Physiological Optics: An Introduction to Human Sight and Vision
Copyright :
Physiological optics is how the brain uses the eyes to create clear, aligned imaging for downstream processing – and the challenges it faces in making this happen. Where there is a visual impediment due to trauma or development, visual signal acquisition will be affected and in turn degrades downstream processing. If you consider all that is connected to vision, you’ll start to get an idea of what this can mean: Cognition, Affect / Emotional Function, Fine Motor Control, Gross Motor Coordination, Locomotion, Balance, Orientation / Motor Reflex Responses, Obstacle / Threat Avoidance – it’s everything!
- Advance your understanding of human vision and how it plays into the work you do.
- Learn about sight (visual signal acquisition), glasses, and how these affect behavior, learning, and rehabilitation.
- How people receive light naturally and what it is like to have nearsight, farsight, astigmatism, and more.
- What our eyes do to try to accommodate for any lack of clarity.
- How this affects us in daily life and in clinic.
- What can and should be done about it, accounting for purpose and age.
Vision is a complex neurological experience the most complex sensory experience. Explore a down to earth introduction to refraction, how we focus light with our eyes to see the world clearly – and what happens when things go awry.
