Disorders involving cones can lead to various visual impairments. One common condition is color blindness, which occurs when one or more types of cones are absent or dysfunctional. Another condition is macular degeneration, which affects the central retina, including the cone-rich fovea, leading to loss of central vision. Understanding the histological structure and function of cones is crucial for diagnosing and developing treatments for these and other vision disorders.
