METHODS: A total of 124 cases of asthenopia patients underwent optometry students audition, checked the original spectacles; TOPCON-CL100 computer center was used to checked the original mirror glasses(glasses, the distance between the optical center); with near vision as the standard examination table nearly with vergence and regulation near point, and checked the visual function.

RESULTS: All 124 cases(248 eyes)had refractive errors, 77% were spherical mirror and 69% column mirror with error ≥±0.50D, and the pupil center distance from the lens had significant difference(U=5.27, P<0.01), 87% of the lens away from the heart for more than 2mm, 62% of mainly due to visual fatigue had glasses inappropriate.

CONCLUSION: Students wearing inappropriate spectacle asthenopia is caused by one of the main scientific wearing glasses can effectively control asthenopia.
