200,000 people are living with sight loss in the capital and just under 700,000 (1 in 12 adults) are living with a sight threatening condition. Unless there are bold interventions, these figures are set to increase significantly by 2030. An estimated 50% of sight loss is avoidable, but not currently avoided. Public awareness and a stretched NHS are major contributors to these poor outcomes. The NHS recommends an eye test every two years, but over a third of people are put off eye tests due to concerns about cost and two in three parents have never taken their child for a test.
