Couldn't read it all as it was a bit of a mess
One point I wanted to address. Having worked in a large high street opticians, a wearer of glasses and friends with optoms I'm pretty sure that the optometrists had/have little input into the decision to buy glasses beyond simply stating the results of the exam. They would generally merely test their eyes and give them a perscription - if it was a mild - or + *they would say it's up to you. Even the people on the shop floor NEVER had any pressure to sell to people who didn't need them. Are you actually accusing optometrists of going against their duty of care and forcing glasses onto those who don't need them? *I know several people who have been for eye tests to be told they don't need glasses - despite them even thinking they did - so why wouldn't in this case the optometrist take advantage of the situation and recommend glasses?
As for the other points they're a bit first world problemy - working on weekends and bank holidays, £27k starter salary. Behave, it's a bloody good job compared to what a lot of graduates are on. Don't like it? Train in another field.*
