You should wear glasses!
I hope the answers below will be helpful to you!
1. Are there better ways to protect your eyes besides eye exercises?
Answer: For young students, you also need to pay attention to writing and reading distance, which should preferably not be less than 30 centimeters; desk lamps should not be too bright, a regular 15-watt bulb is appropriate, and a three-band energy-saving lamp of 3 watts is appropriate. When using eyes for a long time up close, special myopia prevention glasses should be worn; the distance for looking at a computer should not be less than 60 centimeters, and the distance for watching TV should not be less than 3 meters. Eyes that are already myopic or have other refractive defects should always wear glasses with accurate degrees. Sleep time should not be less than 8 hours.
2 Can doing eye exercises prevent myopia? If already myopic, can vision be restored?
Answer: Vision loss caused by myopia cannot be restored. Eye exercises can only restore part of the vision loss caused by eye fatigue.
3 What kind of glasses can protect your eyes?
Answer: Wearing glasses adapted to the environment can protect your eyes. For example: wearing sunglasses under strong light; wearing distance glasses when mainly using distance vision; wearing nearsighted glasses when mainly using near vision; wearing computer glasses when mainly using computers; wearing dedicated electrical welding glasses during electric or gas welding...
4 What machines can treat myopia?
Answer: No machine can effectively prevent or cure myopia. The best way to treat myopia is to wear glasses.
5 Can true myopia be restored?
Answer: It cannot be restored. True myopia means the eyeball axis has become longer and cannot become shorter, thus true myopia cannot be restored.
6 Is wearing glasses harmful to the eyes?
Answer: As long as the method is appropriate, it is beneficial and harmless to the eyes. But currently most people use them improperly, resulting in deeper glasses over time and worse eyesight.
7 Should glasses be worn all the time without removing them?
Answer: Glasses should be worn all the time if they are suitable. However, different people have different refractive conditions and different uses of their eyes, so what kind of glasses should be worn and when to remove them varies from person to person. Glasses correcting hyperopia and treating amblyopia should be worn all the time. Other situations are more complex, and when to remove them varies from person to person and cannot be generalized. You must follow the advice of optometric experts (do not follow the advice of non-experts).
8 Is wearing someone else's glasses harmful to your eyes?
Answer: In most cases, it may be harmful, therefore, you should not wear others' glasses.
9 Where can I get glasses that protect my eyes?
Answer: Exhibition Road No. 12, Junming Myopia Prevention Center. Various types of glasses that protect the eyes and prevent myopia can be obtained here.
10 Are OK glasses beneficial to the eyes?
Answer: Little benefit, many disadvantages.
11 How do you fit glasses if there is a large difference in binocular vision?
Answer: It is indeed difficult to fit glasses if there is a large difference in binocular vision. Both improving vision and preventing strabismus, monocular vision, alternating vision, and astigmatism expansion need to be considered. Different people have different conditions, so the fitting methods also vary from person to person. Not only do the fitting methods differ, but the usage methods also differ and cannot be generalized. The fitting method can only be determined after an expert examination.
12 What are the benefits of anti-radiation lenses?
Answer: Anti-electromagnetic radiation lenses can reduce eye fatigue and its symptoms when using the computer for a long time.
13 If students who wear glasses properly protect their eyes, can their vision be restored?
Answer: Vision loss caused by myopia and astigmatism cannot be restored. Vision loss caused by visual fatigue can be restored. If the corrected vision gradually improves after wearing glasses, it can only be explained that the visual fatigue is gradually decreasing.
14 It is said that computers emit radiation, which is harmful to the eyes. Why are there still computer classes, and how can the eyes be protected?
Answer: The radiation intensity of computers is not high, keeping the eyes 60 centimeters away from the screen is harmless to the eyes. Being closer than 60 centimeters to the screen is harmful and can cause severe visual fatigue. Therefore, when using the computer for a long time, the eyes should not be too close to the computer screen.
15 Why do eyes "blur" when wearing glasses with high degrees?
Answer: Only when the degree of the glasses equals the refractive error degree of the eye will the eyes not "blur."
16 If vision decreases, how can it be restored?
Answer: Vision loss caused by visual fatigue can be restored after appropriate rest. If the vision loss is caused by myopia, it cannot be restored. Therefore, it is necessary to actively and automatically prevent the occurrence and development of myopia in advance to avoid vision loss caused by myopia.
17 Which method of protecting the eyes is the best and most effective?
Answer: Using the eyes at the correct distance; using the correct time, correctly fitted glasses, and correctly using glasses to protect the eyes is the best and most effective. Unfortunately, most people do not know these "correct" factors. Moreover, the "correct" factors for different people are not entirely the same. It is best to consult an expert for an eye examination and listen to the expert's opinion.
18 How is amblyopia formed and how is it treated?
Answer: There are multiple causes of amblyopia, the most common being refractive defects and visual fatigue. If amblyopia is caused by high hyperopia and astigmatism, wearing appropriate glasses starting at the age of 3-4 years and persisting until 12 years old can cure it. If amblyopia is caused by prolonged use of computers up close, moving further away from the computer screen, eating some vitamin A, ensuring adequate sleep time, and taking a break for a period can help return to normal.
19 At what degree of myopia is one considered to have myopia?
Answer: Myopia greater than 0.25 degrees can be considered myopia.
20 Is the condition of the eyes related to genetics?
Answer: The condition of the eyes is related to genetics. But there is no absolute or definite relationship. Genetic factors are only one of the reasons for the condition of the eyes. Eggs can turn into chickens, but it is only a possibility. If the temperature is not suitable, they cannot turn into chickens. Eggs placed in the refrigerator will remain eggs forever; placed in a pot, they become meals. The eyes have similar situations. Under conditions where myopia can occur, hyperopia can also turn into myopia. Under normal conditions, hyperopia can turn into emmetropia.
21 After finishing homework, the eyes are already tired. Can I still read extracurricular books?
Answer: After finishing homework, immediately do a set of eye exercises seriously, rest your eyes closed for 5 minutes, then wear myopia prevention glasses to read extracurricular books.
22 At what degree of myopia is it better to wear glasses? Should glasses be worn even for slight myopia?
Answer: It is better to wear glasses for myopia above 0.50 degrees. Wear distance glasses when mainly looking far, and near glasses when mainly looking near. This can protect the eyes and prevent the occurrence and development of myopia and myopia complications.
23 How is myopia, astigmatism, and amblyopia treated?
Answer: The best option is to wear glasses.
24 Is it harmful not to wear glasses if one is myopic?
Answer: Not wearing glasses if one is myopic cannot improve vision or protect vision. It is more harmful than beneficial.
25 For mild myopia, is it better to wear glasses regularly or not?
Answer: Mild myopia refers to myopia below 3.00 degrees. Below 0.50 degrees, there is no need to wear distance glasses, but near glasses should be worn; between 0.50 degrees and 2.00 degrees, distance glasses should be worn when mainly looking far, and near glasses when mainly looking near; above 2.00 degrees to 3.00 degrees, distance glasses should be worn, and there is no need to wear near glasses.
26 How can amblyopia be prevented, and how is it treated if already present?
Answer: Starting from the age of 4, wearing appropriate glasses can prevent and treat amblyopia.
27 What are the symptoms of astigmatism, and how is it formed?
Answer: Astigmatism is also a type of refractive defect. Visual symptoms include blurred vision, double vision, occasional dizziness and headache, and unstable vision. The causes of astigmatism are numerous, mainly due to genetics and physiological development before the age of 3, where the eyeball grows faster and the eyelid grows slower, causing uneven growth and development of the cornea.
28 Why do eyes deform after wearing glasses?
Answer: There are two reasons: One, myopia, especially moderate to high myopia, causes the eyeball axis to lengthen and the eyeball to enlarge. Regardless of whether glasses are worn, the eyeball protrudes more compared to when not myopic. For every 3.00 degrees of myopia, the eyeball protrudes by one millimeter. Two, glasses have a beautifying effect. Myopia of 3.00 degrees forms gradually over more than two years, with the eyeball axis lengthening by one millimeter and the eyeball protruding by one millimeter, happening in 3.00 stages. If glasses are not worn, no one would notice this subtle change. After wearing myopia glasses, the concave lens reduces the image of the eyeball, making it appear smaller. Getting used to it creates a visual standard. Removing the glasses reveals the actual eyeball, showing significant changes, making it seem larger. The higher the degree of the glasses, the more noticeable the change.
29 Is pupil dilation harmful to the eyes?
Answer: Using pupil dilation medication under a doctor's guidance is harmless to the eyes.
30 Are OO eye protection instruments really effective?
Answer: The function of OO eye protection instruments is to allow the eyes to be in the same state as walking while sitting still. If used to treat myopia, it only has a placebo effect. Since it cannot achieve simultaneous learning and prevention (prevention is needed during study but cannot be done, prevention cannot be done during study), its role in preventing myopia is limited.
31 Should glasses be worn while watching TV?
Answer: People with myopia should watch TV from a distance of 3 meters. Accurate distance glasses should be worn while watching TV. Not only can the picture be seen clearly, but it can also protect vision and prevent myopia-related complications. Watching TV without glasses is harmful to the eyes.
32 Is it good to wear glasses while running? Is it harmful to the eyes?
Answer: Wearing glasses while running is harmless to the eyes.
33 What can be done now to avoid needing reading glasses in old age?
Answer: Maintaining 2.00 - 3.00 degrees of myopia now can prevent the need for reading glasses in old age.
34 Is it better to look at distant objects or the sky after finishing homework?
Answer: Looking at distant objects is better than looking at the sky.
35 With low-degree myopia, if recent vision has slightly improved, can it be fully restored?
Answer: Vision loss caused by low-degree myopia cannot be restored. Better vision indicates less visual fatigue.
36 After continuous use of the eyes for how long should a rest be taken, and how long is the rest period ideal?
Answer: At a distance greater than 30 centimeters, emmetropic eyes or wearing distance glasses for reading and writing, students under 15 years old should rest for 5 minutes after 20 minutes of continuous use; students over 15 years old should rest for 5 minutes after 30 minutes of continuous reading. Using appropriate near glasses allows for 3 hours of continuous use followed by a 5-minute rest.
37 Is it okay to lie down and read with the eyes parallel to the book?
Answer: Lying down makes it difficult to maintain and keep an appropriate distance, even if the eyes are parallel to the book, it can easily lead to myopia.
38 Can we wear contact lenses at our age?
Answer: Middle and primary school students are best not to wear contact lenses. Wearing contact lenses can worsen myopia and trigger various eye diseases.
39 Can progressive multifocal glasses be worn for 3.00 degrees of myopia?
Answer: Progressive multifocal glasses are suitable for middle-aged and elderly people and not suitable for young students. They cannot prevent the occurrence and development of myopia. This conclusion has been confirmed by a large number of facts.
40 In what situations should glasses be worn?
Answer: Glasses should be used when the distance, time, and lighting match the function of the glasses. Wearing them correctly is beneficial, while wearing them incorrectly is harmful.
41 What consequences arise if the glasses prescription does not match the actual eye prescription?
Answer: A difference of 0.50 degrees has no adverse effects. However, a difference of 1.00 degree or more can have some consequences. For example, if the glasses prescription is 1.00 degree higher than the actual refractive error, the myopia degree is less likely to worsen, but distant vision will be poor, and near vision will be even worse; if the glasses prescription is 1.00 degree lower, distant vision will be slightly poorer, but near vision will be normal and feel comfortable, though the myopia degree is more likely to worsen. If the glasses prescription is 2.00 degrees lower, the situation will be different...
42 At what level of vision decline should glasses begin to be worn?
Answer: There are many reasons for vision decline. The cause must be identified first to determine whether glasses should be worn and what kind of glasses. If wearing glasses is intended to restore vision lost due to myopia, glasses should be worn when feeling that vision is insufficient. If the purpose of wearing glasses is to prevent vision loss caused by myopia, glasses should be worn when vision feels normal
