As we age, there are a number of people that begin to notice a difference in change in their seeing. Some people notice they have a hard time seeing things up close while others may have a hard time seeing things from a distance. This becomes obvious once we hit age 40. This is because the eye’s lenses happen to get a little less flexible and this leads to trouble with being able to focus on certain objects at various distances.
