In this activity, students determine their own eyesight and calculate what a good average eyesight value for the class would be. Students learn about technologies to enhance eyesight and how engineers play an important role in the development of these technologies.

In this lesson, students examine the structure and function of the human eye, learning some amazing features about our eyes, which provide us with sight and an understanding of our surroundings. Students also learn about some common eye problems and the biomedical devices and medical procedures that resolve or help to lessen the effects of these vision deficiencies, including vision correction surgery.

Students become familiar with the similarities and differences between electronic and printed text by comparing the textual aids included in a textbook with those of an educational website.

This lesson includes an Internet exploration that focuses on the roles of the eye and brain in the perception of color. It includes an introduction to the anatomy of the eye, including the functions of rods and cones. It is recommended that students complete the first 2 activities (Light 1 and Light 2) prior to this activity.

Did you see that? Hopefully after these fun experiments in our series Science in the Dark you will have a greater appreciation for the night. Now let’s “see” how our eyes are affected by the dark!

We have created helpful clips if you're unable to watch the full video:
