THE FOLLOWING TOPICS ARE DISCUSSED IN A ONE HOUR PRESENTATION:

INTRODUCTION: This seminar will present an overview of the role of the eyes and visual system in learning in a school environment. We will discuss the changing role of the computer as a learning tool and how it affects the way we see and learn.

THE EYE: A simplified presentation of the anatomy and functioning of the eyeball and visual system. A comparison of the eye to a camera is used to dispel some misconceptions. Visual processing in the brain is also briefly discussed. The use of two eyes together instead of each individually is a significant feature that separates the human visual system from others. How we use both eyes in conjunction with our focusing system is discussed. Important ramifications of eye position and computer use are noted.

HISTORY OF HUMAN VISION: An historical perspective is developed to show how our visual system was originally designed and used. A comparison with today's visual demands and adaptations is discussed.

LIGHTING AND VISUAL DEMANDS: Our eyes are designed to be used mostly in natural lighting situations. However, with artificial light being so predominant, we must adapt. We will learn to identify risk factors, such as direct and indirect glare, and take steps to correct potentially harmful situations.

VISUAL AND BODY POSTURE: Reading books and papers on a desk differs greatly from viewing a computer screen. It places new demands on our visual system as well as body posture. We are visually oriented; our bodies will often change to ease the stress on our eyes. These effects will be documented and remedies offered.

SOLUTIONS: Environmental and visual solutions include general eye care, computer eyeglasses, contact lenses, screen position & reflections, body posture, working conditions, breaks and more. Specific eye exercises are detailed to assist in the ongoing process of relieving eye stress.

COMPUTER VISION SCREENING: One of the most misunderstood areas of visual function is how the eyes are processing information while viewing the computer. A new and unique software program is now available to perform visual tests right on the computer screen. A complete presentation will describe the program and how to fit it into a current vision screening program.

QUESTIONS: An open question and answer session is scheduled to assure that participants understand the material presented. Any aspect of vision care can be addressed.
