    The normal dynamic eye moved negative because of long term close work, and because of the minus lens used to fix the first self induced problem.

    I became slightly myopic when I was 11, I refused to wear glasses and my myopia practically didnt progress for many years, got contact lenses during university, and then my vision started really go down, to -5 when it finally stopped when I was ca 25.

      Very mild prescriptions such as -0.5 can fluctuate towards zero over time. If it was a -5.00, that's another story!

      I have found that, at 20/60, I can wear a plus 2 lens, for all my close work.
      Then slowly, my Snellen clears to 20/40.
      Passes FAA PRIVATE Pilot license.
      Then, more plus, and slowly the 20/20 line is clear.
      This is a refractive change of from -1 Diopters, to +0.5 Diopters.
      The process is comfortable for me.

    Why does the brain elongate the eye when the focus is already on the retina (before elongation in the video)? I don't understand that. Shouldn't the vision already be clear because the focal point from the light is already on the retina?

    • @lumenoptometric
      @lumenoptometric  Před 3 lety +6

      Hey there, here is a summary of many studies over the past decade testing traditional single vision lenses (what most kids wear) versus other corrective methods thought to slow myopia. In terms of experimental design, single vision lenses are always the "control" because it's a universally-accepted fact amongst researchers/practitioners that normal single-vision glasses worsen eyes.
      www.ncbi.nlm.nih.gov/pmc/articles/PMC3624048/
      For more of a fun study, this one actually used lenses to purposefully cause monkey eyes to grow asymmetrically. This one's a little difficult to parse, but what they did was insert lenses into monkey's eyes where half of the lens had myopic correction and the other half didn't. Half of the eye that "saw" through the myopic lens grew longer, whereas the other half didn't. Dr. Earl Smith's research was the first time researchers were able to manipulate at-will the eye's length with lenses.
      Hopefully this helps.

      ​@@strong1134 Hello Strong,
      This topic is a little bit more complicated and we only tried to scratch the surface with this video (we simplified some of the terms for simplicity as well).
      Unfortunately we can't optically engineer our eyes to reverse the axial growth. Doctors have documented it from time to time, but there are no large-scale, mass reviewed studies. We aim to slow or significantly stop the progression, but I'm not aware of anyone promising to reverse it.
      Myopia, under most conditions, is inherited.
      To better understand these concepts, you may inquire to see if any local eye doctors hold any seminars regarding myopia progression. Again, do remember that some of the terms of the video are an oversimplification of optical correction, so other doctors may choose to explain it in a slightly different way.

    Is it possible for a 28 year old to have myopia now? I'm 28 years old and I've already had tests and had perfect vision, but after the quarantine my vision got bad at night and the ophthalmologist says I have myopia -1.25. I started wearing glasses and today it has increased to -1.75. Is this possible, because I thought myopia was a thing for teenagers?

      It can happen, just more often starting around 8-10 rather than in your late 20s! Some patients are late bloomers.
      But realistically spending more time outdoors and less time on the screens might help to reduce some elements of "transient" myopia.

      If you need glasses, it is always important to wear them, especially if safety is a concern (such as driving). Not wearing glasses and seeing blurry can also worsen your vision as a child/teen. Even though it sounds like a lose-lose situation, there are ways around it with special types of lenses.

      Ortho-k might be what you're looking for. Some caveats exist, though. There are no studies involving slowing myopia for adults, but optically the effect is the same as for kids. Theoretically if adult eyes elongate for the same reasons as children's eyes, a treatment method such as orthokeratology would be something worth looking into.
