Naked-Eye 3-Dimensional Vision Training for Myopia Control: A Randomized Clinical Trial

Area of Science:

• Ophthalmology
• Pediatric Optometry
• Clinical Trials

Background:

• Early-onset myopia increases the risk of high myopia, potentially leading to irreversible vision loss.
• Effective myopia control strategies are crucial for preventing severe visual impairment in children.

Purpose of the Study:

• To evaluate the efficacy and safety of naked-eye 3-dimensional vision training (NVT) in preventing myopia progression among children.
• To assess the impact of NVT on axial length and spherical equivalent refraction.

Main Methods:

• A randomized clinical trial involving 263 children aged 6-18 years with myopia.
• The intervention group received daily 20-minute NVT sessions, while the control group received no vision training.
• Primary outcome measured was the change in axial length at 6 months; spherical equivalent refraction was a secondary outcome.

Main Results:

• The NVT group showed a smaller increase in axial length (0.18 mm) compared to the control group (0.23 mm), a statistically significant difference (P < .001).
• The intervention also resulted in a significantly smaller myopic shift in spherical equivalent refraction (-0.25 D vs. -0.35 D, P = .02).
• No adverse reactions were reported in the NVT group during the study period.

Conclusions:

• Naked-eye 3-dimensional vision training (NVT) is a safe and effective method for controlling myopia progression in children.
• NVT demonstrates potential as a promising intervention for pediatric myopia management, with good patient adherence observed.
