On: Reversing Lens-Induced Myopia (2018)

[argonaut]

A randomized controlled trial in children found that undercorrection accelerated the progression of myopia. https://pubmed.ncbi.nlm.nih.gov/12445849/.

This trial had a similar but not statistically significant result: https://pubmed.ncbi.nlm.nih.gov/16907670/

(There are conflicting observational studies, but these two were controlled trials).
