Clinical Eye-Tracking Systems for Eye Care: A Factual Comparison (October 2026)

Updated 2026-10-22

Written by the Optics Trainer team from published research, with every source linked below.

Several eye-tracking systems are now marketed to eye care clinics, and their regulatory status, hardware, published research and pricing are easy to blur together. This comparison sets out what public records and vendor sites showed when we checked them on 22 October 2026. Vendor details are stated as the vendor describes them on that date and may have changed since. It is not a ranking, and no study we found compared these systems head to head.

How we compared them

For each system we read the vendor's public product pages, searched FDA records through openFDA and the FDA 510(k) and De Novo databases, and searched Europe PMC for peer-reviewed studies. A missing openFDA record means only that none was found in those searches; it says nothing about status in other markets. Studies with different populations and reference standards cannot be compared as accuracy figures, so we report what each study measured rather than ranking accuracy.

RightEye

FDA cleared the RightEye Vision System through 510(k) K181771 on 28 September 2018, as a Class II nystagmograph (product code GWN). The cleared indication is recording, viewing and analysing eye movements in support of identifying visual tracking impairment. The 2018 summary describes software running on a Tobii Dynavox i15 all-in-one computer and states that the device does not provide a diagnosis.

As stated on the vendor site in October 2026, RightEye's Sensorimotor product is built on that FDA-cleared system and uses its VisionTracker2 hardware. The site lists named test batteries, including Sensorimotor tests (nine-point motor function, near point of convergence, cardinal gaze, 4-Dot), a Dynamic Vision module of eight pursuit, saccade, fixation and reaction-time tests, and a Reading Skills report. It does not publish prices or the current tracker's brand or sampling rate.

Several RightEye studies have company-affiliated authors, including a 2025 comparison of six RightEye tests with a neurologist's oculomotor examination in 53 people. A cohort of 88 athletes by authors not employed by RightEye (Feller and colleagues, 2021) used a RightEye protocol on a 120 Hz SMI tracker.

Thomson Clinical Eye Tracker 5L

As stated on the vendor's UK site in October 2026, the Clinical Eye Tracker 5L uses a Tobii 5L eye bar below the stimulus screen and runs on Windows. Its online manual lists reading, saccade, pursuit, cover test, phoria, fixation stability and pupillometry modules, with printable reports. The vendor gives two sampling figures: up to 120 measurements per second on the product page and about 60 per second in the manual.

Thomson publishes UK prices excluding VAT: £1,995 for the eye bar, plus software from about £32 to £35 a month, depending on the page. The manual states compliance with the UK Medical Devices Regulations 2002 and EU MDR 2017/745. We found no openFDA record for Thomson Software Solutions.

Published studies have used Thomson's software with the earlier Tobii EyeX hardware rather than the 5L, mostly in samples of 32 to 142 participants, including studies of children's reading fixations and saccades compared with NSUCO and DEM testing.

Hundred Vision Luma

Hundred Vision launched the Luma eye tracker at an online event on 8 October 2026. As stated on the vendor site that month, Luma offers seven protocols, including reading, binocular vision, digital screen and school vision analyses, and the vendor describes an age-matched normative database without giving its source or size. The site does not name the tracker or state its sampling rate, price or regulatory status. We found no peer-reviewed Luma studies and no openFDA record for Hundred Vision or Luma.

EyeBOX, for context

EyeBOX (Oculogica) is a different kind of device: a concussion assessment aid rather than an optometric eye-movement test suite, and its vendor does not list eye care clinics among its settings. FDA authorised it through De Novo DEN170091 in December 2018 as an aid in concussion diagnosis within one week of injury, for ages 5 to 67, alongside a standard neurological assessment. In its pivotal study of 282 participants, sensitivity was 80.4% and specificity 66.1%, and FDA noted that the prespecified performance goals were not met. A later study of 36 concussed and 30 non-concussed athletes aged 11 to 22 reported sensitivity of 22% to 61% and specificity of 63% to 87%, depending on the score cut-off. Oculogica has since received further FDA clearances for later models, including a handheld version, EyeBOX SNAP, cleared in June 2026 for ages 15 to 25.

What to ask any vendor

The public information differs a great deal between systems. Questions worth asking before buying include:

What is the exact FDA or CE/UKCA indication, and does it cover the hardware and software you would use?
Which tracker is used, at what sampling rate, and with what published accuracy?
Where reference or normative data are offered, how many people, of what ages, tested on which hardware?
Which peer-reviewed studies used the current hardware, and were the authors independent of the company?
What do the reports show, and can raw eye traces be reviewed?

Optics Tracker

Optics Tracker is our own product, so read this section with that in mind. Its test library includes pursuits, saccades, fixation and VOR, reaction time, reading analysis, the Developmental Eye Movement (DEM) Test™ (licensed from Bernell, an optional add-on), nine-point gaze, Worth 4 Dot and Hess testing. Reports show left and right eye traces and disparity plots. De-identified sample reports are available on this site. None of the studies or FDA records above concern Optics Tracker.

Optics Tracker is clinical decision-support software. Its results support, and do not replace, professional diagnosis and clinical judgement.

Frequently asked questions

Is RightEye FDA-cleared?

The RightEye Vision System was cleared through 510(k) K181771 in September 2018 for recording, viewing and analysing eye movements in support of identifying visual tracking impairment. Its cleared indication is visual tracking impairment rather than concussion.

Which clinical eye tracker is most accurate?

We found no head-to-head study of these systems. Published studies use different populations, hardware and reference standards, so their accuracy figures cannot be compared directly.

How much does a clinical eye tracker cost?

Of the systems compared, only Thomson published prices when we checked in October 2026: £1,995 for the Tobii 5L eye bar plus software from about £32 to £35 a month, excluding VAT. RightEye and Hundred Vision did not publish prices; RightEye describes quotes and leasing, and Hundred Vision offers demos on request.

Does Luma have published research?

We found no peer-reviewed studies of Luma as of October 2026. It launched on 8 October 2026.
