Slide 1 - EYE The eye is an extension of the brain
Slide 2 - Eye brain proxomity Can you see : the optic nerve bundle? Spinal cord?
Slide 3 - Cross section You must know the position of: Retina Lens Cornea Sclerotic Optic nerve Cilary muscles Suspensory ligaments
Slide 4 - Retina – receives the image Full of light receptors which are sensitive to: Colour Light levels Massive blood supply is also needed Fovea is the main focal point and has greatest density of light receptors
Slide 5 - Retina receptors Light receptors are called rods and cone
Slide 6 - Focusing on objects The lens and cornea focus the light on the retina
Slide 7 - Focusing The lens job is to make the rays hit the same point The red rays will be out of focus
Slide 8 - Bending light Light is refracted and bent to focus it as it passes through the lens Lens thickness can be changed so the amount of bending is changed
Slide 9 - Near vision to bend the light more to focus it Fat lens needed
Slide 10 - Distance vision Rays enter the eye closer together Need less bending Thinner lens needed
Slide 11 - Changing lens thickness The lens is slightly elastic, its relaxed state is short and fat. Cilary muscles are attached to the lens, when contracted they pull the lens thin
Slide 12 - Controlling light levels Your eye are very sensitive and can be damaged by harsh light. Your iris controls light allowed into the eye by changing the size of the pupil
