Man is created in the image of God who sees all things He is creating. His vision is universal, infinite and eternal. The human ability to "see" which is at once a physical-spiritual activity is a participation in the vision of God.
The human eye is a marvel of design instantly focusing and adjusting light levels of the image reflected by light from the outer world. The mind's eye is an intelligent interpretation of reality which differentiates between colors, shapes and distances thus achieving a unified field of view.
Despite its ability, the eyes are limited to the visible spectrum of light. A bee, for example, has eyes shifted toward the ultraviolet which means that red is black but the bee can see to navigate by the sun on a cloudy day because clouds cannot block ultraviolet radiation. This means the God has optimized the bee's vision for its purpose in life.
Beyond the visible entities that the eye can see, there is an infinitesimal world of cells, molecules and atoms which the human eye cannot see. Take the tiny flower alisum. It has to be magnified 20,000 times in order for our eyes to see single grains of pollen within it. So, our eyes without the aid of an electron microscope can see pollen but not its single grains which are far too small to be seen by the human eye.
Our eyes cannot see details in movements that are too fast or too slow. The propeller of an airplane is seen as a rotating blur and the blossoming of a rose can only be seen in stages unless we employ time lapse photography.
Since our eyes can only see light sources and creatures by reflected light, the speed of light itself (186,000 mps) places limitations on the reality we see. Any creature we see is always in the past tense but this does not make any difference for creatures close to us. We see them as they "actually" are at that moment. When we look at the night sky instead, we see the past. The Crab Nebula, for example, is 6,500 light years away, so the way it looks to astronomers today is what it looked like 6,500 years ago. So what we see is not the present reality.
The universe is real but the way we perceive it is a projection of what takes place between the observer and the phenomena. So called "solid matter" is mostly empty space made up of atoms, or bundles of vibratory energy. The solidity we experience is mostly the property of fingers which touch and eyes which see only the visible spectrum reflected. (Robert w. Godwin, One Cosmos Under God, Paragon House, St. Paul, Minnesota, 2004, p. 42) When we move beyond material entities, our eyes cannot see them at all no matter what instruments we use.
