Researchers from Pakistan recently published an article about an app that is leading people affected by night blindness. According to Wikipedia …

Nyctalopia (from Greek νύκτ-, nykt- “night”; and αλαός, alaos “blindness”) also called “Night Blindness” is a condition making it difficult or impossible to see in relatively low light. It is a symptom of several eye diseases. Night blindness may exist from birth, or be caused by injury or malnutrition (for example, a lack of vitamin A). It can be described as insufficient adaptation to darkness. […](link to wikipedia)

The article by Kamran Ahsan, Obaid Khanand and Abdul Salamon on “Assistive technology for night blindness: a mobile application approach” was published in the Int. J. of Mobile Learning and Organisation, 2013 Vol.7, No.2, pp.140 – 157. Here is the abstract:

Night blindness is one of the commonly observed problems of the eyes around the world. The night blindness is estimated to affect 5.2 million preschool-age children. The increase in the night-blind population around the world demands technology assistance to those people for avoiding darkness. Lots of efforts so far have been put up by researchers to address different health issues with several mobile applications for providing assistance to affected people. The mobile application model to assist night-blind person is still one of the unaddressed issues by researchers. In this paper, we propose a mobile application model for night-blind persons to avoid them from travelling in darkness. The proposed application model is based on the difference of current time and sunset time. The proposed application uses difference of time function to proactively alert the night-blind person to reach safer place or destination before sunset. The application is useful for avoiding darkness.
