Down at those depths, there is very little light.
Large eyes are able to channel and focus what little light there might be.
Evolution have granted those deep sea living creatures with larger eyes over the time.
At very deep depths, there is no sunlight at all. It is all filtered away by the water/ocean above. Still some organisms and even fish are able to make light. They often do this to attract prey, but can them selves become prey to those able to see.

How do fish survive in the ocean?
Fish survive in the ocean by their gills. Fish need oxygen too, just like many other living things. They do not breath the water. Their gills receive oxygen and they breath that way. that's why fish CAN live under water. Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fish include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, and viperfish.Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor.Deep-sea organisms generally inhabit bathypelagic (1000m-4000m deep) and abyssopelagic (4000m-6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200m-1000m deep) zone as well.

Bathyal zone animals?
The bathyal zone is a marine ecologic realm that is deep below sea level and is in permanent darkness. The animals that live there are carnivorous because there is no primary production of plants. Eels, squid, crustaceans, some fish, large whales, sponges, octopuses, and sea stars live in this deep sea area.
Are blobfish fish?

Why are the fish eyes so large and placed far apart?
In the very low depths, there is very little light. Large eyes enable the fish toy channel and focus what little light there might be. Evolution has bestowed deep sea living creatures with larger eyes over time. Eyes on the sides of their heads allow the fish to have a large spectrum of sight. As a result, a fish can more easily spot and avert predators.
Explain why most deep sea fish have small eyes or none at all where mid fish such as the lantern fish have very big fish?
as there is no light in deep waters,deep sea fishes get their eyes reduced during evolution.due to the availability of some light at middle of sea fishes living there have bigger eyes for clear vision.
