What is a cataract? A cataract is a cloudy area in the lens of your eye. Cataracts are very common as people get older. In fact, more than half of all 80 Americans 80 or older either have cataracts or have had surgery to get rid of cataracts. Cataracts can lead to vision loss.

How does a cataract affect vision? A cataract scatters and blocks the light as it passes through the lens, preventing a sharply defined image from reaching your retina. As a result, your vision becomes blurred. Image: https://www.glaucomaassociates.com/glaucoma-and-cataracts/
How does cataract surgery help people? Restores clear vision allowing people to enjoy life better. Reduces the risks of falls, a leading cause of injury and death in older adults. New research indicates that cataract surgery may reduce the risk of dementia. https://www.nia.nih.gov/news/cataract-removal-linked-reduction-dementia-risk
Take good care of your eyes! Here are 10 ways to help keep your eyes healthy: 1. Eat a healthy balanced diet 2. Exercise regularly 3.

Teacher Notes: Dr Patricia Bath Summary: Students are introduced to Dr. Patrician Bath who developed a surgery for eye cataracts, and they will learn about the anatomy of the human eye and vision. Lesson Length: 2 class periods (55 minutes): Optional 3rd Period (eye dissection) Next Generation Science Standards (NGSS) Covered: Structure, Function, and Information Processing 4-PS4-2: Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen. 4-LS1-2: Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways. Common Core State Standards (CCSS) ELA Covered: RI.4.4 Determine the meaning of general academic and domain-specific words or phrases in a text relevant to a grade 4 topic or subject area. RI.4.7 Interpret information presented visually, orally, or quantitatively (e.g., in charts, graphs, diagrams, timelines, animations, or interactive elements on Web pages) and explain how the information contributes to an understanding of the text in which it appears.
This lesson was brought to you by ScienceSaves. The #ScienceSaves campaign demonstrates how science has benefited human progress and how it offers humanity the tools to address today s most pressing challenges.
