Purpose: The purpose of this study was to investigate the effect of wearing plus lens on reading ability in college students with normal binocular function.

Methods: Accommodative lag and reading ability were measured in 42 college students with normal binocular function, and no eye disease. For the control lag test the subjective cross cylinder method was applied, and for the reading ability the duration of fixation, number of regression, saccadic in return sweep and reading rate were measured using the
Readalyzer. The subjects reading abilities were measured before and after with the plus lens corresponding to the amount of accommodative lag. Statistical analysis using SPSS version 21.0(SPSS Inc, Chicago, IL, USA) was used to analyze the change of the ability before and after wearing the plus lens through a paired t-test.

Results: When the subjects wore the plus lens corresponding to the accommodative lag, the duration of fixation was slightly increased, the number of regression was significantly decreased, and the reading rate was significantly increased.

Conclusion: It was considered that wearing plus lens with low refractive power may affect the time to look at words during reading. During reading with the lens, it may also have an effect changes such as reducing the number of regression and increasing the reading rate.
