A 2009 study on the effects of education intervention on health information literacy in low socioeconomic senior citizens explored how information literacy training could improve their online searching skills. The study explained that physical, hearing, and visual impairments, which often increase with age, were some of the barriers to many senior citizens attempting online searches for health information.

The NIH SeniorHealth web site (http://nihseniorhealth.gov/) is a prime example of web accessibility. Though the website has colorful images, they are presented in a very uncluttered manner. Not only can the text be magnified, but contrast can also be set to create a black background with yellow writing. Speech can also be turned on to have all text read aloud within the browser. Information is arranged in an easy-to-navigate manner and all text is an easy-to-read level of comprehension.
