What Causes Hazel Eyes, and Why Do They Change Color?

Question

I recently noticed that my hazel eyes seem to change color depending on the lighting, and I wanted to understand more about what makes hazel eyes unique. From what I understand, hazel eyes are a mix of green, brown, and gold, but what exactly determines their shade and intensity?

I read that hazel eyes contain a mix of melanin and Rayleigh scattering, which causes them to shift colors based on lighting, surroundings, and even emotions. But does this mean that hazel eyes can permanently change over time, or is it just a temporary effect?

One thing that fascinates me is that hazel eyes are considered one of the rarest eye colors, found in only about 5-8% of the world's population. Is eye color purely genetic, or can factors like diet, sunlight exposure, or aging influence it?

Are there any natural ways to enhance the brightness or contrast of hazel eyes? I’ve read that certain foods, hydration, and even Ayurvedic remedies like Triphala eye wash can improve eye clarity and brightness—do these actually work?

If anyone has hazel eyes, do you notice your eye color shifting? Have you found any tricks to make them appear more vibrant?

Dr Sujal Patil · Accepted Answer

Thank you for sharing your concerns about your hazel eyes. It’s completely natural to notice changes in how they appear under different lighting or surroundings, and I understand how fascinating—and sometimes puzzling—that can feel.

Hazel eyes have a mix of pigments and reflect light differently based on lighting, clothing, or even emotional states. These temporary shifts are due to the scattering of light and melanin distribution in your iris, which is perfectly normal. Permanent color changes are rare but can happen with age or certain medical conditions, though those are uncommon.

If you’re looking to enhance brightness or contrast, staying hydrated, eating a diet rich in antioxidants (like berries and leafy greens), and protecting your eyes from UV light can help your eyes appear more vibrant. Some people find Ayurvedic approaches, like Triphala eye wash, soothing, but there’s limited scientific evidence for color enhancement.

If you notice any sudden or permanent color changes, or if your eyes feel irritated, I recommend seeing an eye specialist for a closer look. Otherwise, your eyes sound healthy, and small lifestyle changes can help maintain their vibrance.

Hazel eyes are unique due to their mix of green, brown, and gold, influenced by melanin levels and light scattering. Their color may appear to shift based on lighting, surroundings, and even emotions, but this is usually a temporary effect rather than a permanent change. Eye color is primarily genetic, though factors like aging, overall health, and exposure to sunlight can subtly influence brightness over time. Ayurveda emphasizes eye health through a balanced diet rich in leafy greens, carrots, and ghee, which nourish the eyes. Triphala eye wash and cooling herbs like rose water and fennel can enhance eye clarity and reduce strain, making the natural color appear more vibrant. Staying hydrated and reducing eye strain from screens also helps maintain a bright and healthy gaze.
