Elderly live in a care centre because of their need for nursing care. A study in The Netherlands has shown that 20% of them is blind and 22% has low vision. Care centres have poor lighting conditions. The recommended lighting level elderly need for reading (task lighting) is 1500 lux. This is only available nearby the window. Ambient lighting contributes orientation, mobility, safety and comfort. Illumination levels inside the building are average between 100-200 lux. This level needs to be at least 500 lux.
Elderly people with a lower vision have a higher need for lighting in their environment. There is a relation between a safe environment and adequate lighting and contrast. At VISIO work occupational therapists who give advice to care centres. Recommendations are given on lighting levels in the living room. Good interior lighting facilitates the performance of daily activities (ADL) of the visually impaired in their homes.
The combination of good interior lighting and regular daylight exposure contributes to regaining and maintaining an active and fulfilling lifestyle - greatly improving quality of life. The combination of poor interior lighting and low vision can lead to unsafe situations and inactivity. A building design in lighting that meets the needs of elderly with low vision increases individual's ability to perform daily activities and decrease the level of disability associated with these impairments including mobility, safety and decreases the number of fall incidents. Recommendations about good lighting and design in care centres combine several criteria including lighting level, luminance contrast, glare and colour.
By improving light conditions and luminance contrasts, residents are more challenged to come to activity and the fall risk is reduced.
Contribution to the practice of Occupational Therapy.
Optimal lighting is one of the prerequisites for performing ADL, improving quality of life.
