Serious Conditions And Other Factors That Cause Blurry Vision

Presbyopia

Presbyopia is the medical term for the normal loss of focusing ability that happens as individuals age. The effects usually set in at some point after the age of forty. The first symptom patients tend to experience is trouble clearly seeing small print when reading books or trying to decipher text messages. Presbyopia happens to everyone, even if they've never had a vision problem before. Nearsighted individuals will also notice their close vision is beginning to become blurred in addition to their distance vision. The condition occurs when the eye's natural lens gradually thickens and loses flexibility, causing it to be unable to focus as well. The change is caused by proteins found within the lens, which cause the lens to lose its elasticity and become harder. There are also changes in the muscle fibers around the lens as individuals age. Specifically, they become tighter and don't have as large a range of motion, further complicating the ability to focus.
