The incidence of cataract is expected to increase, primarily due to an aging population. However, human-induced environmental changes may also contribute. In this narrative review, we explore the connection between climate change, the depletion of the ozone layer, and modifiable risk factors for cataract development such as UV light exposure and pollution-related factors. Finally, we discuss preventative measures at both the individual and the societal level, including strategies to improve cataract care and reduce the carbon footprint of cataract surgery.
