The inner sclera of my eye has a yellow/orange tint to it. however, its only visible when i pull back my eyelids to examine it. if im looking directly at myself in the mirror, my sclera looks white. should i be concerned about this?

Since the entire sclera isn't yellow you don't have jaundice which is a serious health issue. You may have an early pterygium which is caused by wind & sun exposure. A physician or ophthalmologist can examine & advise you

This is almost certainly not an immediate emergency but need to be evaluated. While this could be a tumor (lymphoid, etc.), it could also be related to jaundice, fat prolapse, etc.
