Activity (Hands-On)Grades 3 - 5

20/20 Vision

Students measure their own eyesight and calculate the average eyesight value for the class. They learn about technologies to enhance eyesight and how engineers play an important role in the development of these technologies.

A photograph shows a young woman with glasses and a portion of an eye chart in the background.Students measure their eyesight quality.

Engineers have created eye devices for people who have vision difficulties, including glasses and LASIK (laser-assisted in situ keratomileusis) eye surgery equipment. Electrical engineers have applied their understanding of the eye to create microchips that can be implanted into the back of the eye. The microchip works as a light sensor for people whose natural light sensor does not work.

After this activity, students should be able to:

  • Describe vision.
  • Explain how vision is measured.
  • List several technologies designed by engineers to adjust and enhance vision.
