Yes, an iris (the colored part of the eye) can change color, but it's usually due to injury, disease, medication, or inflammation, not a normal process, while garden irises often seem to change due to cross-pollination or new seedlings taking over, not the original plant changing hue. In humans, true iris color change is rare and warrants a doctor visit, but can happen with pigment dispersion syndrome, Fuch's heterochromic iridocyclitis, or certain glaucoma drugs, while garden irises might appear different due to bee-pollinated seeds growing nearby or stronger varieties outcompeting weaker ones over time.
Iris cannot change color. Usually, when a customer notices this unusual occurrence, what has happened is that the purple (or red, or pink, or blue, or yellow, or black, or whatever color) Iris has grown into another nearby patch and the one color has dominated (or crowded out) the other.
The answer is yes and no. Healthy adult irises almost never truly change hue; most “changes” are lighting or pupil-size illusions. A sudden, lasting shift can be a sign of injury, disease, or a side effect of certain medications. If these changes occur, it's essential to schedule an appointment with your eye doctor.
Temperature changes, chemical drift, transplant issues, or even random rhizomes dug up by a dog can cause a stand of iris to change color. Irises do not always bloom every year and an older variety may be asserting itself in your cultivar's fallow period too.

And, the multitude of color choices--from blue, purple, red, yellow, pink, white and all the shades in between--make it easy to fit them into sunny, perennial flower beds. Their elegant, fan-shaped flowers have three drooping petals called falls and three upright petals called standards.
There are two different kinds of melanin in the iris. Eumelanin produces a deep, chocolate brown color, while pheomelanin produces more of the amber, green, and hazel colors.
Established bearded and beardless irises are usually drought tolerant after they mature. Often supplemental watering is only needed during prolonged periods of hot, dry weather. If you garden in a climate that has humid and wet summers, watering may not even be needed for weeks at a time.
You CANNOT change the color of an iris by making the soil less acid or less alkaline (this works with hydrangeas, but not with most plants). The color of the iris is pretty much “locked in” to its genetics.
The two rarest eye colors are generally considered violet/red (due to albinism) and heterochromia (different colored eyes), both appearing in less than 1% of people, with green and gray eyes also being exceptionally uncommon, usually around 2-3% of the population. Red/violet eyes result from a severe lack of melanin (pigment) where blood vessels show through, while heterochromia involves two different iris colors or patterns, often benign but sometimes linked to conditions.
Frequently Asked Questions About Eye Color Changes
Being stressed or feeling strong emotions won't change the pigment itself, but because adrenaline widens the pupil, the iris may look temporarily darker or brighter until the pupil shrinks again. No lasting color shift occurs when you are stressed.
Uveitis: Inflammation of the uvea, which includes the iris, ciliary body, and choroid. The cause is most often not known. It may be related to an autoimmune disorder, infection, or exposure to toxins. The type of uveitis that causes the worst red eye is called iritis, in which only the iris is inflamed.
"The factors that can cause eyes to change colors—or appear to have different colors—include genes, diseases, medications and trauma," said Omar Chaudhary, MD, an ophthalmologist in Potomac, Md.
Many iris flower more than once a year. In addition to blooming in the Spring, the reblooming iris varieties bloom again in the Summer and Autumn. Remontant iris, commonly called re-bloomers, or re-blooming iris include several types within one category.
If you find that your dark brown eyes are getting lighter, there could be several explanations. Aging is a natural cause, as melanin levels in the iris can decrease over time. Additionally, prolonged exposure to sunlight can sometimes lighten eye color.
Lucifer's eye color varies by interpretation, often depicted as golden or blue in his angelic form and shifting to fiery red, black, or other intense colors in his demonic states, reflecting his fallen nature, with different fandoms and shows giving unique variations like carmine red or rose gold.

Sleep deprivation does not directly cause yellow eyes, but it can contribute to liver stress and worsen existing conditions.
Late July through mid August is the best time to plant, move or divide iris. Iris is one of the most popular perennials in the garden and easy to grow. Although they provide pleasure for many years with little care, periodic dividing is an important cultural practice for maintaining plant health.
Irises require at least a half-day (6-8 hours) of direct sunlight. Some afternoon shade is beneficial in extremely hot climates, but in general irises do best in full sun.
Pruning or trimming the foliage protects the plant from fungal and bacterial diseases caused by too much moisture on the leaves. Irises are vulnerable to blight, leaf spot, and soft rot. Left to overwinter, they are also vulnerable to a major iris pest, called the iris borer.
Ensure these plants receive a minimum of 6 hours of sunlight daily; check annually for any changes in their sun exposure. Irises need at least 6 hours of sun per day if they are to flower to their fullest potential, and you should evaluate their location every year to ensure this demand is met.
Healthy green leaves should be left undisturbed all summer, but diseased or brown leaves should be removed. In the fall, trim the leaves to a height of approximately six inches. Remove weeds, leaf debris, grass roots from Iris beds. In regions with especially cold winters, lay winter protection over the rhizomes.
