Tried with the mother of a 11-year-old boy who got his first prescription last year. About -0.75D.
I didn’t mention EM, or a bearded guru, etc.
The colleague has mid-myopia, and the whole family is between -3.5D and -8D. So she bought into “it’s genetic” but was also worried where in the scale the son would end up and how much it would turn him towards more indoor hobbies. I simply mentioned that my once -2D just got measured as no glasses needed by an opto (opto = credibitility). And I added that the usual thing with kids is to have them wear glasses for everything except for running around (in fear of breaking the expensive glasses), while my mum’s method (white lie) was the opposite: to wear them for distance only (when I really noticed the difference in vision with and without glasses) and not for close-up where I could manage clear vision any time without any eyestrain easily. Then to convince her further I added that after all glasses were prescribed because I and her son failed at a vision test at black/whiteboard distance, not when reading a book.
She said that made sense and confirmed that at this stage her son simply forgets to put the glasses on for school work or at home and doesn’t like wearing them in general either. So I advised to only have him wear them when he asks for them, e.g. watching TV - big screen, good distance.
This one was a win.
My neighbour is around -10D, we chatted about other things and then she mentioned her headache with her new glasses but wanted to wear those as those finally gave her enough clarity for driving (she is fearful that if her myopia progresses then she won’t be able to drive after a while). So I advised her to find old glasses from 2 years ago and wear those for arm’s distance - she cooks a lot. And to wear the glasses from last year at home in general. That was the max I could achieve (as she thought ordering glasses online from China is “dodgy” - well, just as dodgy as the opto’s glasses are…). She was very happy about these changes a few months later as this reduced her headaches. She accepted that wearing lower prescriptions at home was more comfortable because distances were shorter within the flat. But she would not consider reducing 0.25Ds from the glasses…
Mentioning EM, internet, guru, etc challenges biases and is an invite not to trust in medical professionals. These cause discomfort. You have to meet them where they are. Or just hint on what’s possible and meet them in 2 years’ time when they have at least 0.5D more added after 2 more visits to optos and the seeds of doubt have grown a bit driving them back to you… (and by that time you’ll have 2D less in your correction => even more convincing it is possible)
