Presbyopia is a natural change in our eyes’ ability to focus. It occurs when the crystalline lens of the eye loses its flexibility, causing objects to appear blurry. Symptoms take years to develop and typically begin to show in the early- to mid-40s.The effects of presbyopia can be corrected with glasses or contact lenses, including multifocal and progressive lenses; monovision; and conventional or laser surgery, such as PRK, monovision LASIK, and intraocular lenses (IOLs).
