LIGHTING:

PARTNER IN QUALITY CARE ENVIRONMENTS

Elizabeth Brawley, AAHID, IIDA CMS/Pioneer Network Symposium April 3, 2008

SLIDE 2

Age Related Changes

Arthritis
Hypertension
Hearing Impairment
Vision Impairment
Mobility Impairment
Depression
Diabetes
Osteoporosis

SLIDE 3

Our Eyes Change As We Age

SLIDE 4

Normal Age-Related Vision Changes

Pupil is Smaller -

almost fixed in size

Less light enters

the eye

Difficult to Adjust

to Changes in Brightness

Lens Thickens -

Yellowish/Amber Color

Difficulty Focusing
Loss of Contrast

Sensitivity

SLIDE 5

Changes to the Lens

Lens of a 10 year old Lens of a 65 year old

SLIDE 6

VISION

Reduced Visual Acuity
Restricted Field of Vision
Sensitivity to Glare
Change in Depth Perception
Impaired Ability to Adapt to

Changes in Light Levels

Contrast Sensitivity
Restricted Color Recognition

SLIDE 7

Eye Diseases are More Prevalent in Older Adults

1. Macular Degeneration -

foremost cause of blindness over 60

2. Cataracts

(50% individuals ages 65-75)

3. Glaucoma
4. Diabetic Retinopathy

Implications of Age-Related Vision Loss

Increase in falls
Limits mobility in unfamiliar

areas

Limits independence

SLIDE 13

MOBILITY and FALLS

1/3 people 65+ fall each year
Half of the falls are recurrent
1 in 10 falls result in serious injury
87% of fractures in the elderly are

due to falls

SLIDE 14

Mobility: Risk Factors for Falls

Age
Vision changes
Weakness and

strength loss

Balance
Fear of falling
Cognitive loss
Incontinence
Environmental

hazards

Medication

SLIDE 15

Environmental Supports Encourage Mobility

Higher Light

Levels

Control Glare
Strong Contrast
Handrails for

Support

SLIDE 16

IMPROVE LIGHTNG

Higher Light Levels
Even Illumination
Eliminate Glare
Task Lighting
Balance Daylight and Electric Light
Combine Direct/Indirect Lighting
Provide Gradual Changes in Light Levels

ANSI/IESNA RP-28-2007 Lighting and the Visual Environment for Senior Living

ENHANCE LIGHTING

SLIDE 19

SLIDE 20

SLIDE 21

Daylighting

More natural light
Large skylights
Larger windows
Need for both skylights

and windows rather than windows alone

GARDENS AND OUTDOOR SPACES

Porches
Sunrooms
Greenhouses
Gardening
Walking &

gathering spaces

SLIDE 30

Daylight Exposure

Maintains Circadian

Rhythm

Promotes Better

Sleep Quality

Promotes Vit. D

Synthesis for Healthy Bones

Prevents

Depression

Reduces Agitation

SLIDE 31

SLEEP DISORDERS

Experienced by 50% of those over 65
72% of nursing home residents are “poor

sleepers” especially those with Alzheimer’s

Sedative and hypnotic medications are the

common treatment

These medications are strongly linked to

falls and hip fractures

Meaningful Activity

SLIDE 39

Exercise

– Increases

Mobility
Balance
Social Activity
Exposure to

Daylight

SLIDE 40

Lighting can and will make a greater difference in the success of a healthcare setting than any other single feature except for the healthcare itself.
