Common Causes of Presbyopia

The exact causes of presbyopia are not completely known, but it is believed to be a part of the natural aging process. This condition is characterized by an inability to focus on objects which are nearby which results from stiffening of the human lens which makes it difficult for the lens to change shape as necessary to focus on objects which are near.

Presbyopia can be diagnosed with a simple eye exam, but most patients can easily recognize the symptoms of this condition. Patients who begin to have difficulty reading because the words appear blurred, have difficulty reading at night or experience discomfort, fatigue or headaches when doing work requiring them to focus on near objects or words should consult their eye doctor for an evaluation.
