If you have good eyesight, you really don't know how lucky you are. I can't imagine being able to just see, without spending £20 a month on contacts and £300+ on each pair of glasses. (Yeah, you didn't realise it was that expensive, right?) That's not to mention the annoyance of contacts drying your eyes out or glasses getting smudged. But what's also very frustrating is trying to find a pair of glasses that you actually like. This is the accessory I wear more than anything else, yet over the years I've struggled to find a pair I'm happy with.
