If the eyes were located toward the front of the head,the organism was probably an active swimmer.If the eyes were in the back of the head, the organism might have been an ocean bottom dweller. in most species,the eyes were located midway on the head-ideal for an organism that both crawled on the seafloor and swam in the water.

Natural Selection :D
the eyes are located in the center of its head so it is probebly adapted to walking on the sea floor as well as swimming

Yes, they have crystal eyes.

The head region of a trilobite is called the "cephalon." This part contains important features such as the eyes, mouth, and antennae, and is often characterized by a variety of shapes and ornamentation that can be used for species identification. The cephalon is distinct from the thorax, which consists of the segmented body, and the pygidium, which forms the tail end of the trilobite.
Trilobites with flat eyes lived above the surface of the ocean floor, those with stalks burrowed below it. Those with very large or no eyes may have lived in lightless depths; those with all-round vision may have been prey, while those with binocular vision may have been predators. Just like animals living today, really.
A phacops fossil is the preserved remains or trace of an extinct genus of trilobite, a group of marine arthropods that lived during the Paleozoic era. These fossils are typically found in ancient marine sediments and are characterized by their distinctive appearance, with segmented bodies, compound eyes, and a hard exoskeleton.
Being a trilobite would mean existing as a small, marine arthropod with a segmented body and a hard exoskeleton, thriving in the oceans of the Paleozoic era. You would experience life as a bottom-dweller, scavenging for organic matter and small prey, while navigating the diverse and dynamic underwater environment. With compound eyes, you would have a wide field of vision, helping you evade predators and find food, making your existence both fascinating and perilous. Overall, life as a trilobite would involve a constant adaptation to changing sea conditions and ecosystems over millions of years.
The colossal squid (Mesonychoteuthis hamiltoni) has the largest eyes of any known animal, reaching up to 11 inches (28 cm) in diameter. Their eyes are believed to be the largest among all invertebrates.
What does a yellow line in the eyes indicate.
