Presbyopia is a common eye condition that occurs as you age. People find it difficult to read small words at close distances or to work on the computer for long periods of time. The condition is sometimes called short arm syndrome, because sufferers must often push small print to an arm’s length to be able to read it. When adults are in their forties, the lens of the eye begins to have difficulty accommodating, or in other words, changing its focusing distance. This is due to gradual a thickening of the lens that creates less flexibility.
