Farnsworth D-15 with assisted scoring
Cap arrangement captured on a calibrated display. Total error score, confusion angle and axis classification returned with the raw arrangement, never instead of it.
For orthoptists, optometrists and eye care professionals
Orthoptic and optometric care, made interactive.
Screen-based tests, rehabilitation exercises and structured assessment forms for orthoptic and optometry practice, in English and French.

Orthoptic and optometry tests, online
Four capabilities in clinical use
02Motility
Hess-Weiss (Lancaster) chart
A red-green Hess and Lancaster test on any screen, up to a TV. Both eyes are charted, then read as on a printed Hess chart: primary deviation, the action of each muscle, and which field is smaller.
03Motility
Nine gaze positions, one photo sheet
One photo of the eyes in each diagnostic position of gaze, taken on a phone or tablet or imported, assembled into a single labelled sheet with the patient’s name, ready to download for the record.
Orthoptic maze, five levels
A maze traced with the finger or the mouse under a visuomotor load, from initiation to master level. Completion time and grid size are saved to the patient’s record.
New in VisReed Practice
Orthoptic assessment forms
Strabismus, neurovisual and low vision assessments to fill in during the exam, save to the patient’s record and print for signature.
Built for orthoptic and optometry practice
Every test, exercise and assessment form is designed for orthoptic and optometric examination and rehabilitation. Ophthalmologists, opticians and eye care teams use them alongside.
Binocular vision and strabismus
Cover test, motility, Hess-Weiss, vergence.
Eye movements
Saccades, pursuit, anti-saccades, nine gaze positions.
Colour vision
Farnsworth D-15 with assisted scoring.
Visual function
Accommodation, Amsler grid, reading.
Low vision and neurovision
Structured assessments and rehabilitation.

How our vision tests are built
Adaptive intelligence
Step size adapts to the responses given, shortening a test without narrowing the range it can measure.
Neural precision
Stimulus timing is bound to the display refresh, so latency measurements survive being compared between sessions.
Interactive therapy
Exercises run in the browser at home and report adherence, not scores, back to the orthoptist.
Personalised pathways
Therapy plans assembled from the tests already run, with review intervals the clinician sets and can override.
Questions about VisReed
Regulatory, data and calibration questions, answered plainly.
Who is VisReed for?
Eye care professionals. The tests and assessment forms are built for orthoptic and optometry practice, so orthoptists come first, then optometrists; ophthalmologists, opticians and other vision specialists use them too. They are for clinical use, not self-testing.
Is VisReed a certified medical device?
No. VisReed is classed as clinical decision support: it presents stimuli and records responses, and every result is returned with the raw data behind it. Diagnosis remains the clinician's. The medical disclaimer states this in full.
How is display calibration handled?
Colour and contrast tests require a profiled display. The profile is recorded with its date and luminance, stored with every result, and colour tests refuse to start without one.
Where is patient data stored?
In the European Union. Test results are held against the record only once consent is on file; without consent a result stays local and unsaved, and nothing is transmitted in the background.
Can results be exported into an existing EMR?
Results export as PDF and as structured data alongside the conditions they were recorded under. A result without its conditions is not comparable, so the two always travel together.
Which tests have published validation?
Each test carries a validated or beta badge in the library. Validated tests state their agreement with the physical instrument and the sample it was measured on.
What does it cost, and for whom?
The device index and the exercises are open. Practice accounts, which hold patient records and results over time, are for clinicians and departments.
