Presbyopia

If you are in your 40s, you may have noticed that seeing up close is getting more difficult. Reading books and working on computers is more complicated for long periods of time.

It happens because of presbyopia. When we are young, the lens (natural lens inside the eye) is relatively flexible and therefore has a focusing power by modulating its shape. This allows us to see clearly at close distances.

     

When we reach our forties, the lens loses its ability to change shape and therefore to focus light from nearby objects. In order to try to see up close, we are then forced to stretch out our arms to move objects away and adjust the distance at which we hold things.

 

In order to improve our near vision, we must consider optical correction as we would for near or far vision. Glasses, contact lenses or refractive surgery (LASIK, clear lens surgery, multifocal IOL ) may be considered to treat presbyopia.
