Eye colour in sclera yellow-red

A yellowish tint in the sclera, especially since childhood, can be concerning, but if thorough liver function tests come back normal, it may not be linked to liver diseases. Long-lasting scleral discoloration like you’re describing can have multiple origins. Since your liver tests are normal, some non-hepatic factors might be considered. Genetics and racial factors can sometimes give a subtle yellow tint to the sclera. In addition, ocular surface conditions such as pinguecula or pterygium can cause localized yellowish areas, especially if there’s also some redness associated. These are usually benign growths originating in the conjunctiva due to long-term UV exposure or irritants. It’s good to think about whether you’ve had consistent exposure to the sun or environmental irritants, which might contribute to such changes. Sometimes, certain metabolic conditions or mild hemolytic processes can be underlying culprits, albeit rare. Double-checking bilirubin levels—direct and indirect—might give additional clarity. You mention no lifestyle habits like smoking or drinking, so those common contributing factors are already ruled out. Since this condition has been present since childhood, it’s likely not an urgent issue, but for peace of mind, having an eye doctor evaluate the front part of your eyes could provide more personalized insights. If there’s any change in color intensity or any new symptoms like vision trouble, definitely seek advice promptly. Regular use of sunglasses and protecting eyes from UV light can prevent further ocular damage if environmental factors are contributory. Keep an eye on any additional changes, but given the context, this may not necessitate treatment beyond protecting your eyes and monitoring the eyes for any new developments.
