Rods is a term that can refer to several different concepts, often depending on the context. In the realm of physics and optics, rods are a type of photoreceptor cell found in the retina of the eye. These cells are responsible for vision in low-light conditions and are highly sensitive to light. Unlike cones, which are responsible for color vision and detail in bright light, rods provide black-and-white vision and are crucial for peripheral vision and night vision.

In engineering and manufacturing, a rod is a long, slender, solid piece of material, typically metal or plastic. Rods are used in a vast array of applications, from structural components in machinery and buildings to fasteners and decorative elements. They can be manufactured in various shapes, including round, square, or hexagonal, and come in a wide range of materials, each with specific properties like strength, flexibility, and resistance to corrosion.

The term "rods" can also appear in colloquial or slang usage, which can vary significantly by region and culture. For example, in certain automotive subcultures, "rods" might refer to hot rods, which are custom-built or modified vintage cars. The specific meaning of "rods" is therefore best determined by the surrounding information or the specific field of discussion.
