Online or distance education, simply, is the teaching and learning process done via different online medium be it audio conference, video conference, articles, etc. Its history goes way back to 1982 when Western Behavioral Sciences Institute, California exercised computer conferencing to provide first ever online college programs. Later on, along with the development in technology and internet browsers, online education via video and audio conferences, videos, websites and articles evolved.
Various universities and colleges throughout the world have been offering online education in one form or another for a long time. Even though distance learning was introduced decades ago, it popularized largely after the entire world underwent lockdown due to the fear of contagious spread of COVID-19, a lethal virus, and students had to study from home.
After pandemic, the online education system replaced the traditional educational system. The imposition of lockdown prohibited people from going out except for urgent cases; so, physical educational system were replaced by online system. Classes, assignments, lectures, discussions, projects, research, examinations and everything had to be done and submitted online; as a result, the use of electronic gadgets like Smartphone, tablet, laptop, desktop, etc. escalated. People from all around the world, especially students, teachers and workers, had an increase in their screentime be it in smartphones or laptops or desktop. The usage of e-gadgets surged along with people's dependency on it for official and personal purpose.
Along with the use of electronic gadgets, the use of various video-conferencing applications like Zoom, Google Meet, etc. on which the classes were conducted increased by more than ten times.
However, experts believe that increase in screen time of students from an elementary level child to an university level student may lead to various health related problems. Some of the major health issues that have resulted are eye strain, technostress, frustration, dullness, etc. Thereupon, they have suggested students to try and reduce their screentime as much as possible and try to engage themselves in something non-digital.
