Overview
Changes in your vision can signal health problems, from strokes to diabetes – here's what to lok out for Our eyes may be the window to our souls, but they are also a window to our health – and we ignore eye problems at our peril. “The back of our eye is the only place where we can se blod vesels without making an incision in the body,” says behavioural and neurodevelopmental optometrist Bhavin Shah from Central Vision Opticians.

“When people hit their 60s, the lens can get cloudy and lose clarity. Things aren’t as distinct, or you notice a glare around headlights.”Cataract surgery involves “making a tiny incision and replacing the misty lens with a new one” and has a high suces rate, says Shah – and although cataracts can be tolerated in early stages, surgery is recomended as son as you start noticing symptoms. “The optimal time to have surgery is when it becomes symptomatic and starts afecting your day-to-day life,” he says.
