Book: Emotional Well-Being for the Person with Dementia

Ageing can bring changes in a person’s eyesight including the presence of cataracts, glaucoma and/or macular degeneration. As dementia progresses, there are numerous changes associated with eyesight. 

Some people with dementia have difficulties perceiving in three dimensions, some need brighter lighting, some may have reduced contrast between colours and some reduced peripheral vision.

When creating a calm, comforting space for those at end of life, sensitivities to light and sight need to be considered. Avoid placing objects in peripheral vision only. Quality and intensity of light is important. Light is known to affect the quality and quantity of sleep. An awareness that some people with dementia have hallucinations and delusions may be helpful.
