The learned men on this forum should explain to the weak people that
come here to ask addvice why:

1) a man goes to the doc and complains about his own imperfect sight
2) doc prescribes glasses
3) man resents the glasses and does not wear them
4) man resents the glasses and he does weat them
5) his imperfect sight either way goes worse
6) in case 3 he is blamed by the doc, in case 4 he is not blamed, just
patted.
7) his imperfect sight remains stable (surely other symptoms are
developing underneath, though)
8) since nobody can tell in advance if case 3 4 or 5 will happen,
please explain why this stuff is called "science".

it is just groping in the dark at the expenses of poor weak people.
