    You said bad eyesight has nothing to do with eye muscles. Scishow I have various issues with my eyes but one of them is underperforming eye muscles! I can’t see close up or far away without my glasses and part of that is eye muscles. Also because of this the muscles around my eyes overcompensate and try to do the job of eye muscles and fail.

    wait then why does everyone i know (who wears glasses all the time) have to get stronger glasses almost every other year and i (i kinda need them but don't wear them 95% of the time) have the same pair of glasses for 6 years? i got it checked the other day and the optometrist said my 6 year old glasses are the exact prescription my eyes currently need, meaning no degradation over all these years.

    How can someone be both myopic and farsighted? Optically this makes no sense yet people wear bifocals. Also, Wundt's lab test with inverted glasses demonstrated that the eyes (the brain mostly) adjust to different optical input stimulus. By your very own argument, we should be giving newborns glasses to correct for their hyperoic vision at birth. But this is not the current practise! Over time, the eye adjusts its length due to visual input stimulus. So, the idea that "glasses do not affect your vision" is not a myth. It has been shown to be scientifically correct and there are many studies to back this! At one point in the nicotine industry, doctors and movie stars (and feature films... film noir) were used to promote cigarette smoking, but the scientific evidence that showed a direct correlation to various cancers was proven fact. But, who am I to argue with a US $95B eyewear industry?

    Hmm..
    My vision decreased DRAMATICALLY after I got my glasses. Before, my vision was always stable. Slightly blurry, but stable. I went to get my eyes checked and my prescription was so low. Now, my vision decreases so often that my I need New a stronger prescription within months of getting a new one. Why would this be? Yes I am aging, but still a child. Generally a child’s vision won’t decrease so rapidly. I don’t think I believe this.

    Does not correlate with my experience: gave up glasses, got out more frequently to force eyes to focus distant stuff in sunlight. Near-sightedness went away totally. From 7/10 to 10/10 in less than a year, no kidding. So... whatever, that’s my experience.

    I have prescription reading-glasses that I found are of very little help, because I can only see clearly through them if I keep my printed materials or computer screens at a fixed distance from my eyes (i.e., focal length), no more, no less. This makes my wearing them more trouble than they are worth, because I find it very difficult to maintain a fixed distance between my eyes and whatever I'm reading. Eyeglasses only help you if your eyes are able to FOCUS through them. Otherwise, they CAN make your vision worse.

    1:37 I was told that 5 years ago as an adult, and was denied lens that actually let me see clearly, and instead was prescribed glasses that are only very marginally less blurry than my normal eyesight. Jesus, I'd rather have someone from McDonald's that watches the SciShow be my optometrist, than someone who's went to university for years, I guess. I also bought a $700 pair of glasses and rarely ever wore it. Thank you so much, I'll wear my glasses everyday now.

    After about 40 I have started noticing differences with my vision. It`s very crucial to take a good, pure supplement to help keep your eyes and vision healthy. I`ve only started out using this vision improvement method “fetching zuzo com” (Google it) recently. There are signs of improvements to my vision now. It makes me think I should have tried this product way back when my vision was great.

    There is a case where glasses can help cure bad vision, but it’s not related to typical near or far sightedness. In my case, I had a lazy eye, so training the lazy eye with corrective lenses (and some patching) was something that helped me not need glasses by age 13. But that’s a pretty specific case, and I don’t know how it would work if you are trying to cure an adult’s bad vision. Plus, a lot of the time, you can cure the lazy eye, but still have other vision problems unrelated, and still need glasses for those. It’s an issue of consulting an eye doctor, really, someone with the training to know what’s going on with your eyes.

    When I don't have my glasses on, letters don't become blurry, but double or slightly disordered, but if I zoom in enough, I can see them a little better.

    Properly prescribed glasses do allow you to see much better! If you ever go without them, especially if you have a minor prescription, it may feel like they’re making your vision worse. This is only because your brain is missing out on the clarity of vision you have WITH your glasses. Same goes the case for contact lenses.

      You can't possibly know whether it's due to the glasses or not, you never grew up without them. There are plenty of people who grew up without glasses that get bad eye-sight in their 20s, you wouldn't just conclude that their eyes got bad because they never tried glasses...

    When I was a kid, my glasses (they were actually made of glass back then) were as thick as pop bottle bottoms. I was usually the blindest (most myopic) kid in class. Now, specs are plastic and so much thinner and lighter, but as I age I find that I am having problems with my prescriptions being too strong and I need to get weaker glasses. The ophthalmologist tell me I will never have a time where I won't need glasses, but when people get old (I will be 60 in 4 months) their vision will improve some, but not totally. Just enough that the prescription that I am wearing will be just too strong enough to give me headaches and I won't be able to see as well, so I get glasses that are less strong than the ones I was wearing. This has happened 4 times now. My mom had lens implanted when she had her cataracts removed and now needs no glasses. Wish I could get lens implanted like hers and never need glasses again (she wore reading glasses for a couple of years but now doesn't even need them).
