In this activity, students determine their own eyesight and calculate what a good average eyesight value for the class would be. Students learn about technologies to enhance eyesight and how engineers play an important role in the development of these technologies.
The butterfly can fly around using its wings and sees where it is going through its eyes. The spiracles allow the butterfly to breathe and the legs are what it uses to walk or crawl around on. The antennae help the butterfly know where it is going. The proboscis is what the butterfly uses to drink nectar from flowers.
Students examine the structure and function of the human eye, learning some amazing features about our eyes, which provide us with sight and an understanding of our surroundings. Students also learn about some common eye problems and the biomedical devices and medical procedures that resolve or help to lessen the effects of these vision deficiencies, including vision correction surgery.
This patient education program explains cataracts including the symptoms, diagnosis, complications, and treatment options. It also discusses the risks and benefits of surgery and what to expect after the procedure. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

This dataset has been added as an experimental use of Open Context for public health data sharing applications. Corneal ulceration is a major cause of blindness in many parts of the world, but in South East Asia the WHO estimates that there are as many as 12 million blinding ulcers every year in a population of 1.6 billion. Now that we know the main causes of these ulcers it is possible to prevent the occurrence of most of them with simple, grass-roots, public health measures. The development of these public health programs were a result of findings of this corneal ulcer study in Madurai, India in 1994.
This patient education program explains how diabetes affects eyesight, specifically the prevention and treatment of diabetic retinopathy. It also reviews eye anatomy, other eye problems, and their treatment.

Using edge detection and distance measurements to detect the pupil from an image of the eye.
This lesson describes the function and components of the human nervous system. It helps students understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is also discussed in this lesson.
This series of research talks by members of the Department of Brain and Cognitive Sciences introduces students to different approaches to the study of the brain and mind. Topics include: "From Neurons to Neural Networks" "Prefrontal Cortex and the Neural Basis of Cognitive Control" "Hippocampal Memory Formation and the Role of Sleep" "The Formation of Internal Modes for Learning Motor Skills" "Look and See: How the Brain Selects Objects and Directs the Eyes" "How the Brain Wires Itself"
Sensation and perception are the processes by which we absorb information from environmental stimuli and convert it into data that our brains and bodies use to modify behavior. This course begins with sensation, the physical process by which we use our sense organs to respond to the environmental stimuli around us. Perception refers to our interpretation of stimuli. In this course, the student will identify the ways in which these processes can fail, the biology of both the hearing system and the visual system, and how the other senses (smell, taste, and touch) affect perception. Upon successful completion of this course, students will be able to: describe the sensory systems; distinguish between sensation and perception; explain how sensory and perceptual processes shape our experience of 'reality;' explain the basic principles of classical psychophysics; explain how sensation and perception relate to cognition; explain how human sensory systems respond to energy in the physical environment (i.e. light waves, air pressure, chemical molecules, etc.), transforming it into a perceptual experience that the brain can understand (i.e. sight, sound, smell, etc.); compare and contrast the major theoretical perspectives on sensation and perception, including direct perception, indirect perception, and the information processing perspective; compare and contrast the five sensory systems in terms of their sensory/anatomical set-up and perceptual organization; explain the roles of evolution, development, society, prior knowledge, and inference in our perceptual judgments and our conscious experiences; identify and define the leading terms, concepts, theoretical perspectives, empirical findings, and historical trends in the study of sensation and perception; compare and contrast psychological principles, theories, and methods as they pertain to sensory and neurological systems; critically read, understand, and evaluate scientific literature, understand and use scientific and technical vocabulary, and synthesize information from multiple sources.
