Securing of elderly houses in term of Elderly's vision disorders

Nowadays, the combination of the world’s population is going to getting old and this process is faster in developing countries (Gelder, 2005:215).

 One of the most common of the aging effects is loss of vision and increasing risk of different kind of vision disorder. More than 35 million of people over 45 years suffer from eye and vision disorder problems and more than two-third of adults with vision disorder consist of the elderly over 65 years. Eye is brain gate and sense of sight is the most important way of communication with around the world. The acquired information in compare of another sense is better interpreted using vision (eyesight). It may be said that in the lack of vision, information connection will be problem among another sense. The balance maintains depended on health of different senses of individuals and is one of the major reasons for elderly’s back falling. Back falling is one the major problem of threatening the health in elderly which is cause dependency (Lowlor, 2008:33), loss of quality of life and increasing of care cost. So during the secure designing for elderly, it is necessary to consider the changes and vision disorder age-related. Some of the eye diseases such as cataracts almost specific for elderly and another is more common with increasing age. Each one of eye disease of elderly affected negatively on individual’s performance and life. His adoption with environmental condition is jeopardized and its limit their lives and the interior designer is responsible so that it can provide a secure environment for elderly with accurate understanding of these impacts.

 Although, family is the best place to take care of elderly, a group of elderly excluded from the basic requirement for independent life or from sympathetic family they live in elderly houses inevitably. These people often weaker than the middle elderly and are more vulnerable. So the elderly houses can be done the most sensitive spaces for them which considering to the security of elderly is important in terms of vision disorder while designing. earlier ,some solution has present in secure design of elderly house related to vision disorder but it seem that in our society, it still does not get enough attention. So the authors of this study tried to present some solution in terms of lighting, color and signs, materials and architectural elements toward achieving to secure designing of elderly houses with focusing on architecture  based on understanding of vision disorders depending  age and its impacts on elderly performance  and finally one of the elderly houses were examined.
