- cbruns 4y agoI only checked your first article, and you're not wrong that axial length change was observed in humans. But it makes the opposite point of what you hope. The myopic eyes only grew longer when subjected to any type of blur. "In addition, in myopes, calculated defocus caused longer eyes (+8.4 ± 9.0 µm, P = 0.001). Strikingly, myopic eyes became also longer with positive defocus (+9.1 ± 11.2 µm, P = 0.02)."
- Aulig 4y agoPlease check out the other articles too or read some more of that article - they point out that their findings are not the norm and speculate as to why that could be. I suspect it's because they used too much defocus (you wouldn't be able to read anything with the amount of defocus they're using, so completely impractical for real life) - that has led to axial elongation in many other studies too.
