With glasses for children, get out of seven major misunderstandings
Summer is the peak period of students with glasses.Experts point out that there are universities in the small glasses. Before matching the mirror, you must figure out a lot of precautions and pay attention to science.
Misunderstanding 1: "Equisis can" poor quality
In the past few years, the glasses shop on the streets of Beijing in Beijing to attract customers, many of them have made "Equation" sign, but because some merchants produced the "Liquid" glasses, there is a quality problem in the glasses, "Li et al."Vocabulary is criticized.
During the visit, the reporter found that although there are fewer brands that are "erected", some glasses shops still take the fast route.For example, at Panjiayuan Glasses City, the reporter visited the glasses shop that as long as the current glasses we wear are comfortable, they can be matched directly according to this degree, no optometry is required.And it means that it can be done on the spot. It doesnt take too long for a long time. It is ten minutes, and at most half an hour.This cant help but murmur in their hearts, isnt this "waiting for"? Is such glasses wear it?
Tang Ping, the optometry and mirror center of Beijing Tongren Hospital, pointed out that with the advancement of science and technology, the "equal" can also ensure the quality of the glasses.However, the "can be equal" here does not mean buying ready -made glasses on the spot, but a kind of emergency service.In the case of relatively complete amount of the lens, and the current optical lenses are computer processing, cutting it into the shape of a suitable mirror frame, so if you need to add emergency services, you can make the quality within two hours.Guaranteed glasses.In the past, it was mainly manual grinding lenses. If the glasses were made in a short time, it was prone to major errors.
However, some special lenses, such as high degrees (such as seven or eight hundreds), and astigmatism exceeding 250 degrees. Because there are few lenses, it is often necessary to make special customization, and generally cannot be urgently made.Therefore, if the "preferably" businesses are still manual -based lens grinding methods, consumers must be careful.
Misunderstanding 2: Patching the pupil distance between the mirror
The reporter found in the interview that if the mirror person cant come, the staff of the New World Glasses Store, Treasure Island Glasses East Fourth Store, and Ruichang Mingming Mirror Center have made it clear that if there is no astigmatism and other issues, as long as the light test of the wearing glasses is provided, the light test of the glasses is provided.The degree and pupil distance can match the mirror.However, at the Fumeida Glasses Store, the staff said that "the degree can be directly equipped with the mirror, and the pupil distance is almost the same." However, the staff also said that if the pupil distance is not suitable, you can debug again.
Experts point out that a pair of qualified and comfortable glasses depends on the two factors: one is whether the optometry is accurate, and the other is whether the glasses are qualified.
In addition to the accurate optometry, various technical parameters must be reached when the mirror is equipped. The pupil distance is one of the key to preparing qualified glasses.The pupil distance measurement is inaccurate, and it is easy to cause many problems such as the distance deviation of the optical center and the vertical deviation of the optical center. Wearing this kind of glasses will not only eliminate visual fatigue, but will cause deformation, clear weakening, or even dizziness, nausea, vomiting, eye swellingWait.
Misunderstanding 3: The more advanced the optometry equipment, the better
The reporter also found in the visit that whether it is the hospitals ophthalmology department or the glasses shop, some of the places where optometry and mirrors are used are traditional vision tables, and some are computer projection instruments and equipment.This difference makes people whispering: Will the more simple optometry effect, the less accurate the equipment?
In this regard, experts point out that computer projection is a relatively modern device, which is less affected by the light in the environment; and the traditional vision gauge must ensure that the light is sufficient to meet a certain lighting conditions.As long as it meets the strength of the light, the accuracy of the two optometry methods is the same, so consumers do not have to worry.
After the consumer conducts optical tests, consumers often use the optical optical glasses to buy glasses elsewhere with optical optical glasses.In this regard, ophthalmologists remind people that the production and optometry of glasses are equally important. Therefore, it is best to use the pupil distance mirror to ensure the quality of the glasses after optometry.The qualified glasses should be comfortable after putting on it, clear vision, and not dizziness.
Misunderstanding 4: Time to spend time is not necessary
In many glasses shops, mirrors are directly equipped with glasses after optometry, and they are worn when they are worn. They often ignore the aspiration of the datum.Because of worrying about the loss of customers, or in order to improve the efficiency of work, many glasses shops will save the steps of dungeon.For example, at the Ruichang Ming Mirror Center and Fumeida Glasses Store, the staff said that it is not the first mirror, and there is no need to scattered.
In this regard, ophthalmology experts do not agree that although the pupils increase the mirror time, the degree of the mirror can be more accurate.Sandworthiness can help the mirroring person to determine whether there is a pseudo -myopia, so the degree of glasses will be more accurate.Moreover, because human eyes have self -regulating ability, even patients who have been myopia for many years may have pseudo -myopia.In the past, patients who had stable vision but had declined in vision in the near future, and the students who had just experienced heavy reviews had just experienced a heavy review. Do not ignore the whole step of the database before matching the mirror to eliminate false myopia.Generally speaking, children under the age of 12 and far -sightedness generally need to match the mirror after three days of scattered pupils.Others only take about 40 minutes of pupils.
Experts remind students of summer mirrors that it is best to go to the ophthalmology department of the regular hospital to conduct dotytic optometry before matching the mirror, and wait until the pupils are reduced to normal before audition.Especially for young people with the first mirror, they must go to professional institutions to perform optometry, datums, and mirrors.China
Misunderstanding 5: Restricted lens is suitable
The reporter found that there is also a gradient myopia lens in some glasses shops, and there is a difference between looking at the degree and the degree of looking at the distance.This kind of optical lenses are particularly recommended to students with immature eyes and unstable myopia, and the price is higher than ordinary lenses.Sales staff said that this kind of lens mainly uses the middle and lower part of the lens when looking at nearby, so the number of lenses in this part is lower; and when looking at the distance, the vision passes the middle of the lens with a slightly higher degree.
However, experts remind that it is not necessary for everyone to choose this gradient lenses. This lens does not have the effect of protecting the vision for everyone, and it may hurt the vision for some people.Because this kind of lens has high requirements for self -regulation of the eyeball. If the eyeball self -regulating ability is limited and there are problems such as regulating lag, it is not good for this lens to be good for vision health.Therefore, with this lens, you must first perform a professional ophthalmology examination to see the personal situation, that is, the self -regulating ability of the eyeball, such as strabismus patients cannot be matched with this gladsses.
Misunderstanding 6: The more functions of the glasses, the better
In addition to gradient lenses, the optical lenses have also been attached to many functions, such as coating, radiation resistance, UV prevention, etc., and the higher the optical lenses, the higher the price.So, are these functions necessary for consumers to choose?
Experts point out that coating lenses are desirable. This lens can reduce reflection, increase the clarity of things, and protect eyes and vision.UV -proof lenses are also good for preventing strong ultraviolet damage in summer. Strong ultraviolet rays can cause corneal damage to human beings, and even cause younger cataracts. Elderly people may have macular degeneration if they are severely damaged by ultraviolet rays.
Experts also remind parents to consider the material of the lens when matching glasses. The optical lenses are generally divided into resin lenses, glass lenses and crystal lenses.Because children and adolescents are relatively easy to move, it is recommended to use resin lenses when matching mirrors, which is light weight and strong anti -falls.
Misunderstanding 7: sunglasses style is more important than quality
In the summer vacation, many glasses shops discounted and launched a wide range of sunglasses. Although the quality is average, it is very popular with some fashionable students.
Doctors remind students that good sunglasses can protect their eyes. Infinite sunglasses not only have no anti -ultraviolet function, but also expand their pupils for a long time, increasing the light in the eyes, and increasing eye damage.Therefore, buying sunglasses must not be cheap.Do not pursue a variety of bright or alternative colors in color. It is best to choose traditional colors such as tea colors and dark green to better protect your vision.
In addition, adolescents with myopia and astigmatism may increase the quality of imaging due to the expansion of the pupils, so they must also choose sunglasses with caution.
Love tip
1. Beware of online purchases to charge in order to charge
Nowadays, online shopping is very popular, low prices, and can find some good things.Today, there are more outlets for glasses, and consumers without astigmatism, as long as the degree and pupil distance of myopia are provided.However, experts remind that glasses are also special consumer goods. When buying online, you must polish your eyes to avoid charging and damage to your vision.
2. Ill myopia should be matched in time
Experts point out that in teenagers who have just discovered myopia, there is a common psychology that they are neither willing to accept the facts of myopia or to match glasses.Even with glasses, they are unwilling to wear because of trouble or beauty.Experts point out that myopia is divided into pseudo -myopia and true myopia, so it needs to be identified through datums.Once diagnosis is myopia, we must match the mirror as soon as possible to protect the vision, and wear glasses as much as possible when using the eyes to protect vision and alleviate vision fatigue.
3. Correct vision should not be too high
Some students pursue the clarity of vision when they are equipped with a close -up mirror, and even want to correct the vision of 1.5.Experts remind that young people should not reach 1.5 with close vision mirrors, otherwise dizziness, eye bloating, eye fatigue and other conditions may occur after the mirror is equipped. Generally, the corrected vision can reach 1.0 or 1.2.
