73Sjöbba: If you have 20/20 vision, it means that when you stand 20 feet away from the chart you can see what the "normal" human being can see. (In metric, the standard is 6 meters and it's called 6/6 vision). In other words, if you have 20/20 vision your vision is "normal" -- a majority of people in the population can see what you see at 20 feet. (From here on, please assume that the word normal has quotes around it.)
Vi tycker om dig jättemycket, men ibland går topplocket och det skrivs massa tok. Oftast menar vi det kanske inte, men ibland har vi kanske också lite rätt.
