| Anecdote, as a teen, I was diagnosed as having myopia (mostly on
| one eye) and got glasses. I refused to wear them most of the
| time, during that time I spent more time outdoor, looking further
| away and also develop an habit to stare at points far away
| whenever I'm thinking.
|
| Since I'm 25, whenever I do an eye test, they tell me that I have
| a very small amount of myopia on one eye but it's very small and
| I don't need glasses.
|
| Interestingly, when I talked to an eye doctor recently, he told
| me that they no longer try to push glasses so much when there's a
| small vision issue.

| Another no-glasses technique I've heard works is Orthokeratology,
| specially shaped contacts that you wear at night which reshape
| the lens, and the effects last through the next day. I find
| contacts incredibly uncomfortable to wear during the day, largely
| because it's very dry where I live, but I suspect I could wear
| them comfortably at night.
|
| Ortho-K is fairly expensive ($1-3K from memory), and fairly rare.
| I could only find a couple places that do it in my entire state.
| hondadriver wrote:
| I use those (DreamLite)and they are getting more and more

| sells them. They around EUR 500 a year including cleaning
| fluids and check-ups.
|
| Be sure to get checks regularly and practice extra good eye
| hygiene, because they do have a higher risk of infections, also
| eye doctors do not recommend them.
|
| Biggest drawback I experience are coronas around bright lights
| at night, but you do get used to them. I can conformably drive
| a car at night, because the sight is sharp. The extend also
| varies from person to person.
|
| If you can tolerate the lenses with your eyes open, you can
| also already wear them in the evening if you need perfect sight
| in low light.
|
| On topic: you cannot permanently reverse myopia, but it gets
| better when you get older for some people.
|
| Ortho-K lenses can however be used by children to stop myopia
| from getting worse.

| eyes won't be fixed, you would just get better quality vision
| through some other way doing this?

| Well... my eyes have gotten progressively worse (more myopic)
| since I started wearing glasses regularly to work about 5 years
| ago. This was in my early 30s. Before that I didn't wear glasses
| most of the time, but I still had some myopia that could be
| irritating at times. I could still, eg. drive comfortably without
| glasses. I can no longer do that.
|
| It's something that has felt wrong to me, and worried me a lot
| (you know, since I use my eyes for a lot of things that are
| important to me). I will definitely look further into this and
| try the techniques discussed here.

| Perhaps I misunderstood Slide 16:
|
| Myopia progresses in two stages: (1) near work induces lens
| spasm, causing pseudo-myopia; (2) use of minus lenses
| temporarily improves distance vision, but leads to eye
| elongation and axial myopia. The result of elongation is a
| need to prescribe stronger minus lenses, in a vicious cycle
| of ever stronger lenses.
|
| I haven't watched the video yet, but this sounds like my
| experience.

| Yeah, it's possibly true but I guess I'm just skeptical

| easy to confuse the symptoms (eye elongation and axial
| myopia) as being caused by the glasses rather than just by
| whatever factors originally caused the myopia (or if it was
| genetic/age driven).
|
| From a brief search it seems that studies show that glasses
| don't make eyesight worse.

| Does anyone have actual experience reversing myopia? During the

| for the first time ever (presumably the worsening was already
| there but accelerated by being on my computer more during
| lockdown, working longer hours, getting out of the house less).
|
| My prescription is really slight (I think like -.5 or -.75) and I
| was really curious if this was reversible at all, but I'm
| skeptical of claims that it is.

| to having a great vision I can't complain about.

| Reasonable points.
|
| I'm also very skeptical when doctors say you have to constantly
| wear glasses. It's more logical that with glasses our eyes are
| becoming even more lazy.
|
| All this myopia pandemic looks like a natural consequence of our
| modern lifestyle - looking at screens most of the time. So it's
| more like an adaptation. But I don't think it's possible to
| reverse it without throwing away all the screens.

| thinking of the kind (where we "look inwards" mentally too much,
| focusing on our faults or trying to figure out what's wrong with
| us or the world) over a period of time, contributes to some form
