9.5 Option – Communication: 3. Refraction of light in the eye
Syllabus reference (October 2002 version)
3. The clarity of the signal transferred can affect interpretation of the intended visual communication
Students learn to:
identify the conditions under which refraction of light occurs identify the cornea, aqueous humor, lens and vitreous humor as refractive media identify accommodation as the focusing on objects at different distances, describe its achievement through the change in strength of the lens and explain its importance compare the change in the refractive power of the lens from rest to maximum accommodation distinguish between myopia and hyperopia and outline how technologies can be used to correct these conditions explain how the production of two different images of a view can result in depth perception
Students:
plan, choose equipment or resources and perform a first-hand investigation to model the process of accommodation by passing rays of light through convex lenses of different focal lengths analyse information from secondary sources to describe changes in the shape of the eye’s lens when focusing on near and far objects process and analyse information from secondary sources to describe cataracts and the technology that can be used to prevent blindness from cataracts to discuss the implications of this technology for society
