Key Statistics

There are almost 2 million people in the UK living with with sight loss (Access Economics, 2009).  Sight loss affects people of all ages but especially older people:

  • 1 in 5 people aged 75 and 1 in 2 aged 90+ are living with sight loss (Access Economics, 2009). 
  • Nearly half of blind or partially sighted people feel ‘moderately’ or ‘completely’ cut off from people and things around them (Nzegwu and Dooley, 2006).
  • Around 96500 adults with learning disabilities are blind or partially sighted (Emerson and Robertson, 2011).

 

Vision and Dementia

People with dementia may experience problems with their sight which can cause them to misinterpret the world around them. Problems that involve vision and perception can be referred to as VISUOPERCEPTIVE DIFFICULTIES. These problems include:

  •  Illusions - person sees a distortion of reality, usually caused by low contrast or patterned objects. eg: seeing a face in a patterned curtain
  • Misperceptions - what a person sees is a best guess, usually exacerbated by blur caused by eye disease. eg: a shadow on a carpet may look like a hole
  • Misidentifications - when certain parts of the brain become damaged it can lead to problems identifying objects and people. eg distinguishing son and husband

 

These problems can be reduced by considering the colours, contrast levels, use of patterns, lighting reflective properties of objects and information in the living environment. This information has been fundamental in the design process of our signage.
