Sometime in the early-to-mid-forties, you start to lose flexibility in the eye’s lens. This decreased flexibility makes it difficult to view objects up close. People with presbyopia often notice they need more light to read, and have to hold reading material at arm’s length to focus.
Presbyopia is a vision condition in which the shape of the crystalline lens of your eye changes. These changes make it difficult to focus on close objects. Presbyopia is a natural part of the aging process of the eye. It is not a disease, and it cannot be prevented.
Unlike nearsightedness, farsightedness or astigmatism, presbyopia isn’t caused by an eye shape. It’s simply a normal part of the aging process, and since we all age, presbyopia affects everyone. It also worsens with each passing year.
