Objective  To evaluate the effect of refraction and visual rehabilitation on students in schools for the blind in Zhejiang province. Methods  In this cross-sectional investigation， 219 students in 3 schools for the blind in Zhejiang province were included. The students underwent eye examinations， visual acuity tests， refractive correction and low vision rehabilitation. Results were analyzed with a paired t test. Results  The differences in visual acuity were significant after refraction （3.53±0.34 vs. 3.85±0.27， t=-14.997， P＜0.01）. The BCVA of 153 patients <3.7， and 66 patients ≥3.7. The differences in visual acuity were also significant after using a telescopic device （2.03±0.94 vs. 2.12±1.06， t=-5.537， P＜0.01） for blind patients and for low vision patients （3.90±0.23 vs. 4.55±0.24， t=-28.537， P＜0.01）. After using a telescope， distance visual acuity was ≥3.7 in 24% of blind children and was ≥4.5 for 80% of low vision children. Conclusion  Refraction and low vision aids can improve students′ visual acuity which is important to further their education.
