Can Eye Color Actually Change?
Can a person's eye color evolve over time? While it's widely accepted that eye color can shift as we get older, is it truly feasible for someone who starts out with dark eyes, such as black or brown, to have them transition to blue later in life? This question sparks intrigue among many, especially since there's a considerable community that holds this belief. So, what does scientific evidence say about the possibility of such changes in eye color?

Eye color can indeed change over time, but significant shifts from dark colors like brown or black to lighter colors such as blue are generally not possible. Here’s a breakdown of how eye color can change and what factors are involved:
Main Points
- Eye color can change due to various factors but typically does not shift dramatically from dark to light.
- Common reasons for gradual changes include aging, health conditions, and environmental factors.
Explanation
-
Genetics and Eye Color: Eye color is primarily determined by genetics and the amount of melanin in the iris. The more melanin present, the darker the eye color. Brown and black eyes result from higher melanin levels, while blue or green eyes are from lower levels.
-
Natural Changes Over Time:
- Children and Aging: Many babies are born with blue eyes that may change as they grow, usually settling into their permanent color by the age of 3. As people age, their eyes may become lighter or develop a yellowish tint due to changes in the lens or the aging process.
- Health Conditions: Certain health issues, such as cataracts or Wilson's disease, may alter eye color. These changes can be due to structural changes in the eye rather than a genuine shift in pigment.
-
Environmental Factors: Exposure to sunlight can sometimes influence eye color by enhancing pigmentation. However, this typically does not result in a major color change from dark to light.
Next Steps
- Observe for Changes: If you notice gradual changes in your eye color (e.g., slight lightening), consider tracking them over time.
- Consult a Health Professional: If you experience sudden changes in eye color, such as rapid lightening or discoloration, it may be prudent to seek medical advice to rule out underlying health concerns.
- Eye Protection: Protect your eyes from excessive UV exposure by wearing sunglasses to maintain overall eye health.
Understanding the reasons behind eye color changes can help alleviate concerns, but significant shifts from dark to blue are not supported by scientific evidence. If you have more questions about eye health or related topics, feel free to ask!

Blood in Urine: Seeking Guidance
A 20-year-old female weighing 140 pounds has not been taking any medications or supplements, and has no prior or current medical conditions. Her menstrual cycle last occurred two weeks ago. While at work, she observed blood in her urine, which appeared light red but darker than pink. Accompanying this symptom, she has experienced some abdominal discomfort. Notably, there was no evidence of blood on her underwear, only when she urinated. Additionally, she felt a moment of lightheadedness upon noticing the blood, which has since subsided; she attributes this feeling to her anxiety about the potential seriousness of the situation. Given these symptoms, what could be the likely cause? She is uncertain whether to visit the emergency room or to wait until urgent care is available tomorrow for a consultation. As she recently relocated and does not have a primary care physician yet, her anxiety is heightened.
Exploring Endolymphatic Hydrops: Could This Be My Condition?
34 years old / Female Current weight: 165 lbs Navigating the challenges of motherhood In early December 2025, I caught a cold. By mid-December, my right ear felt blocked, but I attributed it to the cold virus. As New Year approached, I experienced another cold, which coincided with an onset of ringing in my ears. Disturbingly, sounds started to seem altered from the affected ear, accompanied by a persistent fullness in that area. Additionally, I noticed twitching of my eye and swelling in the salivary gland on the same side. My primary care physician prescribed a decongestant and Flonase; however, because I am currently breastfeeding, I hesitated to take the medications as directed. On January 27, I was evaluated by an ear, nose, and throat specialist, who requested a hearing assessment the following day. The results indicated that I had sensorineural hearing loss affecting my low-frequency hearing range (250 Hz to 500 Hz). The doctor prescribed a steroid with the hope of addressing the issue promptly. Now on day 10 of steroid treatment, I have experienced significant relief. Remarkably, I've noticed a substantial amount of thick, putty-like mucus clearing from my nasal passages. The pressure in my ear has subsided, and sounds are returning to normal, though I still perceive a slight ringing — possibly just a touch of hearing loss remains. What concerns me is whether ongoing sinus congestion could be the root of these symptoms or if I might genuinely be dealing with endolymphatic hydrops. Notably, I have not experienced any episodes of dizziness. In the evenings, I tend to feel considerable pressure building on the right side of my head, almost as if my sinuses are becoming blocked once more. I would greatly appreciate any insights or advice on this matter, as I find myself in a state of uncertainty regarding my condition.
Gene Testing Outcomes Suggest Elevated Risk for MPN
A 27-year-old male of Irish heritage recently conducted a commercial gene analysis, and here are the findings: - **Rs12340895 (C;G)** Result Interpretation: "Doubles the likelihood of developing V617F-positive MPN." - **Rs3780374 (A;G)** Result Interpretation: "Significantly raises the probability of V617F-positive MPN manifestation." Based on my research, it appears that having these two genetic markers indicates a strong predisposition to this particular form of cancer. What steps should I consider taking to either prepare for or potentially postpone the onset of this condition? Should I discuss these findings with my healthcare provider? My studies suggest there isn’t a definitive cure for this condition.
Understanding Preseptal Cellulitis in Children
Hello everyone. I'm reaching out for assistance. My 6-year-old son recently experienced a concerning issue. He woke up on Friday with significant swelling around his eye, nearly closing it entirely. We quickly took him to the emergency room, where doctors diagnosed him with preseptal cellulitis. They prescribed antibiotics, specifically cephalosporin, as part of his treatment. However, after approximately 30 hours on the medication, I’ve noticed that his condition seems to have deteriorated. We’ve been applying warm compresses, which help reduce some swelling temporarily, but he now has a noticeable bump right in the center of the affected area. This morning, he woke up again with his eye completely shut. I’m uncertain whether I should return to the ER for further evaluation. I appreciate any advice or insights you can provide. Thank you!
14-Year-Old Male with Cough and Rash Symptoms
My 14-year-old son, who stands at 5 feet 3 inches tall and weighs 149 pounds, has been experiencing persistent cough and cold-like symptoms for slightly over a week. He stayed home from school on January 30 and February 3 as he was feeling unwell, but aside from that, he has managed to attend school. The predominant issue has been his cough. Initially, he had a runny nose for a couple of days, but that symptom has since resolved. He has not complained about a sore throat or experienced any fever. This afternoon, he reported developing a rash with red spots. He mentioned that it itches a little, but it's not uncomfortable, and he does not feel any pain. The rash is primarily located on his abdomen and chest, with some patches on his legs and a little on his arms, but there are no spots on his back. I checked his temperature, which was recorded at 99.4°F. He is fully vaccinated according to the standard vaccination schedule recommended by pediatricians in the United States. Our residence is near Vancouver, WA, in case that information is pertinent. Additionally, we have not changed any laundry or personal care products recently. What could this condition possibly indicate?
