Distribution of diopters?

Hi all,

I was wondering if any studies have been done showing the distribution of different diopter prescriptions across the population? I'm hoping to find a bell curve of some sort.

The closest I've found are either general studies showing how peoples' vision changes with age, or are split into high/low prescriptions only (e.g. above and below -5.0/-6.0 for myopia) without any further detail.

Does anyone have any info about this? Thanks in advance!
