Which is more sensitive: eye or fingertips?

P.S. touching or feeling

Define "sensitive" in a way that will make the comparison meaningful.

Fingertips are much more sensitive to touch.

If you softly touch the eye with some probe (which should obviously not be sharp and clean) you can hardly feel it whereas even the lightest touch of the fingertips is clearly noticeable.

Fingers are more sensitive to mechanical touch.
Eyes are more sensitive to the touch of photons.

Evidence for fingers being more sensitive because a larger part of the brain affects them,
"one can see that the hands have a disproportionately large representation compare to the eyes with respect to sensation"

But this doesn't take into account that visual perception, which is defined as one of the "senses", is actually processed in a different neural locale than the fingers. Similar to how smell has the olfactory bulb specialized for scents.

I conclude that fingers are more sensitive with regard to this post, but its arguable that eyes have more sensory "feeling", since the eye is sensitive to touch on the cornea AND sensitive to light on the retina. It's all relative.

I would say that both the eye and fingertips are equally sensitive in their own ways. The eye is able to detect light, colors, and shapes, while the fingertips are able to feel textures, temperatures, and pressure. Each of these senses is important for our daily lives and serves its own unique purpose. It is difficult to determine which is more sensitive as it ultimately depends on the context and what is being perceived. For example, the eye may be more sensitive when it comes to detecting small details in a visual scene, while the fingertips may be more sensitive when it comes to feeling the texture of a surface. Both senses work together to provide us with a complete understanding of our surroundings.
