Convergence
is the name given to the movement of the eyes when they move inward toward
each other, as when reading. Convergence Excess (CE) occurs when the eyes
move inward too much when reading. In other words, the eyes are mildly
crossed when looking at a near object. This excessive inward movement can
cause words to appear jumbled, blurred, or even doubled.
In
a normal working ocular system, the accommodation system (the focusing
system for near) and the convergence system (the eye alignment system)
work together to make the words on the page appear clear. For people with
CE, the accommodation and convergence systems are not working in unison,
which causes the words on the page to appear blurred or double.
Those who
suffer from CE often have symptoms of:
Eyestrain
Reading below grade level
Blurred vision when reading
Inattentiveness
to school work
Double
Vision
Headache
Loosing
their Place when reading
