Presbyopia is caused by an age-related process that becomes noticeable in the early to mid-forties. Presbyopia is caused by a gradual loss of flexibility within the lens inside your eye. The eye's lens stiffens with age, so it is less able to focus when you view something up close. The result is blurred near vision. These age-related changes occur within the proteins in the lens, making the lens harder and less elastic with the years. Age-related changes also take place in the muscle fibers surrounding the lens. Some signs of Presbyopia include the tendency to hold reading materials at arm's length, blurred vision at normal reading distance, the need for brighter and more direct light for reading, and eye fatigue along with headaches when doing close work. Reading glasses, bifocals, trifocals or contact lenses are prescribed to help compensate for Presbyopia.
