As one of the hard tissues of fish, eye lens has the characteristics of stable structure, resistance to erosion, and easily accessible. It contains a large amount of protein, which records much chemical information, and has been applied to a certain extent in the age determination of fish. In recent years, with the continuous innovation and progress of geobiochemical technology, the trace element and stable isotope information of fish eye lens has been paid more and more attention to by scholars at home and abroad. Here, the application of determined age, habitat reconstruction and feeding ecological tracking were reviewed in terms of the diameter and weight, microstructure, trace elements and stable isotope of the eye lens, after analyzing the composition and growth pattern of fish eye lens and comparing the advantages of eye lens and other tissues for stable isotope analysis, the research methods, application status and development prospects for stable isotope of eye lens in fish life history information, especially in feeding ecological tracking and habitat reconstruction were summarizied to provide reference for future research.
