According to statistics released by WHO, 16.6% of the world population is suffering from vision impairment. In the
past years, many endeavours have been done to develop several devices to provide support to the visually blind and enhance the
quality of their lives by making them capable.
This paper discusses various applications being used in assistive technologies for the visually impaired. These applications focus
on using different deep learning algorithms, various sensors and text-to-speech output to the users and are available for various
platforms such as Android, iOS. The idea of writing this paper is to concisely review the recent progress of the technologies
being used in this topic and provide a clear understanding to other researchers who wish to develop further applications in this
field.
