When you go to the eye doctor to get your eyes examined, you know that you are going to get to read the eye chart, either, with a lot of squinting, or a no-problemo ease.
Of course, the easy part, is the top of the chart (for those with fair vision). It's like elementary chart reading. And the lower part of the chart, typically, may be a wee-bit harder to distinguish and read, for the more near-sighted.
Reading the chart to your doctor, may seem a bit silly at first. However, it's when you get to the bottom, and when the doc. says to you: "better here; or better here?" -- that you may start to see, that reading the eye chart, is not necessarily, such a piece of cake, after all. Guessing, if you are not sure of a letter, really is not something that helps you, because (of course), you don't have anything to gain by doing that.
If you're lucky and have good vision, that is something to really appreciate. Your chart reading, may really be an easy one.
