People with visual impairments
Vision declines with age. This often causes uncertainty and confusion for those affected. Colour vision is also important for our mind and contributes to a natural zest for life.
Visual impairment Due to the addition of various visual impairments, the intensity of colours is perceived less strongly in old age. In poor lighting conditions and with deteriorating eyesight, the eye distinguishes less between hues and saturation and more between light and dark contrasts. Blue deficiency In older people, the visual sensitivity in the biologically particularly effective wavelength 430 nm (blue colour) is reduced by approx. 80 % compared to young people. The short-wave light components only reach the retina to a limited extent due to lens opacity. The colour blue is therefore usually perceived as greyish in old age. To counteract this, more intensive colours should be used. In this way, colours return to the world of the elderly. Their zest for life is increased, which in turn has a positive effect on their health and well-being. Create contrasts As mentioned above, the eye primarily distinguishes light-dark contrasts due to declining eyesight. Through the correct use of light and the conscious selection of high-contrast surfaces, it is possible to create visual accessibility for residents.
Because of these limitations, it is important to consider the following in interior design with regard to lighting, colour design and choice of materials:
WHO LIVES IN A NURSING HOME? Mental, cognitive and physical abilities are lost over years by those suffering from dementia. Complex actions can usually no longer be grasped due to the loss of short-term memory. Long-term memory, on the other hand, remains intact for a long time. Memories of the past are still possible for many de - mentia patients, but what has just happened is no longer present. This leads to an increased sense of stress, which can be reduced by an adapted room situation. People with dementia
• stimulating and contrasting interior design with light, colour and materials • strong brightness contrasts for improved perception • well-dosed use of strong colours and contrasts • colour and material accents through textiles and furnishings
Therefore, the following should be considered when furnishing rooms for dementia patients:
• avoid overstimulation • integrate old familiar things into the room situation / offer links to the past
• create sensory stimuli • create clarity and order • create orientation and emotional security • provide a safe living environment • dampening acoustics through sound-absorbing materials

The targeted use of calm colours, moderate patterns objects from the past and sound-absorbing materials helps to create a relaxed and safe environment for people with dementia.
