Visual impairment in adults

Over two million people in the UK are living with sight loss, which equates to almost one person in thirty. Key statistics from the Royal National Institute of Blind People (RNIB) show:

• One in five people aged 75 and over are living with sight loss.
• One in two people aged 90 and over are living with sight loss.
• People from black and minority ethnic communities are at greater risk of some of the leading causes of sight loss.
• Adults with learning disabilities are 10 times more likely to be blind or partially sighted than the general population. 

Age-related macular degeneration is the leading cause of blindness in adults. Other significant causes of sight loss are glaucoma, cataracts and diabetic retinopathy. Sight loss affects people of all ages, but older people are more likely to experience sight loss. This number will increase due to the rise in the ageing population. Additionally, there is a growing incidence in key underlying causes of sight loss, such as obesity and diabetes. This means that, without action, the number of people with sight problems in the UK is likely to increase dramatically over the next 25 years.

Data from the RNIB tool indicate that there are an estimated 44,000 people living with some degree of sight loss in Lancashire-12. Of these 38,130 are living with partial sight and 5,920 are living with blindness (2022). By 2032 there are expected to be 53,200 people in Lancashire living with sight loss, an increase of 21% from 2022.

The PANSI website provides estimates of visual impairment down to lower tier local authority level for several different adult age bandings. The latest estimates show that there are predicted to be over 24,000 adults (aged 18+) in Lancashire-12 with a moderate or serious visual impairment.
