The impact of wearing glasses on eye health: common misunderstandings and scientific explanations

With the increasing rate of myopia every year, more and more people need to wear Glasses to correct their vision. However, many misunderstandings about wearing glasses are still widely circulated among the public, such as "wearing glasses makes myopia worse" or "wearing glasses for a long time will make the eyes dependent". This article will clarify these common misunderstandings from a scientific perspective and answer the real impact of wearing glasses on eye health.

Myth 1: Wearing glasses will cause myopia to deepen

Misunderstanding analysis

Many people believe that wearing glasses will make myopia "deeper and deeper", and even think that not wearing glasses can slow down the deepening of myopia. However, this view lacks scientific basis. The progression of myopia is mainly affected by factors such as axial growth, genetics, and environment, rather than by wearing glasses themselves. The occurrence and development of myopia is mainly determined by genetic factors and environmental influences, especially long-term close-range eye activities (such as reading and using electronic devices) will accelerate the progression of myopia.

Scientific explanation

The function of glasses is to accurately focus light on the retina, thereby providing clear vision. When myopic patients wear appropriate glasses, they can effectively reduce the discomfort caused by blurred vision. If you don't wear glasses, your eyes will constantly try to adjust the focal length, which will increase eye fatigue and affect vision health. Studies have shown that wearing suitable glasses can reduce the burden on the eyes and will not directly lead to the deepening of myopia.

Myth 2: Wearing glasses for a long time will make the eyes "dependent"

Misunderstanding

Many people mistakenly believe that wearing glasses for a long time will make the eyes "lazy", thus forming "dependence", and once they take off the glasses, they can't see clearly. This misunderstanding may come from the actual experience of some people, that is, they feel blurred vision after taking off their glasses, which makes them mistakenly believe that it is caused by "dependence" on glasses.

Scientific explanation

The so-called "dependence" is not a manifestation of worsening eye health. Wearing glasses only helps focus vision and makes people see more clearly. After taking off glasses, the feeling of blurred vision is just a "habitual loss" of clear vision, and it does not mean that the function of the eyes is weakened. In fact, for myopic patients, not wearing glasses may make the eyes more tired and further cause discomfort. Therefore, wearing glasses for a long time is a necessary and reasonable choice, and will not cause dependence damage to the eyes.

Myth 3: People with low myopia do not need to wear glasses

Myth Analysis

Some people believe that glasses are only needed in cases of high myopia, while low myopia can be ignored. Especially for teenagers with low myopia, many people even recommend that they wear glasses as little as possible or not at all to "exercise" their eyesight.

Scientific explanation

Even for mild myopia, wearing suitable glasses can improve daily vision, especially for students or workers who need to use their eyes for a long time, clear vision can reduce eye fatigue. For teenagers, vision correction is particularly important because blurred vision may lead to incorrect sitting posture, excessive eye fatigue, and even affect learning efficiency. Therefore, even for mild myopia, suitable glasses should be worn according to the advice of ophthalmologists to protect eye health.

Myth 4: Wearing glasses can correct myopia, and vision will return to normal after taking off the glasses

Myth Analysis

Some people mistakenly believe that wearing glasses can "cure" myopia and restore vision to normal, so they expect to achieve the healing effect by wearing glasses. However, the function of glasses is not to cure myopia, but to correct vision.

Scientific explanation

The function of glasses is to provide a clear visual experience by changing the focus of light so that it falls accurately on the retina. It is essentially an "Optical aid" that cannot change the physical structure of the eyeball, so it cannot "cure" myopia. Vision correction is a long-term management process, not a short-term cure. In order to truly slow down the progression of myopia, in addition to wearing suitable glasses, scientific eye management and good eye habits are also required.

Myth 5: No need to wear glasses after myopia surgery, vision will not deteriorate

Myth analysis

Many myopic patients think that their vision will remain clear for a long time and they will never need glasses again after undergoing laser correction surgery. However, maintaining vision after surgery does not mean that it will no longer deteriorate, especially for people who are still in high-intensity eye use, vision may decline again.

Scientific explanation

Laser surgery can correct vision by changing the shape of the cornea, but it does not affect the length of the eye axis or the root cause of myopia. If there is no reasonable eye habit and regular vision management after surgery, vision may still deteriorate. The effect of myopia surgery varies from person to person, and some people may need to wear glasses again after many years. Therefore, even if the operation is successful, you should maintain healthy eye habits and avoid long-term close-up eye use to extend the stability period of postoperative vision.

Myth 6: Children wearing glasses will make myopia develop faster

Myth analysis

Some parents believe that wearing glasses for their children will aggravate myopia, and some parents even hope to "protect" their children's eyes by delaying the wearing of glasses. However, delaying the wearing of glasses not only fails to slow down myopia, but will have a negative impact on children's eye health.

Scientific explanation

Scientific research shows that for children with myopia, wearing suitable glasses as early as possible can improve vision health and quality of life. Children's eyes are in the developmental stage, and blurred vision will make them habitually squint, read close to books, and even cause spinal dysplasia. Therefore, wearing glasses can help correct vision correctly, help children develop good eye habits, and reduce the rapid development of myopia.

How to wear glasses scientifically to protect vision?

Glasses are an effective tool for correcting vision, but they should be worn scientifically to avoid additional visual burden. Here are some suggestions:

Check your vision regularly: It is recommended to have a vision test once a year to keep abreast of your vision and update the lens degree.
Wear the right lenses: Too low or too high lens power will increase eye fatigue and cause visual discomfort. Choosing the right lens power is critical.

Good eye habits: Avoid long-term close-up use of the eyes, especially children, and follow the "20-20-20" rule, that is, look at an object 20 feet (about 6 meters) away for 20 seconds every 20 minutes to relax the eye muscles.

Outdoor activities: Outdoor activities can effectively reduce the occurrence and aggravation of myopia. Studies have shown that at least 1 hour of outdoor activities a day can help children reduce the risk of myopia progression.

As a corrective tool, glasses will not only not damage vision if used correctly, but also help us see the world clearly. By scientifically understanding the real role of wearing glasses, we can avoid misunderstandings and help more people manage their vision health correctly.
