Special Senses of the Eye and Ear Lesson 4-2: The Eyeball and Seeing
The Eyeball and Seeing • Eyeball
The Eyeball and Seeing • Keynote: “ The cornea protects the eye, and by changing shape, provides about 60% of the eye’s focusing power. The pupil controls the amount of light entering the eye. The lens changes its shape to focus rays of light onto the retina.”
The Eyeball and Seeing • Keynote: “Both the cornea and lens refract light rays. Neither has a blood supply which compromises healing from injury or disease.”

Word Analysis and Definition • Answer: Place the structures in order from the outside of the eyeball to the innermost portion of the eyeball: - outermost: cornea iris pupil lens - innermost: retina
The Eyeball and Seeing • Eyeball - retina
The Eyeball and Seeing • Keynote: “Rods of the retina perceive only dim light, and not, color. Cones of the retina perceive bright light and color. Rods and cones are called photoreceptor cells.”
The Eyeball and Seeing • Eyeball - segments of the eye
