Health experts explain why eyesight worsens as we age - and how to prevent it

dailyrecord.co.uk:

As we age, we begin to feel more aches and pain, parts of us sag that didn't before and some of us may become more forgetful.

This is all a part of getting older. A decline in eyesight is also a sign of ageing, with conditions such as cataracts being brought into more day-to-day conversations.In order to try and preserve your eyesight for as long as you can, it is crucial to understand the reasons behind these changes and how to manage them.

Several optometrists have given their insight into the science of why these changes occur and what can have an influence on your sight.Daniel Hardiman-McCartney MBE, optometrist and clinical advisor at The College of Optometrists, has explained when a person's eyesight will usually peak.

He said: "Eyesight typically reaches an adult level of vision in a person’s late teens when the eyes are fully developed, and the focusing system is most efficient. "If you need glasses for short-sightedness (myopia), this typically stabilises in the late teens to early 20s."There are many factors that can influence when our eyes start to deteriorate, but optometrist Francesca Marchetti has said that after the age of 40 some visual blurring may begin, and it can become harder to focus on objects.
