If you are in your 40's you may have noticed that seeing up close is getting more difficult. Reading books and working on computers becomes harder for long periods. This occurs because of presbyopia. At a young age, the lens inside our eyes has a great deal of flexibility and therefore focussing power. This ability allows us to see clearly at near distances. When we get to our 40's the lens inside our eyes looses its ability to change shape and therefore focus on near objects. In an attempt to visualise near objects, many of us adjust the distance at which we hold things In order to improve our vision at near we need to consider an optical correction just as one would for near or far sightedness.
