I am certain I need glasses

I am shortsighted now, and my right eye is a lot weaker than my left eye! (I did a test in biology whilst covering nerves and response).

I I have told my parents I need an eye test (haven't been for 6 years), but I don't think they've taken me seriously at all, and I can't get to an opticians (or pay for glasses!) without their support.

I told old them in having some trouble seeing the boards at school, I don't know what else I can say? Both of them need glasses, why don't they take me seriously?
I'm worried they're going to get way worse, and I'm going to end up half blind or something

Why do you need them to get glasses?

Assuming you're under 16 you're entitled to free glasses under NHS legislation

I'm 17, and jobless... Pathetic, I know.

It's not pathetic dude

Are you in full time education, recipient of income support or job seeker's allowance?

Yes, 6th form. Does that entitle me to a discount? The main issue I have is even getting to an opticians really though oh the joys of rural England.

Do you know how I could convince them I need to go?

Yes assuming you're going at it full time then it should be completely free (for a basic set, you may have to pay extra for an "upgraded" frame)
