How Do Eyeglasses Work?
Medium
Have you ever wondered why you need to wear glasses? In this project, you'll learn how eyeglasses work to help us see better. Our eyes have to do a lot of things perfectly for us to have perfect sight. If just one of those things is not quite right, we need glasses. But the glasses have to be made just for you and your unique eyes. Eyeglasses work by bending light beams so that they meet right at the back of our eyeballs on the retina.
Hypothesis
The hypothesis is that eyeglasses help us see better by bending light beams so that they meet right at the back of our eyeballs on the retina.
Method & Materials
You will hold a pair of glasses out at the end of your arm, look at the view, and look at the lenses. You will also look at several different pairs.
You will need a few friends who wear glasses (perhaps your classmates at school).
Results
Through this experiment, you will learn that glasses for nearsighted people make the view look smaller, glasses for farsighted people make the view look bigger or even upside down, and glasses for people with astigmatism change the shape of the view, stretching it out and maybe twisting it. You will also observe that nearsighted people can see near, but not far away, and farsighted people can see far, but not close up.
Why do this project?
This science project is interesting and unique because it allows you to observe the differences between different types of glasses and how they help people with different vision problems.
Also Consider
Experiment variations to consider include testing different types of lenses and observing how they affect vision, or testing different types of frames and observing how they affect vision.
