B10.6 Common problems of the eye

This final lesson in the AQA B10 series lesson. The first of two starters to choose from is ‘Near and far’ where students complete an accommodation activity involving the muscles and ligaments in their eyes followed by discussion. The main part of the lesson introduces the concept of accommodation before students annotate diagrams of the eyes to show changes in the eye for near and distant objects. This is followed by students measuring their range of accommodation. Two common eye defects (myopia and hyperopia) are then introduced and further explained in terms of how distant and near objects appear and the focus of images on the retina. Further, students explore the treatment for eye defects. The Plenary includes a gap fill about how the eye focuses on near and distant objects. Homework and exam questions based on this lesson are also included as well as mark schemes.
