As we mark Dementia Action Week, it’s vital to shine a light on an often-overlooked issue: the high rate of undiagnosed sight loss among people living with dementia.
Sight plays a key role in how we understand, interpret, and interact with the world — something that becomes even more critical for people already facing cognitive challenges.
A Hidden Problem: Undiagnosed Sight Loss
Research shows that 1/3 of people living with dementia also have some form of sight loss (RNIB PrOVIDe study 2016). A large number of these cases remain undiagnosed, compounding the difficulties they face with communication, memory, mobility, and daily tasks.
Sight loss in someone with dementia can easily be mistaken for cognitive decline, leading to misunderstandings or incorrect assumptions about their abilities. But with the right support and timely eye care, many visual problems can be improved — and quality of life significantly enhanced.
Why Eye Tests Still Matter
People with dementia can and should have regular eye tests, just like anyone else. In fact, the earlier problems are detected, the better the outcomes — whether it’s updating glasses, treating cataracts, or identifying other conditions like glaucoma.
Regular eye exams can:
Improve confidence and independence
Reduce the risk of falls
Help maintain hobbies and daily activities
Make communication and facial recognition easier
Support better mental and emotional wellbeing
According to the College of Optometrists, 1 in 5 people over the age of 75 are living with some degree of sight loss — and the majority of people with dementia fall into this age group.
Making Eye Care Accessible
At Berkshire Vision, we understand the importance of accessible and dementia-friendly eye care. That’s why we encourage families, carers, and professionals to ensure regular vision checks are part of routine care planning.
Simple adjustments — like using familiar environments, giving clear instructions, and offering reassurance — can make a big difference in supporting someone with dementia through an eye exam.
Small Steps, Big Impact
This Dementia Action Week, we’re asking everyone to consider:
📅 When was the last time your loved one with dementia had their eyes checked?
Taking this small step can lead to life-changing improvements in comfort, safety, and independence.
