Purpose: This study aimed to prove whether wearing full-corrected new glasses had a positive effect on postural stability.
Methods: Thirty-six young subjects (21 males and 15 females) with an average age of 22.39±2.30 years participated in this study. After measuring the correcting powers of refractive errors of subjects through subjective refraction, full-corrected new glasses were provided to 19 myopic and 17 hyperopic patients. Postural evaluation was carried out using the TETRAX system, we compared and analyzed the general stability (ST) index before and after wearing full corrected glasses and their timedependent changes.
Results: When full-corrected new glasses were worn, ST indices were significantly decreased compared to those in the no glasses state in all 36 subjects (p<0.05). In the myopic group, ST indices were significantly decreased compared to those in the no glasses state when full-corrected new glasses were worn (p<0.05). On the other hand, in the hyperopic group, there was no statistically significant difference after wearing new glasses (p>0.05). Time-dependent change in ST index significantly decreased immediately after wearing full-corrected new glasses (p<0.01), and decreased more remarkably after 6 h of wearing (p<0.01).
Conclusions: Through this study, it was demonstrated that the appropriate visual information by the actual optical correction has a positive effect in increasing the posture control ability.
