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.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Over the past decade, a variety of new drugs and surgical techniques have been developed to lower intraocular pressure and treat glaucoma. This trend has reinvigorated interest in understanding how and where aqueous humour outflow occurs. Three main pathways are currently known: trabecular, or **_conventional_**, outflow; uveoscleral, or **_unconventional_**, outflow; and subconjunctival outflow. Current methods for imaging these pathways are at varying stages of development, with conventional outflow imaging being the most advanced. Nevertheless, each route possesses a unique biology that can be leveraged in the quest for more knowledge about aqueous humour outflow. Conventional outflow accounts for approximately 90% of aqueous humour flow under physiologic conditions. Here, imaging methods have focused on capturing structural or flow-based features. Optical coherence tomography has enabled researchers to assess ocular tissue in live human subjects..."

In this activity, students will practice the body parts vocabulary. They will also practice simple grammar using the demonstrative pronouns (this-that) for either masculine or feminine.Can-Do Statements:I can recognize all my body parts in Arabic.I can use (this/that) when talking about the body.I can distinguish feminine and masculine forms of the body. 

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Explain how electromagnetic waves differs from sound wavesTrace the path of light through the eye to the point of the optic nerveExplain tonic activity as it is manifested in photoreceptors in the retina

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 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. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

This online exhibit is a visual illusion in which a fuzzy blue dot disappears into a green background. The illusion is created by the tiny jittering movements that your eyes are continually making. Take your investigation further by making your own hands-on fading dot illusion - instructions are at the Exploratorium Snack website (see related link).

This patient education program discusses glaucoma including the anatomy of the eye, types of glaucoma, symptoms and risks, diagnosis, treatment options, and surgery. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

Students are introduced to the Robotics Peripheral Vision Grand Challenge question. They are asked to write journal responses to the question and brainstorm what information they require to answer the question. Their ideas are shared with the class and recorded. Then, students share their ideas with each other and brainstorm any additional ideas. Next, students draw a basis for the average peripheral vision of humans and then compare that range to the range of two different focal lengths in a camera. Through the associated activity provides, students see the differences between human and computer vision.

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.

Vision is the primary sense of many animals and much is known about how vision is processed in the mammalian nervous system. One distinct property of the primary visual cortex is a highly organized pattern of sensitivity to location and orientation of objects in the visual field. But how did we learn this? An important tool is the ability to design experiments to map out the structure and response of a system such as vision. In this activity, students learn about the visual system and then conduct a model experiment to map the visual field response of a Panoptes robot. (In Greek mythology, Argus Panoptes was the "all-seeing" watchman giant with 100 eyes.) A simple activity modification enables a true black box experiment, in which students do not directly observe how the visual system is configured, and must match the input to the output in order to reconstruct the unseen system inside the box.

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

Students learn about glaucoma its causes, how it affects individuals and how biomedical engineers can identify factors that trigger or cause this eye disease, specifically the increase of pressure in the eye. Students also learn how RFID technologies transfer energy through waves and how engineers apply their scientific understanding of waves, energy and sensors to develop devices that measure the pressure in the eyes of people with glaucoma. Students conclude by sketching their own designs for a pressure-measuring eye device, preparing them to conduct the associated activity in which they revise, prototype and evaluate their device designs made tangible with a 3D printer.

Students are introduced to an engineering challenge in which they are given a job assignment to separate three types of apples. However, they are unable to see the color differences between the apples, and as a result, they must think as engineers to design devices that can be used to help them distinguish the apples from one another. Solving the challenge depends on an understanding of wave properties and the biology of sight. After being introduced to the challenge, students form ideas and brainstorm about what background knowledge is required to solve the challenge. A class discussion produces student ideas that can be grouped into broad subject categories: waves and wave properties, light and the electromagnetic spectrum, and the structure of the eye.

Students learn about the anatomical structure of the human eye and how humans see light, as well as some causes of color blindness. They conduct experiments as an example of research to gather information. During their investigations, they test other students' vision, gathering data and measurements about when objects appear blurry. These topics help students prepare to design solutions to an overarching engineering challenge question.

In this service-learning engineering project, students follow the steps of the engineering design process to design a hearing testing device. More specifically, they design a prototype machine that can be used to test the peripheral vision of partially-blind, pre-verbal children. Students learn about the basics of vision and vision loss. They also learn how a peripheral vision tester for adults works (by testing the static peripheral vision in the four quadrants of the visual field with four controllable lights in specific locations). Then they modify the idea of the adult peripheral vision tester to make it usable for testing young children. The class designs and builds one complete prototype, working in sub-groups of four or five students each to build sub-components of the project design.
