Lens physiology is the study of the structure and function of the lens of the eye. The lens is a transparent, flexible structure located behind the iris that helps to focus light onto the retina. Researchers in this field investigate how the lens develops, how it changes with age, and how it functions in different visual tasks such as accommodation (changing focus between near and far objects) and depth perception. They also study conditions that affect the lens, such as cataracts and presbyopia, and develop new treatments and interventions to maintain or improve lens function. Overall, lens physiology research aims to improve understanding of the visual system and contribute to the development of better interventions for vision-related conditions.
