Improving the research equipment system to study the impact of artificial lighting environments on human vision and health.

A national-level science and technology project led by the Institute of Materials Science has successfully developed a specialized equipment system for researching the impact of artificial lighting environments on the visual system. The research results provide a scientific basis for optimizing lighting, supporting vision, and protecting the eyes in the context of increasing demand for artificial lighting.

The project "Designing and fabricating a specialized equipment system to study the impact of artificial lighting environments on the human visual system; proposing lighting solutions to support vision and protect human eyes" was implemented from January 2023 to December 2025, carried out by Dr. Duong Thi Giang and the research team of the Institute of Materials Science .

To date, the project has identified the impacts of artificial lighting on visual acuity and compared them to natural lighting. It has also established the first scientific basis and research equipment system in Vietnam capable of simultaneously measuring pupil size and visual acuity under multivariate light control conditions. This system allows for accurate assessment of the correlation between lighting parameters, pupillary reflexes, and visual acuity, contributing to the optimization of artificial lighting to protect the eyes and improve visual performance.

The project involved designing two systems for studying the environmental impact of artificial lighting on vision, including the design and manufacturing process of the equipment, scientific reports on the impact of light on vision and health, and proposing artificial lighting solutions to support vision and protect the eyes.

According to the research team's report, the mission has made many new contributions, particularly in developing a system capable of surveying the effects of lighting under controlled light spectrum, illuminance, spatial distribution, and field of view conditions for clinical research.

The results help clarify the differences between the effects of natural and artificial light, providing data to guide applications in schools, offices, and high-intensity lighting environments.

The study also offers evidence-based solutions for vision-supporting lighting that can be applied in eye care and community lighting design.

In terms of socio -economic effectiveness, the project contributes to reducing the risk of visual impairment due to inappropriate lighting, serving as a basis for improving school lighting standards and community eye care. The research and technology transfer results help upgrade smart lighting systems, increase work efficiency, and reduce visual fatigue, thereby improving labor and learning productivity.

The project also supports interdisciplinary human resource training in the fields of ophthalmology and biomedical physics, creating a foundation for further research on light-vision interaction applied in diagnosis and visual aids. These results contribute to affirming domestic research capabilities in modern lighting equipment and solutions, while opening up broad applications in medicine, education , and the lighting industry.
