Purpose : To evaluate the clinical value of a portable monocular sight aid. METHODS: A total of 2.5 new portable 2.5-fold portable monoculars developed by our country were used in 66 patients (12 2 eyes) with blindness and low vision. Their visual function was greatly improved, and their visual acuity was improved significantly. RESULTS: A total of 24 eyes had visual acuity ≥ 0 . 0 5 after using a monocular telescope. The occlusive rate was 96 %. In 91 eyes with low vision, 75 eyes had a visual acuity ≥ 0.3 and the disability rate was 82. .4%. Conclusion: The telescope is a necessary device for low-vision clinics, and it is also the only visual aid with low visual acuity. China’s successful portable 2.5-fold monocular telescope is not only reliable, superior quality, exquisite craftsmanship, easy to use, and inexpensive
