Opinion | Ageing Eyes: Don’t Accept Poor Vision as a Normal Part of Ageing

As we grow older, it is easy to assume that changes in eyesight are simply another part of life. Holding a book farther away, needing brighter light to read or finding it more difficult to see clearly at night may gradually become part of everyday life. While some changes in vision are expected, poor or progressively declining eyesight should not simply be accepted as inevitable.

With World Sight Day being observed on October 8, this is an important reminder that changes in vision deserve attention rather than being automatically attributed to age.

One of the most common changes is presbyopia, a condition in which the eye gradually loses its ability to focus on nearby objects. It usually becomes noticeable in middle age, when people start holding books, newspapers or their phones farther away to read comfortably. They may also need more light for reading or find it harder to focus on small print for long periods. Presbyopia is a natural change and can generally be corrected with appropriate glasses or other vision correction options.

The important distinction is between changes that are expected and those that may indicate a problem requiring medical attention. A gradual need for reading glasses is very different from steadily worsening vision, difficulty performing everyday activities or a significant change in the quality of sight. People can also become so accustomed to gradual changes that they may not realise how much their vision has changed until it begins to interfere with daily life.

Cataract, for example, can cause gradually blurred or hazy vision, glare or halos, and difficulty seeing at night. Because these changes can develop slowly, people may adapt to them without realising how much their eyesight has deteriorated. Similarly, glaucoma can progress without obvious symptoms until significant damage has occurred, while retinal disorders may also affect vision gradually. This is why a proper eye examination is important when there is a noticeable change in vision.

Changes in daily habits can also provide important clues. A person may stop driving at night, avoid reading for long periods, increase the brightness of the television or rely increasingly on others for everyday tasks. When activities that were once routine become difficult, it is worth finding out why. Good vision is closely linked to independence, mobility and confidence, particularly when it comes to driving, navigating unfamiliar places or managing everyday tasks safely.

Certain symptoms should never be dismissed. Sudden loss or significant blurring of vision, flashes of light, a sudden increase in floaters, a curtain-like shadow across the field of vision, double vision or severe eye pain can require urgent medical attention. Some eye conditions can cause permanent vision loss if treatment is delayed.

Regular eye examinations are important even when a person feels that their vision is satisfactory. The frequency should depend on age, overall health, family history and existing risk factors. People with diabetes, hypertension, high myopia, a family history of glaucoma or previous eye problems may need closer monitoring. An examination can also help determine whether a change in vision is simply related to focusing or whether it needs further investigation.

Getting older is inevitable, but unnecessary vision loss does not have to be. Modern eye care can identify many problems early, when treatment or appropriate management may help preserve useful vision.

Good eyesight supports independence, mobility, reading, communication and the ability to continue everyday activities with confidence. If your vision is changing, an eye examination can help determine whether it is an expected change or something that needs attention. Growing older may change the way we see, but losing useful vision should never simply be accepted as a normal part of ageing.
