Project 2.4.3: Put Yourself in Someone Else’s Eyes IntroductionImagine that with each day that passes, your vision gets worse. You still hear the voices of the ones you love, but the image you see gets darker every day. The world you knew is slowly disappearing and there is nothing you can do to stop it. You can still communicate with the world around you, but the world will no longer communicate its wonders with images. Not all eye conditions are this serious, but when the unique system of communication in the eye breaks down, what you see will be altered. As you explored in Activity 2.4.2, corrective lenses or glasses can redirect the flow of light to allow for near-perfect vision. Unfortunately, not all disorders of the eye are related to the lens and not all disorders of the eye can be fixed with glasses or contacts. In this activity, you will learn what it is like to see with vision problems, from simple correctable conditions to permanent life-changing diseases. You will use a set of images and alter them to show how the world looks to people with various eye conditions. You will also describe how what this person is seeing is linked to a specific error in the structure and function of the eye.Equipment Computer with Internet accessQuad-photo of yourself with foreground & background Photo editing software (free version)Laboratory journalProcedureWorking individually, have a classmate take a deep photo of you with your phone. Deep means the photos contains elements in front of you, and behind you, and is shot from about 10 feet away from you. Send the image(s) to yourself so you can access them on the class computers.Choose 4 of the 7 eye problems listed below. Research each condition and take ? page of written notes on each of them. Alter 1 of the photos using the free version of and its photo editor to demonstrate how this 1 condition would change how this person sees you. MyopiaHyperopiaAge-related Macular DegenerationGlaucomaRetinitis PigmentosaCataractsColorblindness/Color DeficiencyAlter each remaining photo for the other 3 eye problems you researched. Title each altered image at the top of the photo using the name of the disorder/condition. Paste and format all 4 images to just fit on a single page to be printed, then print 1 page. Use colored pencils to finish any photo alterations to reflect how a person with this condition would see you (the class printer does not print in color). Staple the page into your lab notebook.In your lab journal include the following for each eye problem you chose:Name of the eye problemA diagram of the eye and what occurs in it to cause this conditionA simple written description of the error that produces this disorder and an explanation of how this error changes what a person sees. In your written description, reference key anatomy and think about how the eye functions to allow you to see depth, color, clarity and a proper field of vision. Think about what you have learned about the eye in the past three activities. You may also add any additional information that paints a picture of the disorder including risk factors for developing the disease/condition, interesting facts about the disorder, and treatment options. Be prepared to explain to the class any and all of the eye conditions you have researched.Take notes in your lab journal of the 3 conditions you did not research in your project.After you have reviewed all the conditions in this project, answer the conclusion questions.ConclusionExplain how myopia and hyperopia are related to the lens focusing on the retina.In what ways do you think a person can prepare for losing his/her power of sight?Explain why a girl who is colorblind must have a colorblind father. Other than the use of contact lenses or glasses to correct vision problems, what other types of medical interventions do you think could help individuals with vision disorders? Think about the conditions you have researched and brainstorm potential treatment options. Compare and contrast how a camera works with how the human eye works. List the mechanical parts that would be similar and the parts that would be different.In your laboratory journal, write one to two paragraphs describing what it would be like to live with (age-related) macular degeneration. Think about the day-to-day challenges of this disorder as well as how these changes will affect the person and the family of this person. ................
