Snellen Chart

I just got my glasses done and noticed that even with my glasses, I couldn't see the bottom row of the Snellen Chart. Worried that my glasses wasn't made well, I asked my optician whether that was normal - and she said yes.

Before I continue, let me show you a picture of a snellen chart:

Apparently, most people can see up to the red underlined row. And that already is 'perfect eyesight' but few could actually read beyond that red underlined row. I wonder how many readers can actually read beyond the red line. I know I can't... even with glasses.

Anyway, here's some more trivia for you:

Why is the letter "E" on top of all eye charts?

So uhm, the people who can read the letters well below the red line have a superhuman vision? :D Kidding aside, some people may be able to read those. At least, you're able to see what needs to be seen perfectly, so your glasses really work for you. The Snellen Chart does have some interesting stuff other than those letters, huh.
