Presbyopia
Hold the book up close and the
words appear blurred. Push the book farther away, and the
words snap back into sharp focus.
That’s how most of us first
recognize a condition that eye care professionals call
presbyopia, a name derived from Greek words meaning
"old eye." Eye fatigue or headaches when doing
close work, such as sewing, knitting or painting, are
also common symptoms. Because it is associated with
aging, presbyopia is often met with a groan -- and the
realization that reading glasses or bifocals are
inevitable.
What causes presbyopia?
Recent research shows that the lens in the eye continues
to grow as we age. Eventually it reaches a point, around
the age of 45 that it is too big for the muscles that
normally change it's shape to work effectively. The loss
is gradual - but inevitable.
