Presbyopia will eventually affect the vision of every American over the age of 40 years old. It is an age-related visual impairment that is the direct result of our body’s natural ageing process. The progression of this eye condition is often gradual.
The exact cause behind presbyopia is not fully understood at this time. Research suggests a correlation between the loss of elasticity in the natural crystalline lens of the eye and the muscles that surround the lens.
The lens of your eye typically retains its elasticity and flexibility for the first 4 decades of your life. When the lens is soft and flexible, it provides you the ability to focus quickly and with accuracy on the objects around you. It is believed that as we age, the proteins in our lens begin to change, progressively making the lens rigid and gradually reducing its flexibility over time.
The hardening of your eye’s lens leads to difficulty focusing on objects. This is why you tend to see people over the age of 40 adjusting the distance of their reading material in order to be able to see it properly.
While age is the typical culprit of your presbyopia, it can also result from trauma, a systemic disease, heart disease, or the side effect of a drug.
The onset of presbyopia is gradual. Symptoms will present as:
Presbyopia is one of the easiest eye conditions to treat. The most common first step is corrective eyewear via contact lenses1 or eyeglasses2.
As a result of its ongoing progression, your prescription will need to be increased as you age.
If you would like to avoid the hassle of eyeglasses and contacts lenses, corrective eye surgery3 is a viable treatment option for the right candidate. While the results of this surgery are not permanent for presbyopia, they will last for a considerable amount of time.
