Vision condition that is related to ageing. The crystalline lens of the eye loses its flexibility and as a consequence the ability to focus on images at a normal reading distance.
Presbyopia is when your eyes gradually lose the ability to see things clearly up close. It is a normal part of aging. In fact, the word “presbyopia” means “old eye” in Greek. You may start to notice presbyopia shortly after age 40. You will probably find that you hold reading materials farther away in order to see them clearly.
