Caught off guard, my son is still myopic! The doctor gave the latest program!


Finally myopia.

During the recent vision examination, my son had completely lost his farsighted reserve. After dilating the pupil, one has not yet had a degree, and one has myopia of 50 degrees.

The doctor said that the "myopia channel" has been opened, and for now, you can consider ordering 0.01% low-concentration atropine eye drops to increase outdoor activities, and use reverse beats to train the child's eye adjustment.

If the power goes up later, you need to wear functional glasses.

In previous articles, I shared functional glasses, and now everyone is more familiar with orthokeratology lenses (also known as OK lenses) and defocusing lenses. OK mirror is worn every night to sleep, you can study and live normally during the day; Defocusing lenses are glasses that must be worn all the time during non-sleep time;

But neither of these are my best choices.

Defocusing lenses are glasses, which not only affect the appearance when worn, but also make it much more inconvenient for the baby to take exercise classes.

Although OK mirrors can be lived normally during the day, they are more cumbersome to remove, wear and wash once a day in the morning and evening.

Just when I was struggling with which to choose, the doctor proposed a relatively new plan, that is, the third choice - defocusing soft lens (it has long been available abroad, and it has just been popularized in China).


Defocusing soft lenses are very similar to adult contact lenses from appearance to wearing, are soft lenses, worn against the cornea, worn during the day, taken off at night, and defocusing soft lenses are thrown daily, do not need to be washed, compared to OK lenses daily cleaning and care is much more convenient.

However, defocusing soft lenses and adult contact lenses are also different, it is not only for beauty, but also to delay myopia function, the functional principle and frame defocus lens is similar, mainly through the lens to do special optical design, to achieve the purpose of normal correction of the center, peripheral defocus.

Of course, the optical design of different brands of defocusing flexible lenses will be slightly different, for example, some brands are progressive multifocal peripheral defocus, and some are concentric circle designs, so the respective intervention effects will be different. Like the American Misight defocusing soft lens, the lens is concentric bifocal design, divided into 2 myopia control areas and 2 correction areas, which is quite exquisite.

Overall, the progress of reducing myopia in earlier generations is about 40%, between the frame mirror and the OK mirror; The several high-profile new products launched in recent years have increased the effect of reducing myopia progression to more than 50%, which is similar to the effect of OK mirrors.

Both can have the invisible beauty of OK lenses, the intervention effect can also be comparable to OK lenses, the care is also simple, defocusing soft lenses can be said to completely cut my pain point, plus I myself wear contact lenses all year round, I have no entanglement with children wearing soft lenses, so this new choice completely matches my appeal!

However, compared with frame optical lenses and OK lenses, there are not many children wearing defocusing soft lenses around at the moment, and the real wearing information that can be learned is really limited, so this time I went to consult Dr. Pan Fei of the Eye Center of Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine to thoroughly ask questions such as the advantages and disadvantages of defocusing soft lenses, which children are suitable, and the risks after long-term wear.

If everyone's baby is at a similar stage to OK's eyes, you can also learn about it together.

What are the advantages and disadvantages of defocusing soft lenses?

For children who are already myopic, there are three mainstream optical intervention options in front of them:

1 - frame defocusing lens

2 - Orthokeratology lens (OK lens)

3 - Defocus soft lens

These three have their own advantages and disadvantages, in fact, after trying to understand their own demands, it is not difficult to choose.


If compared with frame defocusing lenses, then the advantages of defocusing flexible lenses are:

Advantage 1: The defocusing effect is more stable

Although the principle of frame defocusing lens and defocusing soft lens is similar, because the lens of frame lens is far from the eyeball, the defocus effect will be limited by angle to a certain extent, so the defocus conversion is not particularly stable.

The defocusing soft lens is different, it is worn against the cornea, the lens can move with the eyeball, so the optical stimulation of the lens design can be more fully realized, and the defocus effect will be more stable.

Advantage 2: Little interference to children's lives

Just like ordinary contact lenses, defocusing soft lenses are light and comfortable, there is no frame obstruction, it does not affect the child's running and jumping sports at all, and it is a clear field of vision at all times, and the interference with the child's daily life is much less than that of the frame lens.

Advantage 3, beautiful

Needless to say, the defocusing soft lens will hardly be noticed after wearing, and it will not change the child's appearance at all, especially for children who love beauty, this is quite critical.

The disadvantages are:

Disadvantages 1, wearing will be more troublesome

Compared with glasses, soft glasses are obviously more troublesome to wear, especially for children, and they must go through a tossing period at first.

However, from the statistical report, around the first week of wearing, 66% of children can wear glasses independently, and 81% can wear glasses independently after 1 month; If you remove the lens, it only takes one week, and 95% can be completed independently.

Therefore, choosing an off-focus soft mirror, the early stage is still quite a test of parents' patience, and it will save effort after teaching.

Disadvantage 2, expensive price

The mainstream price of defocusing frame lenses is generally about 3000-5000 yuan, and a pair can generally be worn for one to two years;

Defocusing soft lenses are now mostly daily throwing designs, such as Ansigmei, Butterfly Fit, Vision and other old brands, the price of a box of lenses (30 pieces, enough for one month) after the discount is about 600-700 yuan; Cooper's Misight is slightly more expensive, with a box (30 tablets) costing around 850 yuan.

In addition to the cost of the soft lens itself, the doctor will also recommend another pair of frame defocusing lenses, which can be worn one or two days a week, and after removing the lens at night, so that the cornea can relax, and when the child has a cold and fever and low immunity, you also need to change to a frame lens to avoid eye inflammation.

If compared with OK lens (corneal plastic lens), then the advantages of defocusing flexible lens are:

Advantage 1: High comfort

OK lens is a hard lens, it has a "downward" force on the cornea after wearing, so there will be some foreign body sensation, especially in the early stage, it takes a while for the child to adapt;

Defocusing soft lenses, under normal circumstances, are almost no feeling after wearing, much more comfortable than OK lenses. After wearing for a long time, some children's eyes may be a little dry, which is the same as wearing ordinary contact lenses, which can be relieved with artificial tears.

Advantage 2: Simple care

OK mirrors usually need to be worn for a year or two, so there are strict requirements for the daily care process, cleaning, disinfection, preservation, every link can not be slack, which is also the most dissuading me.

Let the child operate it by himself and it is not very reassuring, especially for boys, in case of hygiene problems, it is a new injury to the eyes.

Defocusing soft lenses are not bothered at all because they are thrown daily, as long as they are worn and removed, pay attention to washing their hands, and usually throw away the lenses when they are used up, which is very convenient.

Advantage 3: Clear vision can be maintained all the time during the day

Although in most cases, children can keep their eyes clear all day after removing OK lenses in the morning, there will still be some children who begin to lose naked eye vision in the afternoon due to individual reasons.

Defocusing soft lenses do not have this trouble, can always maintain a clear vision during the wearing of glasses, vision will not fluctuate, even if the glasses are temporarily removed due to some conditions, they can be seamlessly connected with the frame lenses.

Advantage 4: Children with high degree of myopia can also wear it

OK lenses are generally suitable for children with myopia of 100-600 degrees, and the correction effect is not so good; The applicability of defocusing flexible lenses can reach up to about 1000 degrees, and the adaptation degree is higher.

The disadvantages are:

Disadvantages 1, wear it during the day, avoid intense sports and collisions

Although the defocusing soft lens is worn as if it is not worn, if you wear it to participate in intense sports or encounter a collision, the glasses may still have some conditions, so try to avoid these situations when wearing them during the day; The OK lens is completely detached from the lens during the day, so there is no such problem.

Disadvantage 2: Higher requirements for children's eye hygiene during the day

This is actually the same as our adults wearing contact lenses, in addition to wearing glasses and taking off glasses need to wash their hands, when wearing glasses during the day, you should also pay attention to eye hygiene, try to avoid rubbing your eyes with your hands, so for children who love to rub their eyes, defocusing soft lenses are not so suitable.

In summary, the existing three optical intervention methods, if everyone is very entangled in the choice, I think the decision-making path can be like this:

In summary, the existing three optical intervention methods, according to their different requirements, I think it can be selected as follows:

1. If you want to be affordable and convenient, and at the same time not so persistent about beauty and the best intervention effect, you can choose a frame defocusing lens;

2. Pursue aesthetics and better intervention effect, not afraid of trouble, and want to completely get rid of the lens during the day, you can choose OK lenses;

3. The same is the pursuit of aesthetics and better intervention results, but parents do not have much time to help their children care for glasses, and children's eye habits are also better, you can choose defocusing soft lenses.

Which children are defocusing soft lenses suitable for

However, it does not mean that children can control the ability to wear defocusing soft lenses without rubbing their eyes, and defocusing soft lenses still have certain requirements for the child's own physical condition.

1. The degree of myopia is between 100-- -1000, and the astigmatism is below 150 degrees

At present, there is no special astigmatism design for defocusing soft lenses, if the child has a small degree of astigmatism, you can directly dispense the lens without considering astigmatism, and the astigmatism degree is relatively high is not recommended.

2. Be between 8~18 years old

At present, there are also younger children wearing it, so it depends on the doctor's judgment.

3. People without ocular organic lesions and normal systemic immunity

For example, children with keratitis and dry eyes are not suitable for wearing soft lenses. Because OK has allergic conjunctivitis, I also asked the doctor specifically about this, and the answer was: it is okay to wear glasses in a healthy state, if the allergy attacks, you need to stop for a period of time and wait for recovery before wearing.

4. Children and adolescents who are not suitable for wearing OK glasses due to other factors, but have the need to prevent and control myopia

For example, many children choose soft lenses because the corneal curvature is too low or too high to match OK lenses, and choose defocusing soft lenses instead; There are also some children who choose to wear soft lenses because they cannot guarantee more than 8 hours of sleep a day, and the wearing time of OK mirrors is not enough, and trichiasis is also more suitable for defocusing soft lenses.

5. Be able to follow the doctor's advice and review regularly

Needless to say, any kind of optical correction needs to be reviewed regularly and actively follow up the effect.

It should be emphasized that like frame mirrors and OK mirrors, not every child wearing soft mirrors has an effect, but also depends on the personal physique, if the effect is not good, you need to adjust the plan in time.

Short-term and long-term risks of defocusing soft lenses

Solved the problem of glasses, and finally let's look at the risks.

In the short term, it mainly depends on the individual's constitution and adaptation. Just like ordinary contact lenses, some people wear it without feeling at all, and some people wear it for a long time and their eyes will be a little dry, and usually artificial tears can be relieved.

The risk of wearing defocusing soft lenses for a long time can refer to ordinary contact lenses, which are generally very safe.

Under the premise of cleaning and wearing glasses as required, so far, there have been no serious ocular adverse events (including no cases of microbial keratitis) or systemic adverse events.

However, after all, the defocusing soft lens is directly in contact with the cornea, coupled with the requirement to wear it for a long time (more than 10 hours), more or less will have a certain impact on the cornea, so you must pay attention to rest, it is recommended to remove the lens for one or two days a week (remember to wear defocusing frame lenses when you take off the soft lens) to ensure the safety of the cornea.

Well, I want to share about defocusing soft lenses is the above, if you have plans to take your child with glasses, you can also go to the hospital to find a professional doctor for further consultation.

OK, after this inspection, there are still no glasses, and at the moment I can only maintain and improve by increasing outdoor time and practicing more adjustment power

I kept reminding OK every day to look far, and I hated to put a timer speaker in his ear, and I was annoyed when I said too much.

But it's good to be able to wear glasses a day later, my family and OK dad are both myopic, genes are not good, he is estimated to be unable to escape in the future, while he doesn't need to wear glasses now, let him enjoy this free vision more~
