What are you using to keep little ones engaged during PD and fitting-height measurements? I’ve been using a tablet-based centration system since September and a small LED fixation light, but I’d love recommendations for a truly child-friendly pupilometer or steadier way to capture heights on 38–42 eye sizes without stressing the kiddo or compromising visual development.
pupilometer or steadier way to capture heights on 38–42 eye sizes without stressing the Skip the pupilometer — put clear tape on the demos, have them fixate a Good-Lite animal wand at about 3 m (https://www.good-lite.com), and dot pupils; transfer the marks to a ruler for heights and mono PD so 38–42 eyes are consistent without a device in their face. If your tablet does burst, snap 2–3 frames while they fixate and confirm the dots after.
Short answer from my side: I’m seeing the same pattern — one concrete thing that helped was writing down the exact handoff and timebox it to 15–20 min. Does that match what you’re running into?
I’ve had the best luck turning fixation into a prop — clip a tiny LED on a badge reel to the bridge so the light sits at vertex and cue “stare at the bug,” then trigger the tablet capture while a parent steadies the chin. Do you have someone hold the shoulder to curb the wiggles or prefer solo capture? On 38–42 eyesizes I let the tablet set PD but confirm heights by scrubbing a 5‑second phone video for neutral head, adjusting 0.5–1 mm if habitual tilt shows.
