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 curvature 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
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 and discuss the implications of this technology for society
The Encyclopedia of Life is a database that aims to have an electronic image of each species of organism to be found on the planet. Best results are obtained when searched by scientific name.
The Eye
The eye is one of our major sense organs. It gathers light information and transforms it into a signal that is used by the brain to formulate an appropriate response. How does this process work? What are the structures involved, and what do.
