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

Not very useful

Poor reference for eye emergencies.

Not impressed on iPad

I'm an O.D. I got this ap because I thought it would be an easy way to browse all the journals in one place and maybe brush up on some conditions I don't see too often. I guess it's not meant for iPad because you have to magnify from iphone size to fill the screen, which makes the print look faded and blurry. Also it doesn't respond to tilting the iPad for landscape. You can't pinch to zoom or expand, all of which makes it impossible to read a journal article comfortably.
I was hoping for nice images of conditions, but they are not hi res and there's only one pic per disease, and it's not at all comprehensive as far as number of conditions mentioned. I was also hoping for something I could show to a patient in explaining common conditions, but even the description of blepharitis or dry eye is too incomplete to be of any use.
The resolution is even too bad to use the near point cards, and I couldn't get the Ishihara color vision test to show the actual testing cards. It only shows the example plate with the 12 but won't go on to the rest.
I'm giving it two stars only because it might be of use for someone starting to work in the eye care field as a tech or optician wanting to learn just basics.

Great for neurologists too

I must say, this may be one of if not the best program I have used on my iPhone. It is very useful. As a neurologist I find it very helpful especially okn tape among other features. I think you would be well served to group together some functions for neuro-opth. Then you could market this to neurologists too. Have a red screen to test for color desaturation for optic neuritis. Also maybe some other functions would be good as well whenever it's updated next. Lastly I would recommend making the app less than 10mb if possible. That way more ppl would be willing to try it. The main program could be same size, but maybe pick and choose functions to keep size down. Having to only use wifi is a deterrent in trying an app. Thanks again.
