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.

Another study has shown people who have cataract surgery were 30 per cent les likely to develop dementia than people with cataracts who don’t.Shah explains: “There a few potential reasons why: studies show sensory impairment can lead to cognitive decline; having cataracts may lead to more social isolation, or people who have cataract surgery may be more health aware.”Cataracts develop as we age and the lens starts to work les wel.
“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.
