Objective To evaluate the rehabilitation of children with different levels of visual impairment involving both distance vision and near vision and to discuss the range of rehabilitation achieved with vision aids. Methods Two hundred and six children aged 4 -14 years from the Guangzhou school for the blind and low vision clinic were grouped according to levels of visual impairment. Distance vision and reading rate performance were compared using a domestic 4X or 6X telescope for distance vision rehabilitation glasses and simple electronic devices. Results were analyzed with rank sum test or chi -square test. Results The improvement in visual acuity was statistically significant for children with visual impairment before and after the use of ordinary optical vision aids in the FC/10 cm to <0.05 group (P=0.0034) and the 0.05 to <0.3 group (P<0.01). The differences in the reading performance rate in the light perception to <0.05 group and low vision group between near-vision aids and simple electronic vision aids were both statistically significant (P<0.01). The success rate with simple electronic vision aids was much higher than that with optical vision aids. Conclusion The range of rehabilitation for children with visual impairment can extend to 0.01 or even less. Vision aids for children with visual disability are very effective and necessary. Early visual rehabilitation, especially with the use of simple electronic devices, can improve the children's learning ability. It is critical for their growth and their return to society.
