Reply to comment by Feudamonia in The brain can rapidly detect and process fearful faces that are otherwise invisible to the eye. There appears to be a neural pathway for detection of fear, which operates automatically, outside of conscious awareness. by Wagamaga

It is not accurate enough to convey its meaning because its meaning is that the eye did not perceive the stimulus when in reality the eye did perceive the stimulus and the cerebral cortex did not perceive the stimulus. Those are two separate parts of anatomy and in a scientific discussion that distinction matters a great deal.

You're getting confused between sensation and perception. Sensation occurs when sensory receptors detect sensory stimuli. Perception involves the organization, interpretation, and conscious experience of those sensations.
