Abstract: glasses are the most common method to correct myopia. Parents must choose a regular hospital when taking their children for optometry. Let’s make up the methods of optometry and glasses for popular science children., The process of children’s optometry and glasses matching: 1. Check the dominant eye: during the inspection of binocular balance, make the adjustment of both eyes balanced. If it cannot be balanced, make the dominant eye slightly clearer., 2. Check eye position: the myopia degree of exotropia and exotropia should be fully corrected, and the hyperopia degree should be low corrected; The degree of esotropia and esotropia myopia was lower; The degree of hyperopia should be enough., 3. Check the adjustment force: the myopia degree with too strong adjustment force should be shallow and the hyperopia degree should be deep; The degree of myopia with weak accommodation should be deep and the degree of hyperopia should be shallow., 4. The astigmatism axis and degree shall be verified by using a cross column mirror. The astigmatism degree along the rule is easy to be shallow, and the astigmatism degree against the rule shall be sufficient., 5. Eye balance., Types of children’s optometry glasses, 1. Obvious optometry: also known as subjective optometry, it determines the diopter according to the patient’s conscious vision after wearing glasses. Its characteristic is that the method is relatively simple, there is no need to dilate the pupils, the speed is fast, and the results can be known at that time. At present, most optical shops use this method, or combined with computer optometry.,
the process of children’s optometry
1. Check the dominant eye: during the check of binocular balance, make the adjustment and balance of both eyes. If it cannot be balanced, make the dominant eye slightly clearer.
2. Check eye position: exotropia and exotropia, the degree of myopia should be fully corrected, and the degree of hyperopia should be low corrected; The degree of esotropia and esotropia myopia was lower; Hyperopia should be corrected enough.
3. Check the adjustment force: the degree of myopia with too strong adjustment force should be shallow and the degree of hyperopia should be deep; The degree of myopia with weak adjustment should be deep and the degree of hyperopia should be shallow.
4. The astigmatism axis and degree shall be verified by using a cross cylindrical mirror. The astigmatism degree in accordance with the regulation is easy to be shallow, and the astigmatism degree in reverse shall be sufficient.
5. Binocular balance.
types of children’s optometry glasses
1. Obviously optometry: also known as subjective optometry, it determines the diopter according to the patient’s conscious vision after wearing glasses. Its characteristic is that the method is relatively simple, there is no need to dilate the pupils, the speed is fast, and the results can be known at that time. At present, most optical shops use this method, or combined with computer optometry.
2. Objective optometry: dilate the pupils before optometry to eliminate the regulatory effect of the eyes, which is particularly helpful for children under the age of 14 and improve the accuracy of optometry. However, the method is complex and needs to be examined by strictly trained professionals or ophthalmologists.
misunderstanding of children’s optometry glasses
1. “Famous teacher optometry” deceives customers: some stores with irregular operation often ask some newly recruited employees to optometry customers. In order to attract customers, sitting optometrists have been crowned with the titles of “senior optometrist” and “famous teacher”. Some miscellaneous stores completely hand over the optometry work to the computer. Without careful review and verification, they “finished” in more than ten minutes. The glasses prepared in this way will inevitably have errors. Some lenses are reversed left and right, or the optical center is incorrect and the axis position is wrong. When consumers use such glasses, they will have symptoms such as dizziness and dizziness; Severe can cause hypertension.
and
optometry is the most critical part of the matching process. The technical level of optometrists directly determines the visual effect of glasses. Inaccurate optometry and too deep matching make people dizzy, nausea and vomiting; The glasses are useless if they are too shallow. In fact, computer optometry can only give the approximate range of diopter. On the basis of computer optometry, the optometrist should also recheck the optometrist in the dark room, and then compare it with the computer optometry to get a more accurate degree, and get a more reasonable result according to the age and professional needs of the wearer. Even so, only after the wearer’s actual trial wearing and feeling comfortable can it become a formal prescription for glasses. In addition, all optometrists should have a work license – optometry qualification level certificate. In one day, A person’s vision error should be within 25 degrees (when he is too tired, the vision error is large). If it exceeds 25 degrees, the qualification of the optometrist or the glasses shop is questionable.
2. The lens is “fishy” : for coated glasses, a green or blue film will appear on the lens under the sun or light. The lighter the color of this reflective film, the better. If the reflective layer is gorgeous or there is no reflective film, it means that the glasses film is fake or not coated. Don’t underestimate the role of this film. With this film, you can effectively prevent the reflection of the lens, alleviate visual fatigue, and protect your eyes.
3. Shoddy frames are shoddy: in addition to good materials for lenses, the material selection of frames is also very important, which directly affects the beauty and comfort of glasses. The value of the frame accounts for a large proportion in the whole pair of glasses. This has also become the object of profiteering by some illegal manufacturers. As consumers generally do not have the basic knowledge and means to check and judge whether the frame is genuine or not, it is best to buy it in a professional large glasses store with good reputation. In addition, you can ask the store for the product certificate.
precautions for children’s optometry
1. From the perspective of safety, all students’ glasses use resin lenses without fragmentation to avoid eye trauma.
2. Mild myopia can only be worn when looking far away, but not when doing homework. However, if the astigmatism degree is high (above 100 degrees), it is best to wear
and
all the time in order to avoid visual fatigue and continuous deepening of myopia 3. As the myopia degree of students in the period of physical development may increase by about 50 ~ 300 degrees every year, the actual situation varies from person to person, so it is impossible for students to wear glasses for several years like adult glasses, It is generally required to have optometry at least once a year (such as during winter and summer vacation) and replace lenses or glasses as appropriate. Studies have shown that wearing blurred glasses for a long time (too shallow degree, inaccurate axial position and inconsistent pupil distance), the fundus retina can not receive the stimulation of clear images, but will accelerate the development of myopia.
“KDS”PS “4. For students with extremely high myopia, rapid deepening or anisometropia, they can check and match children’s special safety glasses under the guidance of professional ophthalmologists, which can not only avoid eye inflammation, but also achieve the best optical correction effect, but also slow down the deepening of myopia to a certain extent and kill many birds with one stone.
