OptOK: a universal toolkit for eye examination
OptOK is an eye examination toolkit that includes:
* Snellen visual acuity
* Jaeger-style reading tests (the ONLY app to offer this!)
* optokinetic nystagmus
"I use OptOK to test acuity in virtually every patient. It's quick, accurate and really impresses medical students!" - A UK Neurologist
OptOK is designed by professionals, for professionals at an unbeatably low price.
* landscape and portrait support
* more features than other, more expensive, optical test suites
* retina display support
* fully customisable acuity tests
* custom speed optokinetic nystagmus test
* measure acuity at any distance from 60cm/24in to 7m/24ft
* comprehensive range of optotypes (Snellen letters, Ladolt Cs or Tumbling Es)
* metric or US distances
* US, British and ISO acuity scales
* UNIQUE sweep-to-progress interface saves time and is easier for the patient
* UNIQUE shake-to-shuffle feature to double check the acuity or switch rapidly from one eye to the other
Test visual acuity using your iPhone or iPod Touch. Choose the optotype, distance and acuity scale from a wide selection. Then swipe through the screens to progress to the next acuity – a tap of the screen shows you the result in a variety of formats. A quick shake of the device refreshes the current test to verify the result - and impress colleagues and patients!
OptOK's UNIQUE reading test presents the patient with a variety of texts written in simple English at a range of sizes. Reading is the function most patients list as their primary objective when going for an eye test. It also tests a larger retinal area than letter reading, so complements acuity testing. Swipe through the sizes, shake to refresh the text and tap to see the results in both U.S. Style M units and British/Australian N units.
OptOK's nystagmus test is a simple, convenient replacement for cumbersome drums or tapes used to test for optokinetic nystagmus (the optokinetic reflex). Simply swipe your finger to set the stripes moving at the desired speed then look for nystagmus (jerking eye movements). Stop the movement by simply tapping. Optokinetic nystagmus is a normal reflex, so patients with functional blindness will have preserved OKN. Nystagmus that persists once the moving stimulus is stopped may be abnormal.
OptOK is an essential tool for optometrists, opticians, ophthalmologists, neurologists, ENT surgeons (otorhinolaryngologists) and medical students as well as anyone interested in the workings of the brain.
This app should not be relied upon to make clinical decisions, which remain the full responsibility of the user. Consult a doctor if you are experiencing neurological symptoms.

Great eye testing tool
Please all parents that think that your child has problems with their eyes but passes all school exams. This app. Is essential for you and your child. Our son passed all school eye testing, took him to a hearing specialist, which he passed. We could not understand why he would tilt his head while watching T.V. Or trying to focus on something. When he started to get really bad headaches and said he was seeing lightning flashes, that's when we finally went to a optometrist. He was finally diagnosed with nystagmus. We now are taking him to visual therapy every week. If we would of found this out when he was younger... It could have been corrected! Thanks for listening! ;)
The "start" button doesn't appear on the acuity test setup, so it's unusable. I would like a refund, please.
