Prevalence of sight loss
l Best estimates – 13% of those aged 75+ have serious sight loss
– 33% of those aged 90+ have serious sight loss
l Sight loss is a normal part of ageing – 14 million people in UK over 60
l Specific eye conditions can make this worse – incidence increases with age

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

Pocklington research
l Findings from home visits
– Low levels of lighting
– Glare from light fittings
– Slow adaptation to different levels
– Poor control
– Lack of available information / support
