I decided to wear OK glasses in the middle of last year (2025)，At that time, I had been wearing contact lenses for two or three years.。I'm the type whose myopia continues to increase even after adulthood.，Since graduation and working，Basically one year 100 steady rise in degree。
The opportunity came when I took my daughter to see a doctor one day and found that her eyes were bleeding suddenly.，I went to make an appointment for an eye examination.。Although bleeding itself is not a big deal，But by the way, optometry found that my degree has gone up again。Now I have different eyes 675 degree，If you don't control it anymore，Could he really be blind?
So I thought of the OK mirror，In fact, I had heard about it five years ago，I just never thought I could wear it，I asked the doctor at that time，But the doctor said my reading was too high，not suitable。Maybe it’s because technology has been improving over the years.，Now ask the optical shop，Said he could do it。
OK, what is a mirror?
In fact, even people who know OK mirrors now，Most people think that this is for children to correct their eyesight - and it is indeed the case.，Many parents give this to their children。But adults can use it too，The principle is very simple，How many seconds do you press your nails against your skin?，Will it leave any indentation? OK, the mirror is like this，It uses siphonage and eyelid pressure to press the shaping lens tightly against your cornea，Allowing your cornea itself to form a specific shape - essentially flattening it，Because the normal cornea is a convex arc，By pressing it back, a concave lens is relatively realized.。
Because it acts directly on the cornea，In fact, the side effects or complications are similar to those of various myopia surgeries.，Includes ghosting、tailing、astigmatism、Blurry blah blah blah，the good news is，This can be adjusted，And once you stop wearing it，After a few days, the cornea will bounce back.，Safe and assured。
Of course the bad news is：every nightWear them all，Especially those with high degrees，If you forget to wear it overnight, it will immediately bounce back to approximately 200 Degree。Once you resume wearing it, you will gradually return to the
correct，This thing is called in English Ortho-K ，If you tell foreigners, they will have no idea what an OK mirror is 🤣
effect
It is different from ordinary myopia correction。Because the eyeball is spherical，The degree of myopia around your retina is smaller than the center point，Ordinary correction is to add a lens in front of the eyeball，The power of the lens is constant，This causes the image to be the same at all locations on your retina。Then the center point image is clear，The surroundings must be overcorrected，Cause eye fatigue，axial growth of the eye。The OK lens has a defocus ring，The imaging focus around the central point is slightly in front of the retina.，It causes the eye axis to retract (in fact, as adults, we all know it in our hearts)，It's impossible to back off the axis or anything like that.，It’s even difficult to keep the degree the same。But it does effectively slow down the rate of increase)
Of course，There are also some external glasses with similar functions now，Such as "defocus lens"，Frame glasses specially designed to prevent and treat myopia。There are also mobile phones that are now focusing on eye protection.，There will be a defocused screen effect。There are also contact lenses with defocus function, etc.。
price
This aspect varies from store to store.。But from the Internet, there are mainly two types of，One possibility is that it will be cheaper initially，However, you will have to pay separately for each review，including adjustments。Most stores/hospitals may not be able to "adjust" at all，In fact, it is just to change the parameters and then re-customize it from the supplier.。There is another possibility that the price is higher，But all inclusive，All subsequent adjustments and reviews for the one-time payment package。I'm the latter kind，Turns out，I made the right choice (it’s hard to tell here whether I should cry or laugh)，Anyway, time is spent，But I also saved money)。
process
who would have thought，The cornea is fine，On the contrary, my eyelids are different from those of foreigners, so I wasted a lot of time on it.。
2025On July 12th, I completed the examination and confirmed that the corneal thickness was sufficient, and then paid for the order.。they are very confident，The lenses will arrive in two weeks，After learning how to wear it, it officially started。In fact, OK lenses are essentially RGPs (RGPs are also contact lenses，It’s just contact lenses anyway)，The way to take it off and put it on is the same.。If you have any contact lens wearing experience，This is not a problem。
of course，In order not to dry out your cornea，This shaping process usually takes a week or two.，Not just different people，Even the cornea of a person's two eyes will have different softness and hardness.。With shaping every night，You will obviously feel that the degree is decreasing little by little。Of course, during this process, your degree will keep changing.，There is usually free daily disposal provided。
The decrease in degrees is not linear，Because the lens itself cannot be put under too much pressure to damage the cornea，The initial effect is obvious，But in the later stages, it really felt like working slowly and carefully.。Maybe you have already learned from it a few days ago 600 To 200 It's，But that last 50 To 0 It may take a month to see the degree。
Tips
You need a simple way to test your vision at home，At least it can help you figure out how much invisibility you should wear today.。Buying or printing an eye chart is the easiest, most convenient and accurate option。
You should also record the change in your prescription every morning after taking off the glasses.，This way you can tell the doctor during the review，Including changes in myopia degree，The intensity and direction changes of ghosting, etc.。
ghosting
This is what I encountered most during the treatment process，I do have some experience (but not necessarily right)：
- Blurred and fragmentary ghosting：Dry eyes while sleeping，The lens failed to grasp the cornea，So the indentation is rough
- Clear superimposed ghosting：The lens slipped halfway on the cornea，Resulting in two or more flat surfaces being pressed out，You may have fallen asleep
- Trailing like a comet：The trailing part may be unclear or unclear.，The lens does not hold the correct position，Off track，May need to be adjusted，Maybe you're lying on your side
- aperture：Caused by incorrect pressing position，Still off track。For example, the ambient light suddenly becomes brighter, causing the pupils to constrict.，The aperture will become smaller，Because the remote area is also smaller。(But if it’s night time，In fact, it may be that the effect of the defocus ring is not comparable to that of the native eye.)
Keep checking
Normal，Ideally，You should wear OK glasses first、Review in the third week，From now on it will be three months、Half-year review。But obviously I'm unlucky，Otherwise there wouldn’t be this article。My first pair of lenses only pressed 200 There's nothing you can do about it，The doctor found that I have some symptoms of dry eyes，It is speculated that the lack of tears during sleep may cause the lenses to dry up and cause no pressure.，Apply hot compresses and daily artificial tears。of course，I also adjusted the parameters and remade it.。
Second pair of lenses arrives in two weeks，Only to arrive 150 degree，Problems such as ghosting and smearing，It's been another two weeks。During the re-examination, the problem of dry eyes was gone.，But the lens just isn't in the ideal position。Then the doctor takes a vacation，Simply adjust the parameters，Then stop wearing it completely for a month to allow the cornea to rebound.，Prevent old indentations from affecting new lenses。Now another month and two weeks have passed.，Review the lenses three weeks after receiving them。
If you are smart, you must have thought of it，Yes，125 degree。this time，Finally, after ruling out all possibilities,，The doctor found that my eyelids/eyelids are weak... Asians have thicker eyelids，Much fat，Just softer，I can't hold this lens down。Of course it has something to do with the brand，They are a New Zealand manufacturer，Good at complex customization from multiple angles，But the lens material is softer。
Hack
You see, since the eyelids are not strong enough, right?，What if I give him a little more strength? So I thought of using those cheap broken eye masks to help increase the pressure... Hey, don't say that.，The ideal effect was achieved in one night! Of course there are side effects，I just have a double image in the upper left corner of my left eye.，Right eye is on the upper right。The reason is that the lens is pressed tightly by the mechanical pressure of the eyecup.，But it also went astray in the direction of the elastic band.。At this time I can see clearly，But everything has a comet-like tail，As a result, my effective field of view is actually narrower than normal.。And this method cannot last long，Press your eyeballs every night，Very uncomfortable too。
last bet
The doctor was also a little surprised during the re-examination.，The effect is really unimpressive，Of course, it also means that this is not a long-term solution.，The cornea is a very fragile thing after all.。She made an offer to me，I have a difficult and complicated disease.，If it doesn't work, forget it. I'll give you half of the money back and replace it with contact lenses...or we can try one last time.，If it still doesn't work，There is no refund for the money.。
In fact, the feeling of seeing the world with naked eyes is really good...it's hard to extricate yourself.。I struggled for a few seconds and chose to continue.。So another two weeks passed，New lenses arrive，Another three weeks have passed...no difference，still is 150 degree。I started to continue trying the eye mask method，But apparently，After a few weeks it started to stop working.。The lens will become more and more biased with the pressure of the eye mask.，Different eye masks have different effects，Even different sleeping positions have a big impact。
turning point
During a discussion with a doctor，She mentioned that maybe she could try another brand.，Although this brand specializes in low-alcohol content for children，But Asian manufacturers，May better match Asian eyes。Finally I made a loud noise，Asked for a discount，Continue! Continue! Do!
This Asian brand is Menikon，Their alpha，The disadvantage is that it is imported from Japan，It takes more than three weeks to get here，This must be done，One month has passed again。Obviously，Chinese, Japanese, are all Asians，Lenses designed to rely more on tear siphoning rather than eyelid pressure。quickly，My right eye can reach the naked eye 5.0 Got it! The left eye is a little worse，There is double astigmatism。Another three weeks of review and three weeks of slow delivery... finally this morning，After removing the glasses, both eyes reached 5.0! It's finally over!
Left eye struggle
Turns out，After writing this article，The next day I couldn't see clearly with my left eye again.。Then I kept going back and forth and still couldn't keep up with the effect of my right eye.。Finally use elimination method，I've found that it's quite possible that in some cases I，Your eyes may be slightly open when sleeping，Caused dryness of left eye。Now I take an extra drop of Hylo artificial tears before bed，Now，Finally both eyes are stable 0 Myopia and astigmatism。
For now, just keep wearing it to ensure the effect is stable.，grow over time，The indentations are becoming relatively more fixed.。The effect will be better。
Summarize
This is truly a "march of suffering"，From July last year to May this year，I went out on and off for more than half a year.。The doctor even used my case as a classic case to write a textbook.。
The most painful part of the whole process is probably having to sleep on your back every day.，In fact, now that I have changed my lenses, I have found that as long as they don’t put pressure on my eyes,，It’s okay to lie down on your side.。
Thanks to the two brothers Grok and Gemini for encouraging me during this period and later for praising me as a placenta。I also thank them for the countless bad ideas they came up with.。
But Grok was right about one thing.，It turns out that when I got my second pair of lenses, it recommended me to change brands based on literature analysis.，Such as Menikon。But since it cost extra to change the brand, I didn’t change it.，Otherwise, this process should be shortened to less than half a year.。
(pity，Now the free version of Grok is almost out of use，The paid version is really unaffordable...)
