The document outlines a lesson plan for teaching students about myopia (nearsightedness) and hyperopia (farsightedness). It includes objectives, materials, references, and a teaching procedure with steps such as introducing the topic, analyzing it, summarizing, clearing doubts with questions, and assigning students to explain how hyperopia can be corrected using examples. The key points are that myopia occurs when the eyeball grows too long, causing nearsightedness, while hyperopia is caused when the eyeball is too short for distant vision.
