> if you do a lot of near-work it can think you are still hyperopic, causing further myopia progression.

Does this mean we should let our eyes see blurred images so our eyes would feel like they are seeing far away stuff and stop axial eye growth to stop myopia. This is in direct contrast to the claim in the post

> a few minutes a day with glasses or contact lenses that correct for blur stops the progression of myopia

which believes corrective lenses that correct for blur would stop the progression of myopia.

Note the references to color in the 2022 Nature paper:

> Here we show that, even though filtered movies looked similar, eyes became significantly shorter when the movie was sharp in the red plane but became longer when it was presented sharp in the blue plane. Strikingly, the eyes of young subjects who were already myopic did not respond at all—showing that their retina could no longer decode the sign of defocus based on LCA. Our findings resolve a long-standing question as to how the human retina detects the sign of defocus. It also suggests a new non-invasive strategy to inhibit early myopia development: keeping the red image plane on a computer screen sharp but low pass filtering the blue.

  • Okay that's great, except children get their myopia before they become casual laptop users.

    I wonder if doing the same to TVs and tablets will do anything.

    • From the Show HN submission above:

      > Some myopia control techniques work similarly, like MiSight and Hoya lenses.

      MiSight is a contact lens used to slow myopia progression in children, aged 8-12 at the initiation of treatment.
