Doing eye exercises for decades is a waste of time. Wear glasses to deepen myopia? Can online celebrity Eye Drops be used for a long time?
Bright eyes are fond of looking, smart and clear, and blazing with anger … As the window of the soul, people use many beautiful words to describe their eyes. However, with the change of living habits and the availability of electronic products, "small eyeball" has a "big problem". To make matters worse, there are some rumors about eyes that make things worse. June 6th this year is the 24th national "Eye Love Day". The reporter of Science and Technology Daily invited Ji ‘ang, director of ophthalmology department of Beijing Haidian Hospital, to sort out several major rumors about eyes and help prevent and treat myopia correctly.
Proverbs 1
Glasses can’t be taken off when put on, which will deepen myopia.
Many parents don’t want to wear glasses for their children, fearing that once they wear glasses, they can’t take them off, and they think that wearing glasses will deepen the degree of myopia.
In fact, on the contrary, adolescent myopia is axial myopia (the axial length exceeds the normal development length, causing distant objects to focus in front of the retina, and the retinal imaging is blurred to form myopia). Based on the current medical technology, axial myopia is irreversible and can only be controlled. Myopia without wearing glasses will inevitably lead to excessive eye adjustment and efforts to see clearly. As a result, it can only make eye adjustment spasm and visual fatigue worse, and then promote the deepening of myopia. The younger a child has myopia, the more likely he is to develop high myopia, and a pair of timely and appropriate glasses is very important to control myopia.
If children are found to be nearsighted, they can relieve their visual fatigue to a certain extent after optometry and glasses fitting in the hospital in time. Then, the development of myopia can be controlled by improving their eye habits, using their eyes for 30 minutes at close range, taking breaks for 5 to 10 minutes, ensuring indoor reading lighting and appropriately increasing outdoor activities (2 hours a day). Generally speaking, the annual progress of juvenile myopia is about 0.50D(50 degrees), which is basically the result of normal development. If it exceeds 1.00D(100 degrees), it is necessary to strengthen prevention and control measures.
Proverbs 2
Online celebrity eye drops have excellent effect and can be used for a long time.
The pursuit of bright eyes makes many people who love beauty pursue online celebrity eye drops with the same model, thinking that such eye drops can instantly relieve eye fatigue and fade red blood, which is beneficial to eyes after long-term use.
But is this really the case?
The main components of this kind of eye drops include naphazoline hydrochloride, oxymetazoline hydrochloride, tetrahydrozoline hydrochloride, chlorphenamine maleate, chondroitin sulfate sodium and menthol.
The reason why eye drops can remove red bloodshot is because the main component contains "adrenergic receptor agonist", which can effectively contract blood vessels and reduce eye congestion. Red blood goes away quickly, but it will come back. Long-term use will not only lead to dependence (if it is not red), but also lead to dilated pupils and dilated blood vessels (if the red blood is heavier), which may even lead to glaucoma. After being absorbed by nasal mucosa, these components will act on the whole body blood vessels, which will increase blood pressure and aggravate cardiovascular or endocrine diseases.
Preservatives in eye drops are also harmful to eyes. Generally, eye drops need preservatives because of repeated use. Many preservatives are harmful to the eye surface to a certain extent. If preservatives meet the national standards and are used for a short time, they will not cause permanent damage. However, if they are used for a long time, it is tantamount to killing the goose that lays the golden egg to relieve eye fatigue.
The principle of eye protection applicable to any crowd is not to overuse eyes for a long time. Generally, reading or using electronic products takes about half an hour. You should close your eyes and rest, blink or overlook for 5 to 10 minutes, and feel dry eyes. Artificial tears without preservatives are recommended.
Proverbs 3
Mydriasis optometry is harmful to eyes.
A more accurate name for mydriasis optometry is "cycloplegia optometry", which is an internationally recognized gold standard for diagnosing myopia.
Teenagers must have full mydriasis optometry for the first time. Theoretically, ciliary muscle accommodation exists in the eyes of people under 40 years old. The younger they are, the stronger the ciliary muscle accommodation is, and the degree of glasses given without mydriasis optometry is far greater than its actual degree. Even a considerable number of children have myopia of one or two hundred degrees by direct optometry. After full mydriasis, their vision is 1.0, but there is no myopia.
At present, the main cycloplegics used in clinic are: 1% atropine eye drops or eye ointment (long-acting for 21 days), 1% cyproterone hydrochloride eye drops (medium-acting for 3 days) and 0.5% compound tropicamide eye drops (short-acting for 6-8 hours). For children under the age of 12, it is strongly recommended to use 1% atropine for continuous eye drops for 3-4 days and then go to the hospital for optometry. After 3 weeks, the pupil will return to normal and the final optometry result will be confirmed.
Because there is photophobia and blurred vision during mydriasis, it is not recommended to read and write, so parents must pay close attention to their children’s vision and try to go to the hospital at the beginning of winter and summer vacations.
The optometry results after paralyzing ciliary muscle can make doctors know the ametropia of this eye with minimum deviation, and operating according to the regulations will not only damage the eyes, but also help to control the development of myopia.
Proverbs 4
Doing eye exercises can’t improve eyesight.
There is an online rumor that "doing eye exercises can’t improve vision, but many students massage with dirty hands, which leads to pinkeye and eye infection." Is it a waste of time to do eye exercises for decades?
Whether eye exercises are useful or not depends on its origin. On January 7, 1959, the Chinese Journal of Ophthalmology published the article "Preliminary Experience of Massage in Treating 49 Cases of Myopia". According to the memory of the old experts who participated in it, the Shanghai branch of the Chinese Medical Association conducted myopia research and carried out eye exercises in Shanghai.
At that time, it was clear that eye exercises can make students rest their eyes and relieve visual fatigue, but they can’t treat the high myopia that adults have already set. On the one hand, when doing eye exercises, closing your eyes can make your eyes rest properly; On the other hand, massaging the acupoints around the eyes can dredge the meridians, improve and promote the blood circulation of the eyes, and eliminate and adjust the eye tension; In addition, eye exercises and soothing music can also relieve mental stress to some extent.
In recent years, some researchers have conducted a study on the intervention of eye exercises on young people with mild myopia, and observed the changes of vision with the international standard eye chart two months later. The results show that the effective rate of eye exercises in the intervention of mild myopia is as high as 85.4%. According to an article published in Medical Theory and Practice, similar results were observed in the experiment on the prevention effect of new eye exercises on students’ low vision, and the total effective rate of new eye exercises was 86.4%.
Proverbs 5
Eye patch, massage instrument and functional glasses can cure myopia.
Various eye patches, eye masks, massagers, physiotherapists, functional glasses and other products that claim to cure myopia emerge one after another. Many people are confused by the advertisements of merchants, thinking that these products can cure myopia as long as they are used for a long time.
In fact, axial myopia is irreversible, which means that axial myopia cannot be cured and can only delay its development. When teenagers have axial myopia, they all have the illusion of exceeding the actual myopia degree to a certain extent due to accommodation spasm. It can be improved by correct mydriasis optometry or proper rest under the guidance of doctors. Many illegal organizations and businesses use this simple medical knowledge to over-publicize the concept of curing pseudomyopia.
Take the eye patch as an example. National Medical Products Administration has never approved any eye patch with myopia treatment effect. If consumers go online to check their production batch numbers and functional applicability, they will find the rhetoric of unscrupulous merchants stealing the concept. Therefore, consumers are advised to check whether the products have been approved as medicines and medical devices, and whether they have obtained the approval of medical devices before deciding whether to buy them.
