Poor eyesight is worsening dementia symptoms for people in Lincoln

Undiagnosed sight problems could be worsening symptoms for people living with dementia, eye health experts have warned, with changes in vision often mistaken as part of the condition itself.

During Dementia Awareness Week (18–24 May 2026), Dr Stephen Hannan from Optical Express is urging families and caregivers to take changes in eyesight seriously, particularly in older adults experiencing memory loss or confusion.

Research increasingly shows a strong link between vision impairment and dementia risk, with studies suggesting untreated eye conditions such as cataracts may contribute to cognitive decline.

For people already living with dementia, poor eyesight can make symptoms significantly worse. Reduced vision may increase disorientation, heighten anxiety, affect communication, and make everyday activities such as reading, recognising faces, navigating stairs or moving safely around the home far more difficult.

Experts say many visual problems remain undiagnosed because symptoms are often incorrectly attributed to ageing or dementia itself.

Eye examinations can identify treatable conditions including cataracts, glaucoma and age-related macular degeneration — all of which can have a major impact on quality of life if left untreated.

Recent studies have also found that people with cataracts who undergo cataract surgery may have a lower risk of developing dementia compared with those whose cataracts remain untreated.

Dr Stephen Hannan, Clinical Services Director at Optical Express, said: “People living with dementia already face daily challenges, and unrecognised vision problems can make those difficulties even greater.

“We often see patients whose confidence, mobility and overall wellbeing improve dramatically once an underlying eyesight problem is identified and treated.

“Clear vision plays an important role in helping people maintain independence, stay socially connected and safely carry out everyday tasks.

“There is also growing evidence linking untreated sight problems, particularly cataracts, with an increased risk of cognitive decline. While more research is ongoing, protecting eye health is increasingly being recognised as an important part of supporting long-term brain health.”
