wearing contact lenses. However, there are few serious consequences for the correct and intermittent wearing of contact lenses, as the peripheral cell damage is regenerative and does not leave a scar mark. However, doctors have also confirmed that the friction between contact lenses and the corneals can lead to long-term, chronic epipelagic damage and scarring. Thus, especially in the case of initial use, the examination must take place in the regular hospital, otherwise the cornea is damaged and paid for. In addition, contact lenses must be worn in accordance with the norms, even if the eyes are examined, and regular (half-yearly) visits to hospitals。
Director zhang concluded by saying: “the scale is only one element, and it is also necessary to examine all aspects of the environment as a whole. In everyday life, contact lenses are recommended for short wear, and frame glasses are recommended for replacement. In addition, amphibious amplifiers, which are available to both adults and minors, are to be used at the trina hospital, where the section operates, on a personal basis
