Seniors represe

41、nt the fastest growing segment of the population with over 40 million Americans over 65.1With over 10,000 Baby Boomers turning 65 everyday, ANSI/IES RP-28-07 has been expanded to include areas beyond housing and senior care facilities. New areas of interest are offices, hospital-ity, healthcare, com

42、mercial and places of assembly. The over 40 population represents approximately 89 million people and of those 63 percent have vision problems.2However, there is a prevalence of low vision in the general senior population which increases dramatically after the age of 70 (Figure 1).Figure 1: 2010 U.S

43、. Age-Specific Prevalence Rates for Low Vision by Age, and Race/Ethnicity (NEI National Eye Institute Low Vision 2010)Low Vision is defined as vision impairment that is worse than 20/60 in the better eye, which cannot be correctable medically, surgically or with conventional eye glasses.3People rely

44、 on a supportive visual environment to maximize their independence and safety. Whereas people with mobility impairments are easily identified by their use of assistive devices, i.e., wheelchairs, canes or walkers, persons with low vision do not typically use assistive devices or trail-ing techniques

45、. Sensory loss is common to the aging process; however, perception problems are not eas-ily recognized by others.As the work force ages the need for lighting guidance becomes more of a concern. It seems clear that the Baby Boomer generation (born in the years 1946 through 1964) will see aging very d

46、ifferently from their parents. They will take their current life styles and modify them slightly but will expect to continue contrib-uting to society and be visible in day-to-day life. This group will represent more than one in four Americans.Also note that according to the World Health Organization

47、, the entire world, with a few excep-tions, is aging, and governments are not prepared for the growth of seniors or how to care for them. A brief search of several industrialized countries determined that there are few regulations addressing senior vision and lighting needs and prior editions of ANS

48、I/IES RP-28-16 have been reported to be the document of choice by designers when seeking guidance in how to provide adequate light in senior communities.The IES Lighting for the Aged and Partially Sighted Committee has worked to make this current Recommended Practice document inclusive of cur-rent r

49、esearch and design practice for the above population to help them maintain a quality of life into their third age. Loss of independence has been identified as the greatest fear of aging, so todays senior will be looking for answers to maximize their aging vision.Current codes and standards are based on the needs of younger people. Steps have already been taken to begin the transition to recognizing the needs of older people. Of major importance to achieving higher lighting levels while still complying with ener-gy restraints is the adoption of ASHRAE/IES 90.1 -2013. Work by this c
