Eye Handbook is a diagnostic and treatment reference smartphone app for eye care professionals. It is the most comprehensive app specific to eyecare available on a smartphone. Recently we have added a new EHB profile, EHB directory, and EHB forums. You can now connect with eye care professionals across the world. With EHB forums, you can post pictures and ask questions in a wide variety of categories. You of course still have the ability to download videos and lectures to your smartphone. These functions are getting better and better. If you have content that you would like to contribute, please contact us at

Please feel free to contact us with any questions you may have. We are constantly striving to improve this application and welcome your feedback.

Useful pocket app

The recent update fixed the crashing issue and removed the required entry of personal info. The new interface is clean and intuitive. It has a lot of useful information and many areas that could use some filling out or clarification (the risk of summarizing complicated medical illnesses in 1 iphone screen). The bedside testing items have proven useful. Since the app has a wide intended audience, they may wish to provide an info icon on screens with some explanations -- for example, the IOL calculation and the vertex distance calculation -- I assume the first formula is SRK and I can guess what the 3 columns on the distance calculations are but titles or background would be helpful. As a free app with steady improvement, it is hard to beat.

Great Ophthalmology App

Best eye app available. Love the testing tools. Great for coding and forums. Love the calculators. A lot of information just sometimes hard to find it. Kudos.
