What does the Online Sleep Survey involve?

The purpose of the survey is to identify any sleep concerns and disruption to daily rhythms that may be experienced by visually impaired individuals.

The outcomes of this research will help us to provide informed feedback to healthcare professionals about the links between sleep and vision loss, and guide further research to meet the needs of the community.

The Online Survey will ask you questions related to your:

  • Visual health
  • Sleep
  • Physical health and current medications
  • Mental health and well-being
  • Light perception and any associated pain or discomfort

The Survey takes 45 – 60 minutes to complete and can be completed online, or over the telephone with one of our friendly researchers.

The survey is open to adults over the age of 18 who live in the UK and who are registered as sight impaired or severely sight impaired.
