Tests for the two functions are therefore complementary and obtaining a measure of both will give a fuller description of visual deficits than will one alone.

A child with visual impairment who retains good contrast sensitivity will benefit from enlargement of tasks he or she sees large faint objects well. A child with an equivalent acuity but with reduced contrast sensitivity has a much more severe impairment, and will not get the same benefit from enlargement. Large objects as well as small objects are difficult to see. So a measurement of contrast
