因不同的眼部和神经性疾病，导致视觉功能严重受损，为低视力患者日常活动(如阅读及驾驶)及生活质量、心理健康带来严重的影响。人们对外界信息的感知主要来源于视觉，除威胁生命的重大疾病外，对人感官影响最大的损害当属视觉损伤。且随着人口日益老龄化，该问题日趋加重，低视力已成为目前全球范围内一个严重的公共卫生问题。目前，低视力康复发展面临着临床和科研的巨大挑战，要研发出一种能有效改善视觉功能，同时能兼顾多种功能的视障辅助技术，这需要医学、生物学、工程学、微电子学、计算机学等多学科的共同发展和相互合作。低视力康复通过为患者提供适宜的视障辅助技术，最大化利用患者的残余视力及视觉功能，改善与低视力相关的功能限制，有效改善其独立性和整体生活质量，使其独立生活、工作并融入社会成为可能。该文对经典的助视器、人工视觉(视觉假体/视觉感官替代设备)、经颅刺激及视觉生物反馈训练等视障辅助技术在低视力康复中的应用进展进行综述。

Patients with low vision are severely impaired in visual function due to different ocular and neurological disorders,which have a serious impact on their daily activities (such as reading and driving), quality of life and mental health.People's perception of external information mainly comes from vision. Expect for the life-threatening major diseases,visual damage has the greatest impact on people's senses. With the ageing of the population, the problem is getting worse, and low vision has become a serious public health problem in the world. Currently the development of low vision rehabilitation is facing a huge challenge in clinical and scientific research, to develop a visual impairment assistance technology that can effectively improve visual function while balancing multiple functions. It requires the joint development and cooperation of multiple disciplines such as medicine, biology, engineering, microelectronics, and computer science. Low vision rehabilitation provides patients with appropriate visual impairment assistance technology,maximizing the use of residual vision and visual function of patients, improving the functional limitations associated with low vision, effectively improving their independence and overall quality of life, and makes it possible for them to live, work and integrate into the society independently. This article reviews the progress in the application on visual impaired assistive technologies such as classic visual aids, artificial vision (visual prostheses/visual sensory replacement devices), transcranial stimulation and visual biofeedback training in low vision rehabilitation.
