Brian was surprised to find that the originally silver-gray night had, in his eyes, turned into a slightly dimmer but vibrant, morning-like world!
He could see in the dark now.
Beyond that,
a faint red light enveloped his entire field of vision.
Was this ultraviolet light?
With curiosity, Brian left the area to find a high vantage point where he began to study his eyes.
An eagle's vision is actually not much different from that of humans, but it has about eight times the range and excels at capturing moving objects, although its night vision is weaker.
He wondered what species this was, as its night vision was so strong!
Brian was astonished to find that he could not only see in the dark and perceive ultraviolet light, but he could also freely adjust the focus of his vision, clearly seeing tiny details at least three to four miles away. He could integrate the human perspective into this sensory experience, making things in his view more vivid and clear.
