Med."],"abstract":"<jats:p>Infrared (IR) light provides non-invasive, depth-resolved imaging and diagnostic capabilities, allowing for precise tissue analysis and real-time monitoring across various applications. In recent years, IR light-based technologies\u2014encompassing IR spectroscopy, IR imaging, IR thermography, IR eye tracking, and IR therapy\u2014emerged as a powerful tool in ophthalmology, offering valuable insights into multiple aspects of eye health. Its ability to detect subtle changes in ocular tissues and deliver real-time data holds significant potential to enhance both diagnostic accuracy and treatment efficacy in eye care. This review highlights recent advances in the application of IR light-based technology in ophthalmology, focusing on applications such as quantitative ocular surface thermography, depth-resolved structural imaging, functional monitoring, and IR based therapeutic applications in ophthalmology. IR light\u2019s ability to penetrate ocular tissues non-invasively allows for detailed assessments of eye physiology, facilitating early disease detection and supporting personalized treatment strategies. While IR technology exhibits great potential, key challenges remain in its optimization\u2014notably improving spectral resolution, depth penetration, and device miniaturization for expanded clinical integration. Finally, the current challenges and future prospects of IR light based-technology in ophthalmology are discussed, contributing to early diagnosis, monitoring disease progression, and evaluating treatment outcomes.<\/jats:p>","DOI":"10.3389\/fmed.2026.1888199","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T05:39:07Z","timestamp":1783661947000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Recent
