Study 3 · Eye dominance

Which eye does the sighting, and is it always the same one?

A five-minute test of sighting dominance: the eye that keeps a target framed when you look through a small gap between your hands. It tells you the eye, how consistent it was, and whether it switched when the target was off to one side, which is what matters on a trap layout and the part the classic one-shot tests miss.

No account and nothing to install. You need a laptop or desktop with the sound on (the page speaks the cues, because both hands are busy), both hands free, a plastic card the size of a driving licence to calibrate the screen, and about an arm's length of room. At the end you can contribute the record to the study, anonymously or linked to your account if you are signed in, or just keep it.

On a phone or tablet? This test needs a laptop or desktop with a keyboard and a plastic card. Send yourself the link and come back on one.

Results so far

Evidence label: measured. It reports what your eyes did today; it makes no claim about scores and sells nothing. Independent research by Dr. Satwant Kumar, under the rules.

screen arm's length L R you, from above: close your LEFT eye
Left: the window, a small triangular gap between crossed index fingers and thumbs. Right: you from above, arms out, one eye closed, the line of sight through the gap to the disc. Ten trials at arm's length with either hand in front, three near the face.
  • What it measures: sighting dominance, its consistency across thirteen trials, and whether it changes with gaze direction, aperture distance and which hand is in front.
  • What it does not: sensory dominance, dominance strength, or anything about scores. A screen test cannot replace a coach watching your mount.
  • The gate: no individual advice (which eye to occlude, which shoulder) is drawn from a single run until a repeat session has shown the profile is repeatable; the pooled questions about cross-dominance and switching wait for a sample well beyond the first handful.
  • What is kept: only if you choose to contribute: the trials, the screen calibration, and an optional questionnaire (age band, discipline, handedness, gun shoulder, which eye you believed dominant, occluder use, corrective lenses).
