Consider the following animation
How many boats would be visible with each condition?
What makes the four boats easy or hard to see?
The ability to gain information when a person has each condition can
depend on the objects chosen.
Different factors should be considered when analysing this simulation.
- size of the objects
- light on and around the object
What effect will the size of an object have if a person has a central
visual field loss?
is the effect of contrast if a person has a corneal or lens problem?
effect will the position of the object have if a person has retinal
the effects of each condition in relation to normal vision
