One-side optical horizontal deviation is one of most important parameters to evaluate the quality of assembled spectacle products. This article introduces a novel measuring method of laser line positioning, which can measure the one-side optical central horizontal distance and deviation quickly and accurately. Its measurement uncertainty is calculated. Meanwhile it is compared with other related methods for analysis, laser line positioning is an effective way to evaluate the quality of assembled spectacle products for its simplification in equipment used, convenience in operation and accuracy in measurement.

Spectacles are widely used in our daily life, however excessive nickel has adverse effect on people’s health. Therefore, domestic and foreign standards for nickel release control and detection have been promulgated. In this paper, the national standard GB/T 38009-2019, the international standard ISO/TS 24348-2014 and EN 16128:2015 were compared in terms of detection principles, detection methods and technical requirements. The purpose is to make relevant enterprises and testing institutions better understand the standards.

Sunglasses have become the daily standard accessories of many consumers. In combination with relevant national, industrial and group, standards, we comprehensively and systematically studied the technical requirements of sunglasses from the three dimensions of optical performance, durability and harmful substances, and extracted seven key indicators and corresponding required detection methods, including lens vetex power, prismatic power, transmittance, transmittance of ultraviolet spectral band, impact resistance, corrosion resistance to high temperature and nickel release. It is expected to serve as the basis for formulating product quality standards and evaluating product quality.

In emergency rescue, AR glasses can help rescuers get a faster and more accurate picture of the accident scene so that they can carry out rescue better. This paper analyses the role of AR glasses in emergency rescue, including its application scenarios, effects, problems and challenges faced, and discusses the development direction of AR technology in emergency rescue. With the continuous advancement of technology, AR glasses are expected to become an important tool for emergency rescue, helping rescuers to better respond to various emergencies.

125 college students were randomly selected to investigate the eye health status, the habit of using eyes, and understand their attitudes and behaviors towards eye protection. The results show that the myopia rate of college students is high, and the average score of attention to eye health is 7.35. The correction method is not good, and the recognition of eye health is one-sided, the use of eyes is not good, the continuous use of eyes is long, the academic pressure is high, the use time of electronic productsis is long, and the use of eyes is incorrect. College students should strengthen the general knowledge of eye health, develop correct eye habits, and learn to correct eye care knowledge, so as to improve the level of eye health cognition and improve the eye health status.
