Presbyopia is the natural, age-related reduction in the eye’s ability to focus on near objects. It typically becomes noticeable from the early to mid-40s and progresses gradually over time. 

While it is a normal part of ageing rather than a disease, presbyopia can significantly affect everyday tasks such as reading, using digital devices, working at a computer or viewing fine detail. 

Modern surgical options provide effective, long-term solutions for suitable candidates seeking greater visual independence. 

What Is Presbyopia? 

To see clearly at different distances, the natural lens inside the eye changes shape. When looking at near objects, the lens becomes more curved to increase focusing power. When looking into the distance, it relaxes and flattens. 

From around the age of 40, the lens gradually becomes thicker and less flexible. As this flexibility reduces, the eye loses its ability to adjust focus easily between distances – particularly for near tasks. This process is known as presbyopia. 

Unlike myopia or hyperopia, presbyopia is not caused by the shape of the eyeball or cornea. It is the result of natural ageing changes within the lens itself. 

The progression is gradual. Most people first notice subtle difficulty with small print or prolonged reading. Over the following 10–20 years, near focusing ability continues to decline before eventually stabilising. 

Presbyopia can occur on its own or alongside other refractive errors such as short-sightedness, long-sightedness or astigmatism.
