In 2017, UNESCO launched the International Day of Light to promote international cooperation in key areas of modern science. This day is intended to strengthen policy and management in the field of science, technology and innovation, as well as the interaction between science, politics and society. International Day of Light aims to build institutional capacity in science and engineering, using the role of scientific cooperation to achieve peace and sustainable development.

 Light plays a central role in human activity. At the most fundamental level, through photosynthesis, light is the source of the origin of life itself. Numerous uses of light in medicine, communications, the entertainment industry and in culture have revolutionized society. Light-based industries are the main engines of economic growth, and light-related technologies directly meet the needs of humanity. They are increasingly used in solving global problems, in particular, in the field of energy, education, agriculture and community health. Since light is becoming a key interdisciplinary area of ​​science and engineering, it is important to fully understand the importance of scientific research on light and the application of technologies based on it. It is equally necessary that the scientific and engineering career in this field continue to attract the most talented young minds.

International Day of Light is celebrated annually on May 16, on the anniversary of the first successful use of a laser in 1960, developed by the physicist and engineer Theodor Maiman. This day is a call to strengthen scientific cooperation and use its potential to promote peace and sustainable development.
“Access to light and energy infrastructure helps to ensure a higher quality of life in developing countries, and the use of fiber optic technologies makes it possible to connect citizens of the whole world through the Internet. Such networking, among other things, creates the conditions for greater accountability in ensuring peace, justice and the effective functioning of legal institutions. ”
