Is this a rigorous study with control group and large selection?

Otherwise it looks like an option not considered seriously. I'm not going to medicate daily for the rest of my life to "decrease or slow by about a half". The promised result is wimpy - you still need to wear the same glasses till the end of your life, but hey, they have different numbers.

I am 50 years old and -14.5 diopters in both eyes. Slowing by half would have been a great outcome by comparison.

This is an article summarizing multiple experimental studies.

You wouldn't medicate for the rest of your life, just until adolescence, when eye growth slows down.

The promised result is far fewer high myopes, which means fewer retinal detachments and other risks of high myopia.
