Science Buddies: "Ask an Expert"

The topic I want to do is how a person's eye color affects their sensitivity to light. I need to have a topic that is measurable because I must be able to create a graph. I don't think that sensitivity can be measured, but how could I test this idea and how would I graph the data? Thank you!

That is a really interesting topic!
I can't think of ways to measure sensitivity, but maybe you can ask them questions and maybe graph the degree of light sensitivity (number of questions they answered "yes" to).
For example, these questions: (http://irlen.com/light_sensitivity_self_test.php)
