The term "ojo" is the Spanish word for "eye." It refers to the organ that allows vision in humans and many animals. The eye is a complex structure that includes parts such as the cornea, lens, and retina, which work together to process light and create images. In various cultures, the eye is often associated with perception and awareness. For example, the evil eye is a superstition in many societies, believed to cause harm through a malicious glare. Additionally, the phrase "ojo" can be used in idiomatic expressions, such as "ojo con eso," meaning "be careful with that."
