  1. Concave and Convex Lenses

  2. Convex lenses • bulge outwards in the center • Bends light inward at a spot just beyond the lens known as the focal point

  3. Concave lenses • Thinner in the middle and thicker on the edges • Curves light rays outward (diverge)

  4. How You See • Your Eye • Convex Lens • Image focuses on the retina near the optic nerve • Objects appear upside down until the brain turns the object right side up

  5. Lenses to the Rescue • Far Sighted • Corrected by using a convex lens • Shortens the focal point

  6. Lenses to the Rescue • Near Sighted • Corrected by using a concave lens • Expands the focal point
