I might be misreading what you are saying but it still sounds like exactly the opposite? (As in, that exposure to blue light is linked with myopia, not that blocking blue light is linked with myopia.) FWIW, I assume I am simply misunderstanding your use of "linked to" (which I thought is only ever used to establish a correlation, not an anti-correlation; like, "new study shows red meat linked to hear disease" would be awkward wording if one meant "prevents").

You are misreading what was said. Its not either, or. There are two things mentioned in the context of light mediated pathways, thus two bounds, one from the lower frequency going down, and one on the upper frequency of the visual spectra going up. The papers from the author's mentioned, specifically Hollwich, showed that when the light pathways are blocked as happened in coma patients, and eye surgeries at the time, it showed up problematically (in outcomes) and in the biochemical tests they had done in those patients, and rapidly corrected once they were exposed to natural light. Incidentally, these studies lay a strong groundwork for a causal link with the underlying biochemistry and light in people, not just correlation. They controlled for this rigorously, comparing bloodwork for other surgeries, and similar in naturally blind people including those that lacked or didn't have normal photoreceptors. Overall it was consistent in support of light mediated pathways within the eye itself. The depressed biochemical activity in some cases was so severe over such a length of time that it led to physical deformation of the eye which is common in myopia/macular degeneration/retinopothy, which resolved itself upon sufficient exposure to natural light in most cases. There are two loops that are impacted dramatically by light which ramp up or slow down activity in the pituitary. Retinopothy is closely associated with spikes of high energy light waves in the Blue-Violet spectrum (phototoxicity). Macular degeneration, and Myopia with lack of Red-NIR-IR light. Hopefully that clarifies. The papers involved were groundbreaking, and hardly anyone outside of the field of Ophthalmology have heard of these people, there are a lot of people that seek to draw fallacy and discredit because lack of evidence. There is a vested industry that would be impacted as a health hazard (all LED displays). Very little research has been done on these pathways because there hasn't been funding, similar in scope to the same way flouride research in water was done, which took India doing a comprehensive national study to show it lowered IQ in children above a certain threshold in ppm; nonetheless the fact that these pathways do exist is not disputed. There is solid science to support it.
