Abstract Objective To study the impact of distance myoporthosis spectacles on reading position among myopic children. Methods A cross-sectional survey of 148 cases was carried out. Children with refractive errors between -0.50 and -6.50 D and astigmatism less than -0.75 D were involved in the study. We recorded the reading posture of children by using a camera and measured head and eye movement patterns under near reading conditions for both uncorrected and corrected conditions. The effect of correction and no correction on the above patterns was also investigated. Data were analyzed using paired t test and Pearson correlation. Results ?譹?訛Uncorrected myopia influenced reading position, that is, head and eye positions. Refractive correcting spectacles can reduce both the scope of head movement (t=10.661, P<0.01) and eye movement (t=-4.079, P<0.01); ?譺?訛Since eyes and lenses are non-coaxial and away from the optical center, spectacles for distance do not adapt to the change in eye position while reading. Conclusion Spectacles for distance can help myopic children correct their reading position to a certain extent but cannot fully meet the requirements of reading.
