Hiya mate and welcome! Good to have another guy on board!
There's loads of valuable info on the site. If you cant find something your wondering about and cant see it in the most recent posts try the 'Search' function in the green bar above, or the stickys section, failing that feel free to ask.
You're not alone. You get your eyesight test and there's 3 possibilities VA1 VA2 VA3 and Worse than VA3. You have to come within VA1 and VA3 to pass. My eyesight is -2.00 each eye and I passed with VA3 uncorrected and better than VA1 corrected.
