Diffractive optical element (D.O.E) spectacle lenses for myopia prevention and control: a small-scale pilot study among younger Chinese children.

D. O. E spectacle lenses used in this pilot study demonstrated a statistically significant, though not clinically meaningful, effect in slowing myopia progression among younger Chinese children.

The primary limitations were the small sample size and the short observation period, which restricted the ability to detect clinically significant changes.

These findings are preliminary and require further validation before they can inform clinical decision-making.
