Effect of optical correction by fully corrected glasses on postural stability.

Area of Science:

• Optometry
• Human Physiology
• Biomechanics

Background:

• Refractive errors are known to affect postural control.
• Limited research exists on the impact of optical correction via glasses on postural stability.

Purpose of the Study:

• To investigate the effect of wearing fully corrected glasses on postural stability in individuals with myopia and hyperopia.
• To determine if optical correction enhances balance and reduces postural sway.

Main Methods:

• 34 participants (17 myopic, 17 hyperopic) underwent subjective refraction.
• Myopic participants received updated glasses; hyperopic participants received first-time glasses.
• Postural stability was assessed using the TETRAX biofeedback system, measuring postural instability and sway power indices.

Main Results:

• Wearing updated glasses for myopia correction significantly reduced the postural instability index.
• A statistically significant decrease in sway power index (mid-high frequency) was observed in myopic participants with glasses.
• No significant changes in postural instability or sway power indices were found for hyperopic participants wearing new glasses.

Conclusions:

• Optical correction of myopic refractive error positively impacts postural control and somatic functions.
• Wearing glasses to fully correct refractive errors can enhance static postural stability.
• Findings suggest clinical implications for optometry and balance assessment.
