People's eyes can appear to glow or reflect light due to camera flashes (red-eye), natural light reflection off the retina, or certain medical conditions like cataracts or retinoblastoma (leukocoria), with animal eyes often having a special reflective layer (tapetum lucidum) for night vision that humans lack, making their "glow" more pronounced. In photos, the red glow comes from blood vessels behind the retina, while in animals, it's from the tapetum, acting like a mirror. A white or yellow glow in a child's eye (leukocoria) can be a serious sign of cancer or other diseases, requiring immediate medical attention.
The light that misses those photoreceptors hits the tapetum lucidum, reflecting that extra light, giving it another chance to hit those receptors and lighten the landscape for its owner to see. When some of that light is reflected, this is when you get that “glowing” eye appearance.
When "Glowing Eyes" Indicates Pathology. While eyeshine itself is benign, abnormal appearances warrant evaluation: White reflex (leukocoria): A white rather than red glow may indicate serious pathology including retinoblastoma, cataracts, or retinal detachment—this requires urgent ophthalmology referral 2.
Two things could follow: Red-brown iron deposits (siderosis) or white chalky calcium (chalcosis) can tint the iris. The iris tissue thins, letting more light reflect from the pal posterior layer and making the eye look lighter.
The flash hits the back of your eye and reflects off the blood-rich choroid layer, creating that bright red glow in the photo! Older cameras made this super common because the flash was placed right next to the lens.
Allergies, dehydration, medications, and eye diseases are common causes of glassy eyes. Lubricating eye drops, allergy medications, and lifestyle changes can treat smooth, glossy, or watery eyes. Drink plenty of water, wear sunglasses, and practice good hygiene to prevent glassy eyes.

Although eyes with eyeshine are said to glow in the dark, they actually do not glow – they reflect available light. Light enters the eye, passes through the retina, and strikes a mirrorlike membrane called the tapetum. The tapetum reflects the light back through the eye to the light source.
The rarest eye colors are red and violet, typically seen in people with albinism due to a lack of melanin, followed by green eyes, which occur in only about 2% of the global population, making them the rarest common color, and grey eyes, often mistaken for blue but distinct, also very rare. Conditions like heterochromia (different colored eyes) are also exceptionally rare, while brown is the most common.

Eyeshine is a visible effect of the tapetum lucidum. When light shines into the eye of an animal having a tapetum lucidum, the pupil appears to glow. Eyeshine can be seen in many animals, in nature, and in flash photographs.

The tapetum lucidum is an iridescent reflective substance that covers the back of the eyes of animals, which is why they have an eye shine. Since we lack the tapetum lucidum, we just have “red eye” instead because there's no reflective substance at the back of our eyes.
