Hello, I'm an expert in entomology, which is the scientific study of insects. I'd be happy to help answer your question about the vision capabilities of a cockroach.

Roaches, like many insects, have a compound eye structure, which means their eyes are made up of many tiny lenses that work together to form an image. This type of eye allows them to see a wide field of view, but the image quality is not as sharp as that of human eyes.

Roaches are primarily nocturnal creatures, and their eyes are adapted to low-light conditions. They can detect movement quite well, which is a survival mechanism to help them avoid predators. However, their color vision is limited, and they primarily see in shades of gray.

So, to answer your question, can a roach see you? Yes, a roach can see you, especially if you are moving. However, they won't perceive you with the same level of detail and color that you would see yourself.

Actually, there's no such thing as CSDS because cockroaches see you long before you see them. ... Additionally, light-sensitive cells in cockroach eyes, called photoreceptors, allow the critter to see in near total darkness. Scientists have determined roach eyes can absorb one photon of light every 10 seconds.read more >>
