Welcome to the Survey of Health and Sleep in the Visually Impaired. On this site you will be asked a series of screening questions to determine your eligibility for the study. You will be asked to agree to a consent form describing the study procedures and you will also be prompted to take the survey portion of the study on the web. We prefer that you complete the survey in one sitting, though we understand that occasionally this may not be possible. Following consent, you will be asked to complete a registration form containing your e-mail address. Once this form is submitted, an e-mail containing a unique username and password will be sent to the e-mail address you provided. The username and password will allow you to re-access your survey if you are not able to take it in one sitting. We hope this will allow flexibility for all respondents. To ensure consistency within your responses, we ask that you complete the entire survey within 48 hours. Please continue with this registration process only if you wish to complete everything on the web. If you prefer to take the survey in Braille, large print, on audio cassette, on a CD, or by e-mail, please do not enter any information on this site; instead, please e-mail Erin at bvihealthsurvey@rics.bwh.harvard.edu or call her at 1-888-8BVI-BWH (1-888-828-4294). Erin will provide you with the consent form and all of the survey materials in the format of your choice.

Survey of Health and Sleep in the Visually Impaired Web Screening Form

Thank you for expressing an interest in our “Survey of Health and Sleep in the Visually Impaired.” The purpose of the study is to survey health and sleep in visually impaired people. Previous studies have suggested that certain health outcomes are different in blind people compared to the sighted population, for example, incidence of sleep disorders, reproductive function and cancer risk. This study aims to test some of these previous findings in a large survey of visually impaired people to try to determine whether hormones related to light exposure and sleep are responsible for differences breast cancer risk. The results may help to identify risk factors associated with certain medical disorders and help people make more informed lifestyle choices.

We only wish to study people who are legally blind
