What is the average lifespan of a cone cell?

The average lifespan of a cone cell in the human retina is estimated to be around 10 to 20 years. However, this can vary based on factors such as overall health, environmental conditions, and exposure to light. Cone cells, which are responsible for color vision and visual acuity, are continuously renewed and replaced throughout an individual's life. Thus, while some cells may last for years, the population of cone cells is maintained through ongoing cellular turnover.
