What Is Presbyopia?
Presbyopia is the gradual decline of your eyes' ability to focus on nearby objects, causing those objects to appear blurry and out of focus. If you've noticed you have to hold a book farther away to read than you used to, you may be experiencing presbyopia.
Presbyopia Is Natural
Most people experience presbyopia in their mid-40s. Much like adjusting the focus on a camera, a healthy eye lens flexes and changes shape to properly focus on objects at different distances. With age, the lens loses its ability to flex and change, making it difficult to focus on near objects.
