Scientific Explaination
It is only the flame wherefrom rays travel to the eye-lenses and not from intervening objects.
The rays fall on the eye from small or big objects making their image on retina accordingly.
It is an illusion. All observations are in succession in small intervals of time due to high velocity of light. The eye can see only those objects whose cover is transparent like glass. It can not see objects covered by opaque bodies.
There is a least distance for distinct vision for a normal eye. It can not see objects clearly or totally at a lesser distance than this. Applied collyrium comes below this limit. Similar explanation as in 7.
Agreeable
This is due to different characteristics and visual power of their eye lenses which work in darkness.
It is clear from above that it is not possible to see an object until light-rays of visible range through or across it fall on eye. Thus, despite non-moving nature of the eye, it comes in indirect contact with the object through the light. The word, 'non-contactile', therefore, need redefining as partially or
