I remember when I was young at school, the teacher asking me (Along with others in the class) if I had been to the optometrist.

When I asked why? I was told not to be stupid that everyone needs their eyes tested and that she would speak to my parents...??

So mum took me to get my eyes tested and I could read near to the bottom of the chart. They then stuck me on some huge machine thing (this was 20 years ago), basically spun around these different lens.

I remember asking what it was? and the guy was like its to work out what glasses you need.

When I said why? I just read everything on your chart. He said because I could still benefit as one of my eyes wasn't quite as strong (I struggled to read the bottom line fine print with my left eye).

I told my mum I didn't want glasses did a big turn and we left...basically threw a fit (which isn't something I did often).

30 years later and I think it's time for me to go again, as after a couple hours of reading it blurs a bit.

Not sure where my story is going...oh, only that, I think while our 'global medical systems' are good and based on good tested science, sometimes the capitalist world gets in the way of logic.
For instance why use a baidaid (glasses) to sew a cut; I think finding a natural way to help should be the first port of call. I hope it keeps working for you.
