Reading between the lines
TLF ID L57
Test the vision of four people to identify vision problems: myopia, hyperopia or presbyopia. Compare effects of corrective lenses on reading at different distances. Look at a cross-section of the eye showing focal variations linked to a vision problem. Explore how common vision problems are by doing a survey. This learning object is one in a series of two learning objects. The series is also packaged as a combined learning object.
