Glasses Prescriptions

I never understood those numbers that opticians give when writing eye prescriptions. So I was reading now on the web what the numbers means. I don't know why I never did this before. Because I didn't understand anyway, I never even made the attempt to note down or remember those numbers, so I don't really know how much the eyes may have changed over the years. We should take responsibility to understand matters relating to our health so that we have an informed understanding. Even my teeth I don't really remember what is going on with them. It is something about being a child and then feeling like it is anyway out of our hands, and if we are not careful we grow up that way. And there is also kind of a disproportionate respect for doctors - probably more especially in working class families like the one I was brought up in. So I inherited that too. So foolish!
