Timeless wisdoms
People say dumb things with a lot of confidence. Ten years later they realize how dumb they were.
I can say with confidence that many of the things I say with confidence today will sound dumb in 10 years
^ Will saying that be dumb? Probably not! That means it’s a good one
At least the change from confidently saying things to them becoming dumb is growth in wisdom

Red light therapy for axial length reduction
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10011348/
Our research highlights RLRL as a promising and novel therapy that can shorten myopic AL in more than 25% of eyes by 0.142 ± 0.095 mm/year.
Need to look into the device used. My theory and hope is they were getting myopic peripheral defocus. Also need to look at the study that shows peripheral hyperopia is the strongest correlation to axial length increases, because that had some references to cons/rods and what type of light is most impactful.
Their website (https://www.eyerisinginternational.com/the-device/, just choose new zealand or UK) says the red light is targeted on the retina. See also their blog post: https://www.opticianonline.net/content/features/myopia-repeated-low-level-red-light-therapy
I also wonder – there’s WTR (with the rule) astigmatism. Could that have anything to do with the fact that most lens wear is wider than tall? Or maybe it’s just Elliot Forrest’s ideas about posture

Idea:
If it is really the case that axial length is most responsive to peripheral stimuli, then wear diffs outside with the center blacked out. The diffs should be weak enough that there is defocus at the peripheral area.
Maybe that just makes active focus easier, because you won’t be trying to focus consciously anymore.

East asia actually has made some progress towards solving the myopia problem.
Miyosmart – research seems to only indicate slower progression. Seems like they their test subjects didn’t have consistent usage, and they didn’t have a standard around how much myopia defocus to create peripherally.
Kubota Glass – operates the same way as miyosmart but with AR. Focuses on lens induced myopia, specifically the peripheral hyperopia.
There was a quote in the Kubota paper about peripheral hyoperia, which makes me think to reduce lens-induced myopia, one should wear lenses that limit the amount of peripheral hyoperia. EndMyopia method of course uses reduced prescriptions, but on top of that maybe it makes sense to wear smaller lenses.
My guess would be it doesn’t make that much of a difference. Then again going from a 35mm lens to a 30mm lens would be roughly 25% less corrected light.
It has been shown that peripheral hyperopic defocus on the retina is the chief driver of axial elongation of the eye11,12,13,

- For differentials, do not use high index lenses. They introduced way too much chromatic aberation. Hi-index plastic (zenni 1.67) has Abbe of 32 vs Plastic CR-39 (zenni 1.5) has Abbe of 58, higher is better. In this case, 1.5 is significantly better. I noticed this when looking at the youtube favicon or iOS notification count badges, where in different parts of the lens, the center part of the icon would move around in the red. Very annoying actually
- Cooper vision (COO) owns a lot of the myopia reversal & progression reduction tech like MiSight contacts. I sold off a while back but it might be worth rebuying. At least until I put them out of business
