Eyes that glow in the pitch-black night make for many a scary tale. But why do wolves' eyes glow in the dark? Wolves have a special light-reflecting surface right behind their retinas called the tapetum lucidum that helps animals see better in the dark.
WOLVES: Wolves have distinctly almond-shaped eyes that tend to be more closely set on the face and are slanted, with the corners of the eyes lining up with the outer base of the ears. This forms a 45-degree angle on the face from the eyes to the ears. Wolves' eye colors range from amber to pale yellow and even green.
Coyotes, wolves and dog's eyes usually have a fiery white glow. A bobcat's eyeshine is yellowish white. A bear's eyes will glow fiery orange.
Wolves have a special layer of reflective cells behind their retinas called the tapetum lucidum. The retroreflective nature of the tapetum lucidum causes it to reflect light back along the same path it arrived, which means that light passing through the retina is reflected back into the eye.
Answer and Explanation: Wolves can appear to have red eyes when the light is just right, but they do not appear red permanently. Wolf eyes have the tapetum lucidum that acts like a mirror behind the retina. This light-reflecting surface helps the wolf see better in the dark by making light bounce back to the retina.

Wolves also have keen vision, and can see in the dark better than we can, although they can't distinguish colors as well as we can. (In particular, like dogs they can't distinguish shades of red from shades of yellow and green.)
Wolves can only have appearing blue eyes when they have a genetic defect (such as cataracts, which is really rare). In a natural way, wolf eyes never come in blue. The Iberian wolf you mentioned most likely had two different coloured eyes due to genetic defects.
Eye Color. An Alpha's eyes glow red. Yellow is the most common eye color among Betas and Omegas. Some Betas and Omegas have blue eyes.
In the films, Lycans' eyes are shown to change into a cloudy deep blue when they are partially transformed. In the novelizations, their eyes are described as changing into a solid cobalt blue, the same as the original Werewolves.
Amber-coloured eyes are most often seen in Asian and South American areas of the world. A pure amber colour is more solid and uniform (hazel eyes, which amber colour can be confused with, are not), and appears to glow. The colour (nicknamed 'wolf-eyes') is more common in animal species than it is humans.
But why do wolves' eyes glow in the dark? Wolves have a special light-reflecting surface right behind their retinas called the tapetum lucidum that helps animals see better in the dark. When light enters the eye, it's supposed to hit a photoreceptor that transmits the information to the brain.

So why does it occur? The iris of the eye is colored by melanin (the same stuff that gives pigmentation to our skin). Heterochromia occurs as a result of excess or lack of melanin in one eye. It may be congenital, or develop over time.
Wolves generally avoid human interactions, unless they have become habituated to people. Please do your part to keep wolves the way they belong—wild. Keep your distance from wolves. Remain at least 100 yards away when watching or photographing them.
Unbelievable as it may seem, the answer is yes—natural purple eyes do exist. Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade. For most people, this striking eye color can only be achieved with the help of colored contacts.
“In most parts of the world black wolves are absent or very rare, yet in North America they are common in some areas and absent in others”, said the study's senior author, Tim Coulson, a Professor of Biology at the University of Oxford.
To start with, the most common eye color in wolves is gold. This is a characteristic that wolves are often revered for, as it is very striking and beautiful. This is the color that is by far the most common with a variety of shades, some appear more yellow and others more brown.
Amber eyes are extremely rare. Most sources say that only about 5% of people have true amber eyes. Coming up with a hard and fast number or percentage, though, is not as easy as you might think—there simply haven't been enough large-scale studies done to quantify eye color prevalence with certainty.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Highly social animals like dogs (and wolves) respond to this depending on the situation. Direct eye contact in these canids is often a behavior in establishing or challenging dominance, so staring at a dog or wolf makes them uncomfortable, if not irritated.
During a close encounter with a wolf, people should do the following: Stand tall and make themselves look larger. Calmly but slowly back away and maintain eye contact. If the wolf does not run away immediately, continue making yourself large, keeping eye contact, and backing away.
They can hear sounds up to a frequency of 25khz, with a maximum of up to 80 khz according to some researchers—much greater than a human's upper limit of 20 khz and possibly even a dog's at 47 to 65 khz.
