Physiological Optics: An Introduction to Human Sight and Vision
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!
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.
Charles Boulet, BSc, BEd, OD, has been a loud advocate for essential vision care for underserved populations and was instrumental in promoting Alberta’s Child Vision Assessment Act in 2014, which sought to achieve common vision exams for all children in the province. Along with his clinical work, Dr. Boulet is involved with ongoing research and advocacy with professionals from around the world, including a handful of publications and a growing library of online content.
