Question:
What thikness can the human eye see light through?
i want to know the thickness eyes can see light through and i want references.
Answers:
The human eye can detect a light source down to 3 candlepower, which is barely a dim blur. But your question implies that the eye can see through intervening thicknesses of objects. The thickness of the object determines how much light may pass through it, not that the eye can see the light beyond it.
