Yes, really. Get your eyes tested if you don't already were specs. I though my vision was fine. I could read road signs well in advance and also looking at newspaper print didn't hurt my eyes. The, in a silly, boozy moment, I tried on my mates glasses [as you do] and the difference was amazing! So, I went and got my eyes tested. Sure enough, they weren't bad, but could be improved upon. With my new specs my PW7 [and every other telly actually] now looks HiDef. Don't waste hundreds on scalers, £200 component leads or mains cleaners, just go down to Specs-R-Us, or whatever and you're sorted.
