Mobile Apps & Resources: Eye Handbook


To keep you updated on the go, our ‘app of the month’ highlights one free informational app every month!

Librarian reviewers consider the audience and purpose of the apps, as well as highlighting additional features:
  • In the ‘Evidence’ section, we assess how easily an app user can identify the app’s currency and support from the evidence
  • In the ‘Usability’ section, we assess the organization of information and other usability factors that may contribute to user experience

Our complete grading criteria for evidence and usability are embedded in the review.

Please note that the reviewers are not healthcare professionals, and so cannot appraise the quality of any recommendations within the app. The reviews are not endorsements.

Part 1: Editorial committee, content updates, and evidence grading

Information relating to the editorial committee is found within the app. As part of this, the Chief Editors are listed, along with Lead Editors for several specialty areas. There does not appear to be a grading system used within the app, and no information has been provided relating to content updates.

Part 2: Source and authorship information for 3 entries

The fact that this app describes itself as a reference tool is not as strongly backed up by authorship or evidence provision throughout the app as it could be, unfortunately.

The provision of authorship information within this App is inconsistent and is reflected in the low scoring given. With regards to this, authorship was not provided for all EHB Manual entries. References were included for all three entries, but in some cases the evidence appeared to be dated; the lack of clarity around the update frequency of the content within the app is unfortunate. The links to external evidence were live and it was possible to access the articles within the app. However this feature only worked within the iPhone version of the app; it was not possible to open the article links within the Android version of the app, as part of the review. It appeared the currency of evidence being provided varied between entries. The video entry that was reviewed was lacking in the provision of evidence.

Organization of information

The information is organized using three separate navigation menus. Several topics within the navigation menus also use sub-topics to display more focused, subject-specific information.


The first navigation menu is represented by 3 lines and can be found on the topic left hand side of the app –this menu brings you to settings, info about the app and the login area. The second navigation option is visual in nature and is represented by icons – these icons provide access to the EHB Manual and Testing information, for example. The third navigation menu can be found at the bottom of the screen – this provides access to News, the user directory and a Reference tool, for example. It is also possible to search the Reference tool using keywords.
