  1. Light for Sight COTSS–Housing Conference 2010 Anthony Slater Lighting Development Manager Thomas Pocklington Trust

  2. Summary • Prevalence of sight loss • Importance of lighting • Lighting equipment • Lighting adaptations • Supporting materials and services

  3. Prevalence of sight loss • Best estimates - registerable • 13% of those aged 75+ have serious sight loss (600,000 people) • 33% of those aged 90+ have serious sight loss • Sight loss is a normal part of ageing • 13 million people in UK over 60 • Specific eye conditions can make this worse • incidence increases with age

  4. Prevalence of sight loss • Sight loss affects everyday lives of 2 million people in UK • Secondary to main reason for referral • Most people with sight loss have some residual vision • Lighting can help people to make the most of their vision

  5. Pocklington research • Findings from home visits • Low levels of lighting • Glare from light fittings • Slow adaptation to different levels • Poor control • Lack of available information / support • Assessments and adaptations to general lighting and task lighting in over 100 homes

  6. Good general and task lighting

  7. Daylight • Control with blinds • Vertical slats control direction of light entering • Net curtains can become glare source • Keep curtains clear of window • Reduce external obstructions • Keep windows clean • Light coloured sills and frames reflect light into room

  8. Improve energy efficiency • Replace incandescent tungsten filament with • Tungsten halogen • Compact fluorescent

  9. Compact fluorescent (CFL) Plug-in Globe Pear Candle Spiral Double turn Triple turn

  10. General lighting • Ceiling mounted • Diffusing shades • Even lighting • Avoid glare • Hide direct view of lamp

  11. Free-standing lighting • Uplights • Light reflected from ceiling • Task lights

  12. Task lighting • Adjustable task lights • Table or floor standing • Table clamp or heavy base • Fluorescent are cooler • Portable task lights • Rechargeable battery • Ceiling or wall mounted spotlights • Under cupboard lights

  13. Lighting adaptations • Improve general lighting levels • dimmable high frequency fluorescent in kitchen • brighter lamps (CFL) in diffusing shades • additional lights • Add task lighting • fluorescent lighting under kitchen cupboards • mirror/shaver lights in bathrooms • lighting in wardrobes and walk-in cupboards

  14. Hallway and stairs • General lighting • Good level • No glare • Reveal steps • Task lighting • Telephone • Good contrasts • Surfaces

  30. Adaptations good practice guide • Practical guidance • Adaptations • Involving people • Specific spaces • Indoors and outside • Checklists

  31. Lighting booklet • Advice on lighting • Non-technical information • Lamps and light fittings • General lighting • Task lighting • Further sources of help

  32. Lighting training • One day workshop • Lamps & fittings • Demonstrations • Practical exercises • Case studies • Design tools

  33. Specifying lighting adaptations • Determine needs • Functional vision assessment • Assess existing lighting provision • Client’s “adaptations” • Determine possible adaptations • Produce specification for electrician

  34. Some lighting options

  35. Lighting Specification Toolsnumber of lamps needed per room

  36. Lighting for sight consultancy • Existing or proposed schemes • Assessment of tenant need • Survey of existing or proposed lighting • Proposals for lighting adaptations • Improved lighting gives: • Increased independence • Decreased need for support • Reduced maintenance and running costs
