The eyesight claim for candle gazing has one case report and an unfinished trial behind it — no good evidence, and eyes are a doctor’s question. The trials that finished measured dry-eye symptoms and eye pressure in glaucoma (Abraham et al., 2026; Ismail et al., 2022). The clearest results are on attention: Talwadkar et al., 2014, and Yadav et al., 2026. Twenty minutes, six days a week, eight weeks — graded as attention practice. Not medical advice.
What it says
You’ve been told staring at a candle sharpens your eyesight.
For eyesight itself I found one case report and a trial that hasn’t reported yet — no good evidence, and eyes are a doctor’s question.
The eye trials that did finish measured other things: dry-eye symptoms, and eye pressure in glaucoma — both improved against groups that didn’t gaze.
It’s best tested on attention: sixty older adults, twenty-six days of practice, better digit-span scores.
And a hundred and twenty young adults, eight weeks of it, came out with faster reaction times.
So run trāṭaka — steady gazing — as an attention drill, at the dose that trial used: twenty minutes, six days a week, for eight weeks.
That’s the Evidence Desk, where a practice and the trials testing it get graded separately.
