I do not remember the first time I got lenses (age 5), nor much at all before that age. I do vaguely remember visits to the eye doctor once or twice a year throughout my childhood. I was very nervous and anxious, aware that I was "failing" to see well, in a high state of stress the entire time. I'm sure that among those born after 1960 there are also a few people with that very high level of anxiety (and therefore high level of myopia), neonatal drugs or not. Not to dispute your theory, just to point out that I don't think it was a key factor in my own case.
