Home lighting assessment for clients with low vision.

Area of Science:

• Ophthalmology
• Gerontology
• Rehabilitation Science

Background:

• Older adults with low vision often face challenges with home lighting during near tasks.
• Objective and comprehensive assessments are needed to guide lighting interventions.

Purpose of the Study:

• To develop and validate an objective, comprehensive, near-task home lighting assessment for older adults with low vision.
• To evaluate the reliability and clinical utility of the developed assessment tool.

Main Methods:

• A home lighting assessment tool, the Home Environment Lighting Assessment (HELA), was created.
• Interrater and test-retest reliability studies were conducted with older adults with low vision.
• Clinical utility was assessed by occupational therapists specializing in low vision rehabilitation.

Main Results:

• High interrater reliability (intraclass correlation coefficient [ICC] = .83-1.0) was achieved.
• Moderate test-retest reliability (ICC = .67) was observed.
• The HELA demonstrated strong clinical utility based on feedback from occupational therapists.

Conclusions:

• The HELA is a structured tool for assessing quantitative and qualitative aspects of home lighting for near tasks.
• It can guide lighting intervention planning for individuals with low vision.
• The HELA has the potential to enhance assessment and intervention practices for rehabilitation professionals and improve near-task performance in older adults with low vision.
