Purpose:
To evaluate the reading speed of adolescents with different causes of low vision using electronic visual aids.
Methods:
The screening of 10 young students from Quanzhou Blind School could read Chinese N5 print by different optical aids. After their refractive correction and ophthalmic examination, the reading speeds with Chinese N5 print were measured using various optical and electronic visual aids.
Results:
The reading speed of (34.36±5.06) word / min by electronic visual aids performed faster than that of (18.50±6.54) word / min by optical visual aids in 10 young students with low vision (P<0.05). The reading speed of young people with low vision due to different causes had no direct linear correlation with their near visual acuity（P>0.05）.
Conclusion:
The electronic visual aids more significantly improve the reading speed of young people with low vision than the optical visual aids did. The reading speed of young people with low vision is not relevant to their near visual acuity induced by different causes.
