What is accommodation?
Accommodation is the process by which we focus from near to far or far to near. The lens in the eye changes its shape to change its focus. This process allows our eyes to view clear images of both nearby and distant objects. For example when you look at things up close, the lens becomes thicker to focus the correct image onto the retina. When you look at things far away, the lens becomes thinner. As we age, our lens becomes slightly less flexible and as a result our nearest point of focus moves further away from our eyes.
