    "The only effect they may have on your eye muscles is reducing excessive strain on them" If you are myopic your eyes suffer from OVERLY EXCESSIVE EYE STRAIN - glasses expand the rays of light causing the image to appear closer to the eye the closer an object to your eyes the more strain they are put through to let you see a crisp image so wearing - glasses WILL cause eye strain and will worsen your eyesight if you are using them from close

    Ok fine if you're born with poor eyesight. But what about those of us with perfect vision that goes south as we age? That's a whole different story and specifically has to do with stiffening lens muscles. Have studies been done on these folks to determine the efficacy of eye glasses over time? I'd love to know the answer to this as it directly affects me. TY in advance. :). 🤓

  • h baker

    Hank, why is my vision so bad? Every year for 55 yrs since I was in the third grade ( you do the math) they have gotten more and more near sighted where I have had to change Rx yearly and can only see clearly about 6 inches in front of me now. I wear trifocals. If I misplace my glasses I have to have a 2nd pair stored in a specific place in the house at all times for emergency back up to find them.! some say to wear them less to force my eyes to adjust back little by little, like wearing orthodontic braces to realign teeth. Any truth to the myth? can you improve your vision by doing less close work like reading and computers?

  • Allison Jacobsen

    I needed to get glasses in the 9th grade. From about 6th through 8th the world was pretty blurry past about 6ft. Once i got glasses i was able to see things i had no clue existed personally...like stars and leaves and grains of gravel on the paths... After a few months i got used to the glasses and when i take them off i can only see about 3 ft, and everything past 12 now is completely blurred. So glasses are better, but once you get used to them its hard to cope without them.

  • Travis Johnson

    I was told I needed glasses when I was young, got some, wore them for less than 1 day, and decided against them. 15+ years later, I get by just fine without them. Obviously, my vision is not perfect, but much better without glasses than lots of people my age who grew up wearing them. So I'm glad I never did; I would have been reliant on them, unable to get by without them.

    I got prescription glasses in fourth grade and HATED them. Later I figured that I just got a bad prescription and got new glasses. I disliked these even more. I went back to the first prescription. Now, I barely wear my glasses (I'm not able to drive yet) but my prescription luckily hasn't changed in five years. I can't quite explain what I hate so much about them, but it's related to color and it's driving me crazy trying to figure it out. Anyone else have a similar issue?

The more I used my glasses the worse my vision gotThe same is for my brother and he needs his third pair of glasses that are A SSSHHHIIITTTT TON stronger than his first pair

      Interesting theoretical scenario. Is this based on any serious academic/peer-reviewed studies - or are you just using your imagination and presenting unproven hypothetical situations and self-serving speculation?

      No disrespect intended, but where's any evidence to back up your colourful musings and opinions? You know - facts.


    • Daniel Daniel
      Daniel Daniel 5 days ago

      I will try to give you a short explaination- let's take minus glasses for example because you have written a study about myopia- minus glasses always create an image between the lenses themselves and the focal
      point of the glasses when you look through the glasses you see the image and not the object himself so if lets say you wear a -4 glasses its like staring at a screen constantly from 25 cm away from your eyes which put huge strain on your muscles, but thats when you look at something far away if you read using your distance glasses the strain will be even bigger and will cause a progressive myopia
      why have you study showed those results? your eye condition is based on your life style and how much you look at things from close range and long range if I will compare the eyesight of 10 gamers and 10 athletes who do you think that are most likely to have myopia?


    • TheStockwell
      TheStockwell 5 days ago

      From the BBC website: "There’s no suggestion that wearing the correct glasses will make (. . .) eyesight worse than not wearing them at all. In fact the longest-ever study of the progression of myopia, which has just published its 23-year findings suggests the contrary. Back in 1983 a group of children in Finland with myopia were randomised to various conditions, including reading without spectacles. Their myopia progressed a little faster than those who wore their glasses continuously. After the initial three years of the study, they were all advised to wear glasses all the time. Twenty years on, there was no difference between the groups."

      That's a bit less subjective than saying, "My Uncle Bernie put on glasses - and was blind in a week!" Eek! :)

    In my experience, after studying hard for exams in bright light, I got a severe case of myopia this frightened the hell out of me because I did not want to wear glasses because none in my family wears one and to me, its like becoming handicapped as you become permanently dependent on something.
    after some research and focusing on far away objects more and squinting full Asian when in bright light or studying, after about 2 weeks I am back to normal
    i still get myopic when dealing with close work however looking outside the window at the sky and far away trees seems to correct it pretty well

    So you say it's NOT the muscles that make the eyesight poor, but the eyeball shape, or WHERE in the eye the focus happens. Then you say diopters worsen because of wekened ability to focus on different things (what the muscles do), when actually diopters are supposed to be determined by where in the eye the focus happens.

    So you say muscles don't matter, then you say they do matter.

    I say they do matter, they're just not the only aspect. Hence why so many people have experienced worsen eyesight right after glasses and why so many people have fully cured their eye sight by exersize, yet simultaneously a lot of people can't do that.

    There are many factors to eye health. I believe the industry wants you to dismiss a whole bunch (like eye exercise and nutrition) and go straight for glasses, then another pair, then another pair... When in reality a lot of people could benefit and some even cure their problem entirely giving those attention.

  • CodeKujo

    When I was young, my eyesight was around 20/15. Then around 12 years old, my vision started to degrade. My prescription was getting stronger such that I was getting new glasses every year. Each time, I would get glasses that restored my 20/15 vision. Then one year when I was getting new glasses, the guy stopped at 20/20. "I can usually see better than this", I said. "Well, I could keep going, but since you do mostly computer work, it's just going to give you eye strain as your eyes have to work more to focus up close."

    I left that day with two pairs of glasses. A distance pair for driving and sports, and a pair that corrected me to 20/50 for computer work. My prescription has been stable since then. I was 26.

    The role the eye strain played in my changing prescription is unclear from just my experience, but the eye strain is real. If I forget my computer glasses and try to do a full work day using my distance glasses, it's very uncomfortable after about four hours. I suspect there are a lot of near-sighted people who would be a lot more comfortable wearing a weaker prescription at work.

    Not true. I wear glasses only in exceptional circumstances (driving) and that's why I have same minus(-1) for 13 years+. Basically people who wears glasses or lenses lost more sight. Eyes exercises also help .I work on computers for all my life and if I wear glasses all this time, I bet my vision would be way worse. I don'y it's cool to wear glasses or lenses, because they are not good for a fight, if you are a man.

    Jeanette Hansen 2 months ago

    *Coughcough* The idea of glasses making your eyesight bad is because of how the chinese handle failing sight (with age). They proscribe paliptating the orbital muscles to try and strengthen the bloodflow to the eye and thus the ability to focus the eye properly. It reportedly works in many cases, but worth investigation.
    (Choosing one solution over the other seems to be a cultural thing. )
    Thinking that glasses will purposefully make your eyesight bad.. nyeeeeh. That's backwards..ish.
    Either way, glasses or exercises, may you always see clearly! ;-)

  • Neil Doerdan
    Neil Doerdan 2 months ago

    They missed the research that revealed that although glasses do not ruin your eyesight, they certainly can make it worse. The only way to make it better is to stop or reduce the activities that cause the damage in the first place. Too much close up work for too long a period of time in poor lighting conditions.
    Myopia can be repaired by allowing the ciliary muscle in the eye time to relax and return to its normal size along with retraining the eye to regain focus over long distances. If you wear glasses/lenses for close up work you add to the damage that can be done. If you wear glasses/lenses that give you 20/10 or 20/20 vision, then your eye thinks it is good and doesn't need to resize to get back to focus.

    • Neil Doerdan

      Jormungand13324 relied to that video as well as they avoided covering any of the research into glasses causing the axial length in the eye to increase, which not only leads to higher myopia but may eventually lead to retinal detachment as the eye elongates. Take a look at Jake Steiner for examples of research used.

    • Neil Doerdan
      Neil Doerdan 2 months ago

      The research they referred to at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4087177/ would only use patients who were full time spectacle wearers (and I would assume the same pair of spectacles that corrected the myopia). As such this is what causes what is called lens induced myopia. If you are less than 2 diopter you should never wear your full prescription glasses for close up work, if you wear contact lenses then you can get around it by using reading glasses for close up work to avoid over straining the eye muscles.
      To correct vision from 5 diopter back to 20/20 has been done in less than 3 years. But for many people, 3 years is far too long a time, so easier to continue to wear the glasses for the rest of your life...

    having or short sighted getting worse every year

    Those who didnt wear their glasses, or just wear them occasionally, after a few year they no need glasses anymore!

    the real life case is very clear
    and whats even clearer my eyeball size has change since i wear glasses, so does i notice those who wore glasses in my family. These things are so obvious why researcher didn't notice it ?

    I have a severe myopic, and i regret i wore glasses all the time ( starting from age 7 i have perfect vision, 8, 9 years old i have 200 degree, than it just keep on increasing a lot every year )

    Fantastically stupid. Glasses definitely have made my vision worse. You described how eyes work, but failed to address why eyes become more oblong, and jumped to conclusions without evidence. This may be anecdotal, but i have experimented with my own vision and roughly measured changes by measuring the distance from my face where vision can focus - i got definite improvements after periods of not wearing glasses. I wish i could do.it more often, but unfortunately i have to live and work, and need the glasses too much. So people, don't listen to this trash… if you feel fine or 'good enough' without glasses, dont start the dependency. This channel isn't worth my sub anymore.

    bruh when I was a kid my vision was perfect then puberty hits.. and although it did lots of great things, one thing it did was made my vision shit. I can't see in the distance for the life of me lol

      I'm not too sure.. that was all my doctors told me, it's a common thing for eyesight to worsen or improve during puberty for whatever reason it is. I have glasses, I jus't don't really wear them.

      This may sound dumb to you, but your eyes don't elongate because of puberty, but rather the improper use of focal planes. I'm a teenager and my vision is improving. My eyes are shortening, due to the use of focal planes and stimulus. You're not a genetic failure.

      that's what both my doctor and eye doctor said. Vision can and most of the time change during puberty years. It is a myth that eyeballs are fully grown at birth which, they are not. Often times through puberty eyes will grow, or as this video might put it, "lengthen". Besides, both my parents got shit eyesight too lol

    The truth is... overcorrection ruins your eyesight. Including doing near work with a lens strength appropriate for driving. Glasses, if you already have mid to high myopia, prevent your sight from getting worse. But at -1 or less? If only you avoided them to begin with and made positive lifestyle and health changes, you wouldn't be at -6 with risk of retinal detachment now...

    This video tows the line of mainstream optometry. I wouldn't really expect anything else from it. But it is an utter tragedy that we all are being played for money like we are. We are being lied to. Luxottica is a monopoly! They have far too much invested in this lie to let little ol' Hank dismantle their industry!

    Urgh my first ophthalmologist gave me glasses with a lower prescription when I first started wearing them, thankfully changed doctors soon and got the correct prescription, albeit after like a year or so. Also, I had astigmatism so don't know if that's why my eyes got worse and worse or because of the wrong prescription or both!!!

      Full prescription = prescription that is supposed to give you 20/20 vision (often overprescribed). When you're doing a close-up activity (eg looking at your phone), some of the light goes past your retina. Your eyes, wanting to remain in homeostasis, elongate, and as a result the light is focused further inf ront if your retina.

      LilMsMalevolent Your eyes got worse since you wore that full prescription while you were doing close up

    That's messed up. Thinking that you are more likely to be a nerd because you wear glasses.
    I have perfect 20/20 (although I can already tell age is affecting my vision) and always have had perfect vision.
    I can probably out-nerd a number of people here in these comments...
    I have a feeling there's absolutely no correlation between eyesight and smarts...
