Why Do My Eyes Turn Yellow Upon Waking Up? - Ophthalmology

Experiencing yellowing of the sclera (the white part of the eye) upon waking can be concerning, but there are several potential explanations for this phenomenon. It's important to understand that the appearance of yellow in the eyes can be attributed to various factors, and in your case, it seems to be temporary, lasting only for a few minutes after waking up.

One common reason for temporary yellowing of the sclera is related to the accumulation of bilirubin, a yellow pigment that is produced during the breakdown of red blood cells. Normally, bilirubin is processed by the liver and excreted in bile. If there is a slight disruption in this process, such as dehydration or a mild liver function issue, it can lead to a temporary increase in bilirubin levels, causing the eyes to appear yellow. However, since you mentioned that this yellowing disappears within 5 to 10 minutes, it is less likely to be a serious liver issue.

Another possible explanation is related to sleep and the body's natural processes during the night. While you sleep, your body goes through various metabolic processes, and the eyes may experience changes in blood flow or fluid accumulation. When you wake up, the sclera may appear slightly yellow due to these changes, but as you move around and your body re-establishes normal circulation, the yellowing resolves.

Additionally, environmental factors such as allergens or irritants can contribute to eye discomfort and changes in appearance. If you are experiencing allergies or have been exposed to irritants, this could lead to temporary changes in the appearance of your eyes upon waking. Allergies can cause inflammation and redness, which might be perceived as yellowing, especially if there is accompanying irritation.

It's also worth considering that lifestyle factors, such as diet, hydration, and sleep quality, can impact the appearance of your eyes. Dehydration, for instance, can lead to a more pronounced appearance of yellow in the sclera. Ensuring that you are well-hydrated and maintaining a balanced diet can help mitigate this issue.

If this yellowing persists or is accompanied by other symptoms such as pain, vision changes, or increased sensitivity to light, it would be advisable to consult with an eye care professional. They can perform a thorough examination to rule out any underlying conditions, such as jaundice or other liver-related issues, and provide appropriate guidance.

In summary, the temporary yellowing of your eyes upon waking could be attributed to a variety of factors, including bilirubin accumulation, changes in blood flow, environmental irritants, or lifestyle factors. Since it resolves quickly, it may not be a cause for concern, but staying vigilant about your overall eye health and consulting a professional if symptoms persist is always a good practice.
