I think the vast amount of seeing marine creatures is a massive counterexample. Evolutionary biologists think that the ability to detect any photons grants an advantage: in environments where there is light, eyes evolve, even when the light is dim. It's only in completely lightless environments that eyes no longer provide an advantage (i.e. abyssal plain or caves).

Agreed, the sea creatures have evolved to capture even more light. I'm only guessing, but I would think the pressure and temperature sensors on fish would be more important than sight?

You mean, sensors to detect at a distance? For temperature, most deep-sea creatures have large amounts of insulation to survive the cold & thus would be difficult to detect (especially since water is also an insulator). For pressure, those exist and are called tendrils/antennae.
