Literally "old vision", it represents a natural aging process of the eye. It starts to affect most people around the age of 40. Normally, when a close object is viewed, the lens will change shape or "accommodate" to focus light on the retina. With Presbyopia, the lens can not sufficiently reshape and glasses are required for close viewing. If someone has laser vision correction for nearsightedness and is already presbyopic (40+ years of age), they will then need correction for reading. These are typically just the store bought magnifying glasses.
