- Light bends when it passes through a liquid
- Refraction is the bending of light
- Lenses can bend light and magnify objects
- Binoculars, hand lenses and telescopes use lenses
- Human eyes use lenses to focus light
- Light from a source travels to the eye
- The lens in the eye focuses the light at a focal point
- The brain interprets signals from the focal point, allowing us to see
