VTI investment case, page-7

I remember a few years ago my ophthalmologist said my myopia progression would be reduced by wearing contacts (the ordinary kind) but wearing the things was a major nuisance and hassle in several ways so I stuck with glasses. The tech interests me and VTI is on my short/watch list but I can’t help but wonder what the uptake will be for contacts among the largest target demographic or even the whole target market. Anyone aware of research on this? Thanks.
