Reply to comment by Chris-1235 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

We can argue the philosophy of when something becomes perceived or just received by neurons but that's a different conversation. The title posed no comprehension issues for me because the only alternative meaning was illogical (because no one has an invisible face).

Just because the alternative meaning is illogical in your mind doesn’t mean the description is accurate. Accuracy is important, why wouldn’t you want to be as precise as possible? Especially when discussing scientific topics.

To me “invisible to the eye” means that the absence of sensory perception happens in the end organ of vision, not the areas of the brain that control consciousness. In reality, the information is visible to the eye. It’s an inaccurate title.

Actually it does. Logic or being logical isn't subjective. We know for a fact that people do not have invisible faces.

Invisible to the eye means the quality of being invisible is determined by the eye rather than it being a physical quality of the object the phrase is referencing.

The title is accurate enough to convey its meaning.

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.
