Study Notes
Light Regulation in the Eye
- The iris is the part of the eye that regulates the amount of light entering by controlling the size of the pupil.
- The pupil changes size in response to light intensity; constricting in bright light and dilating in dim light.
Function of the Lens
- The lens focuses light onto the retina, allowing for clear vision at various distances.
- It changes shape to help adjust focus for near or far objects, a process known as accommodation.
Main Functions
- The primary function of the lens (or cristalino in Spanish) is to refract light and ensure it is properly directed to the retina.
- Clarity and flexibility of the lens are crucial for maintaining vision quality as the eye ages.
