    Conclusion

    Now that you have finished  your adventure you should feel a sense of accomplishment!!! Excellent Job! Here is a review of what you have learned about the Eye.

    • Light is focused primarily by the cornea — the clear front surface of the eye, which acts like a camera lens.
    • The iris of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the back of the eye by automatically adjusting the size of the pupil (aperture).
    • The eye's crystalline lens is located directly behind the pupil and further focuses light. Through a process called accommodation, this lens helps the eye automatically focus on near and approaching objects, like an autofocus camera lens.
    • Light focused by the cornea and crystalline lens (and limited by the iris and pupil) then reaches the retina— the light-sensitive inner lining of the back of the eye. The retina acts like an electronic image sensor of a digital camera, converting optical images into electronic signals
    • The optic nerve then transmits these signals to the visual cortex — the part of the brain that controls our sense of sight.
    • The retina consist of Rods and Cones
    • The rods allow us to see in dim light while the Cones allow us to see in bright light.
