Whether you are nearsighted, farsighted or even if you do not need any visual correction, you will likely need the help of reading glasses when you reach your 40's. This is called presbyopia (prez-bee-oh-pee-uh). Unlike nearsightedness or farsightedness, this change is a natural age-related change that occurs in everyone. With age, the structures within the eyes change and can no longer shift focus from far to near. Some of the early signs and symptoms of presbyopia are difficulties with near work or computer use, eye strain, and fatigue towards the end of the day. Many people are currently using bifocal or multifocal eyeglasses to help correct presbyopia.
