When you are trying to introduce how human’s vision works, using eye diagram will be one of the best options. In telecommunication, an eye pattern, also known as an eye diagram, is an oscilloscope, display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. Well, take a peek inside the human eye with this eye-catching eye diagram! See a simple eye diagram and learn vocabulary words that will help your child understand how his vision works.

In an ideal world, eye diagrams would look like rectangular boxes. In reality, communications are imperfect, so the transitions do not line perfectly on top of each other, and an eye-shaped pattern results. On an oscilloscope, the shape of an eye diagram will depend upon various types of triggering signals, such as clock triggers, divided clock triggers, and pattern triggers. Differences in timing and amplitude from bit to bit cause the eye opening to shrink.



A properly constructed eye should contain every possible bit sequence from simple alternate 1’s and 0’s to isolated 1’s after long runs of 0’s, and all other patterns that may show up weaknesses in the design. Eye diagrams usually include voltage and time samples of the data acquired at some sample rate below the data rate.



By using these eye diagrams, you can teach and show your kids how their eyes work. Print these eye diagram and introduce the anatomy of eye to your children!
