What Is Presbyopia And How Common Is It?

Question: What is presbyopia and how common is it?

Answer: Presbyopia, which is another eye error, is actually 100% common. What I mean by that is that we're all going to be what's termed presbyopic. It simply refers to the fact that once we get into our 40's or 50's we start losing the ability to focus up close on things. And that's because of the lens of our eye which can change shape throughout most of our life, is no longer able to change shape to a large enough extent to overcome the blurriness that we might see up close.
