How blind are you?

[Dymetrie]

So I went to the opticians yesterday for an eye test.

Very thorough lad who checked my vision, reckoned I had very healthy eyes and told me they were slightly worse than the prescription on my current specs (which are about 5.5 years old).

So I checked out the numbers he was writing down and his expert evaluation was that my right eye was -4.25 and my left was -5.25.

Is that bad?

I mean, I know that I'm pretty much blind without my cybernetic implants connected (even need them to read a book and can't see what's on my PC screen(s) without them)...

Anyhoo, how blind is everyone else? Can I be trumped because them figures look pretty high (or low)...
