Presbyopia is the normal process of ageing, where the natural lens of the eye loses some of the flexibility that characterises a younger eye.

As we age, our body tissues begin to lose their elasticity. Thus, when the lenses in the eyes lose some of their elasticity, they begin to lose some of
their ability to change focus for different distances. The loss is gradual. Long before we become aware that seeing close up is becoming more difficult,
the lenses in our eyes have begun losing their ability to flatten and thicken. Only when the loss of elasticity impairs our vision to a noticeable degree
do we recognize the change. 
Presbyopia usually becomes noticeable in the early to mid-forties and since the effects of presbyopia continue to change the ability of the crystalline
lens to focus properly may worsen over time. Presbyopia is a natural part of the aging process of the eye. It is not a disease and it cannot be prevented.

Symptoms of Presbyopia include:

• Decreased focusing ability for near objects
• Eyestrain 
• Tired eyes 
• Headache

Since presbyopia can complicate other common vision conditions like nearsightedness, farsightedness and astigmatism periodic changes in eye glasses will
be necessary to maintain clear and comfortable vision.

Laser eye surgery cannot improve presbyopia.
