34.18 Vision and Visual Perception

Vision

One of the most important medical requirements for a pilot is to have good vision.

Having good vision is crucial for pilots as it directly affects their ability to safely operate an aircraft.

Pilots must meet specific visual acuity requirements to obtain and maintain their pilot's license.

The Eye

The eye is an incredible organ that allows us to perceive the world around us, capturing light and converting it into electrical signals that our brain interprets as images.

Our eyes have complex structures that work together to focus light and send signals to the brain.

They can adjust to different lighting conditions, detect colours, and even perceive depth and motion.

34.18.2 Distinguish between rod and cone cell functions and distribution in the retina.

Rods

Rod cells are responsible for our night vision and detecting low levels of light.

They help us see in dark environments and are more concentrated towards the outer edges of the retina.

Rod cells not only help us see in low light conditions, but they also play a crucial role in our ability to perceive shapes and movement.
