Episode notes
The Marvel of Vision
- The eye's ability to process light into clear images is remarkable.
- This intricate process allows us to perceive the world around us, including colors and objects.
Cornea's Role in Focus
- The cornea provides about 75% of the eye's focusing power, not the lens.
- The lens, made of the protein crystalline, further focuses light onto the retina.
Rods vs. Cones
- Rods, sensitive to light, handle night vision but struggle with color and sharp details.
- Cones, concentrated centrally, perceive color and fine details but are less light-sensitive.
