The development progress of low-melting optical glass used in precision molding by major material manufacturers in recent ten years is analyzed. The datas of major manufacturers in variety, refractive index and technical parameters are compared. The current situation of low-melting optical glass and the competitiveness of various manufacturers is analyzed and summarized. Suggestions on the follow-up research and development direction of low-melting optical glass are put forward.

The spectrophotometer as the basic optical instrument and the CIE Lab color space are used to establish a quantitative measurement method for glass color and color difference, which converts the color difference perceived by the human eye into specific values in proportion, and quantifies the color and color difference of glass.

Specially designed frame glasses play an important role in myopia intervention process, and the lens design mechanism has been constantly updated to improve the control effect of myopia. This paper mainly reviews the exploration and clinical application of frame glasses designed by high aspheric microlens in the prevention and control of myopia, aiming to provide reference for optometry practitioners.

At present, the myopia situation of juvenile and children in China is getting worse and worse, and the main battlefield of myopia prevention and control has quietly entered the family. Family education plays an irreplaceable role in preventing myopia. Using the network questionnaire survey method, the questionnaire was used to collect the eye use of children and juveniles in the family and the education level of parents on myopia prevention and control of their children. We find that family awareness of myopia prevention and control education is gradually being developed, and some families have some problems, such as insufficient professional ability, busy work, no time to manage their children, and contempt for children's eye education. The family education of myopia prevention and control should be paid more attention in our country, and the educational methods of family myopia prevention and control should be innovated and improved.

Regarding the shortcomings of the traditional teaching method of higher vocational education based on the logic of subject knowledge, taking the core curriculum of the higher vocational optometry major as an example, the research and application of curriculum system development and ADDIE learning context design based on the real work process logic to cultivat high-quality skilled talents are discussed.

China is a country with a large population of short-sight, and the huge demand has led to the rapid development of Chinese glasses industry. With the development of science and technology, the internet and a series of new media have made the idea of information management, digitalization and intelligentization come into people's life and have a great influence. Information management as the necessary guarantee for a modern glasses enterprises which is to seek greater development, has been increasingly valued by the majority of glasses enterprises. Based on the current social development, how to improve the efficiency of the traditional optometry industry and the future development trend of the optometry industry are discussed.A large number of enterprise applications also proved who first adopted modern information management, who can have a stronger competitiveness, and in the fierce market competition to stand out.

According to the "Double-high Level Plan", Tianjin Vocational Instinct took the lead in offering majors in optometry, optometric equipment application technology, and spectacles design among colleges and universities in the country.It opened the first domestic lens production technology major and the major of visual training and rehabilitation, forming a majors group with the major of optometry as the core major, and 5 majors are closely connected to the whole field of optometry. As the only majors group in the field of optometry selected into the "Double-high Level Plan", the construction mechanism and path, the formed model and standard of the optometry professional group of Tianjin Vocational University are of great significance to the guidance of similar higher vocational colleges. This paper analyzes the talent training mode, high-quality resource construction, teaching method reform, teaching team construction, training base construction, technical skills platform, social service. A summary of the construction modes, mechanisms and paths of professional groups in nine aspects, including international exchanges and cooperation and sustainable development of professional groups, provides a reference for the construction of similar professional groups in other colleges and universities.

The characteristic of vocational education is to cultivate high-quality technical and skilled talents, and the construction of training center is particularly important. Enterprises need specialized talents who can take up their positions urgently after graduation. How the school can let students experience the workplace environment as soon as possible, get familiar with the job, and simulate real production is the direction for higher vocational colleges. In order to simulate real production in real enterprise scene, the School of Optometry of Tianjin Vocational Institute has built five productive training centers integrating industry and education relying on the construction of "double highs" and cooperating with a number of leading enterprises in the industry. The school provides professionals for enterprises, and enterprises support the construction of the school for mutual benefit and common development. Through the improvement of software and hardware environment and the expansion of application functions, the training center has a more realistic professional environment, which is beneficial to the integration of teaching and work and shorten the period for students to adapt to employment. This model of training center built by industry and education integration has greatly improved the quality of talent training and social service ability.
