The fact that millions of schoolchildren require vision remedies on a daily basis so they can more readily assimilate into the culture of public schooling does not mean that these children are damaged. It means something is very wrong with the whole idea of shooling!
Some are better at seeing things up close, some see things better afar, but that does not mean that anybody can feel at liberty to try to remedy their vision with unnatural appendages to their faces.
My perspective is one of a parent of an elementary school aged child. There is now an inordinate amount of time spent sitting and testing of these children and it seems to worsen every year. The high stakes tests are now tied to teacher performance and most importantly their pay raises. This has led to rampant (mis)diagnosis of nearsightedness and farsightedness of very young children by people that are far from qualified in making this call. My child was “diagnosed” by a new principal after a five minute classroom observation. The classroom had a substitute teacher that day and the child was squinting and grimacing. The principal called me at home to tell me the child needs to be remedied in order to perform well in school.
