Presbyopia is a natural age-related condition in which the eye loses its ability to change focus from distance to near vision. The word presbyopia, from Greek language, means aging eye. The symptoms of presbyopia usually appear in the fifth decade of life, i.e. ages 40 to 50. The first symptom most people notice is difficulty focusing at close length to read small print (assuming the eye has proper distance vision focus), particularly in dim lighting conditions. Many people compensate for this condition by holding reading material further away until they eventually may complain that their arms are “too short”. Most of these folks start to use reading glasses, often called either cheaters or readers. In people whose eyes are myopic, or “near-sighted”, the onset of presbyopic symptoms may cause them to take off their distance vision corrective lenses in order to see up close. People who need spectacle vision correction for both far and near vision often start to use one of several bi-focal lens options after the onset of presbyopia begins.
