In most people, the answer is no. Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age. What determines eye color is the pigment melanin.
Hazel eyes play a delicate game of limbo between brown and blue, having less pigment than brown and more than blue. Eye color can change through the years as amount of pigment in the eyes differs based on genetics.
As much as we'd like to believe that hazel eyes can change color like a mood ring does, most of the time it's really just a trick of the light! What you're seeing is actually Rayleigh scattering — the same phenomenon that makes the sky appear blue.
Hazel eyes are sometimes mistaken for green or brown eyes. They are not as rare as green eyes, but are rarer than blue eyes. Only about 5 percent of the population worldwide has the hazel eye genetic mutation.
From 10 to 15 percent of the Caucasian population will see a change in their eye color as they age. In the case of you and your father, the eye color changed due either to a gradual decrease in the number of pigment granules in the iris or to a degradation of the granules.
The most likely explanation for a change in eye color is to change the amount of pigment producing proteins made. There are lots of cases where something in the environment changes the amount of protein that is made. The color of a person's clothing can “bring out” their eyes, making them appear a different color.
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.

What ethnicity has hazel eyes? Anyone can be born with hazel eyes, but it's most common in people of Brazilian, Middle Eastern, North African, or Spanish descent.
People who had deep brown eyes during their youth and adulthood may experience a lightening of their eye pigment as they enter middle age, giving them hazel eyes. Conversely, someone born with hazel eyes might see their irises get darker as they grow older.
Green is the rarest eye color of the more common colors. Outside of a few exceptions, nearly everyone has eyes that are brown, blue, green or somewhere in between. Other colors like gray or hazel are less common.
Hazel is the most attractive eye colour in females
Only green eyes seemed to suffer at all, with only 11% of matches reached. Blue and brown, the most popular for men, trended towards the bottom middle of the list, with brown eyes - the most common in the world - receiving only 13% of all matches.
Another possibility is that there may be modifier genes. These are genes that would affect how much melanin BEY2 or GEY make. For example, you could get a gene that has GEY make more melanin or BEY2 make less. The end result would be hazel eyes.
According to the World Atlas, only about 5% of the world's population has hazel eyes, making them extremely uncommon. Meanwhile, blue eyes account for about 8 to 10% of the world population whereas brown eyes dominate at a whopping 79%. However, this doesn't make hazel the rarest eye color.
If your eye color is Hazel, then your eye color personality reveals that you are imaginative, determined, adventurous, and open to trying new things. You have a thing for taking risks. You are filled with strong and active energy.

Why are my hazel eyes getting lighter? As you grow up, the melanin level increases around your pupil, making the eye darker. However, 10-15% of Caucasian eyes change to a lighter color as they age, as pigment in the iris changes or degrades.
Pupil size can be affected by your emotions, which is why some people may think their eyes change color when they are feeling angry, sad, etc. However, while your eye may look momentarily different, your actual eye color isn't changing.
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
Advantages of Hazel Eyes
The levels of melanin in hazel eyes may offer some benefits to the brain. People with hazel eyes appear to be less likely to have nerve damage from environmental noise than people with blue eyes. There are some beliefs that people with hazel eyes tend to have a more positive outlook on things.
Hazel eyes have also been voted as one of the most attractive eye colours and can, therefore, be argued to have the best of both worlds, health and beauty. Green eyes are incredibly rare, which may be the reason as to why some believe this to be the most attractive eye colour. Grey eyes are also a rare eye color.
Lighter-colored eyes have less pigment to protect against sun damage and UV radiation compared to darker-colored eyes. This means that people with green, hazel, or blue eyes are more sensitive to light and more susceptible to UV damage.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
