Lighting design features of old soft welfare facilities

With the increase of age, transparent lens, cornea tissue will increase in turbidity, eye astigmatism, through reduced performance. Older people are more sensitive to glare, due to the arrival of the retina, the ability to identify the color difference, the ability to distinguish between light and shade have declined. The lighting design of the welfare facilities for the elderly should take full account of these visual characteristics. General illumination is high, vision will be improved, the premise is not only to improve the design of lighting than the general facilities, but also must control the glare and the difference in the illumination of each part.

On the other hand, with the increase of body function and reduce the ridge, not only limited to the visual function, including sleep reduction (circadian rhythm weakened), increased urination reduced these functions. Elderly welfare facilities, the need to consider the decline in the quality of sleep at night, irregular, abnormal actions such as walking around the night caused by the accident is not too clear and fall accidents. In order to improve these problems, the rhythm of the circadian clock is stable, and the use of high illumination light during the day has become an effective way to take care of the elderly.

As mentioned above, the visual and physiological functions of the elderly should be taken into account in the lighting design of the elderly welfare facilities.
