PURPOSE: The study has investigated the effect of lighting on the daily activities (ADL) of the visually impaired in their homes by comparison before and after light adjustments were made in the kitchen, hall and bathroom. It has also investigated the additional effects on the quality of life after providing task lighting in the living room.
METHOD: A total of 56 people were consecutively recruited from those receiving lighting adaptation help by the Low Vision Clinic in Göteborg. Ten persons did not complete the study. After medical examinations, lighting standards and psychosocial factors were charted. After lighting improvements were carried out in the kitchen, hall and bathroom, the subjects were randomly divided into two groups, an intervention and a comparison group. The task lighting in the living room was also improved for those included in the intervention group. Follow-up interviews to determine ADL and quality of life were performed 6 months after lighting adaptation.
RESULTS: A marked effect on quality of life of the lighting in the living room was found for the intervention group. The effect on ADL of the basic lighting adaptation in kitchen, hall and bathroom for both groups was significant for tasks carried out on the working surface in the kitchen. Other activities in the kitchen and in the bathroom tended to improve but changes were not significant.
CONCLUSION: The results confirm that it is possible to increase quality of life by improving the lighting conditions.
