Why do some people/children have very white sclera in the eye and others have more veiny or bloodshot sclera?

Normal variations: Each person will have different blood vessels in the conjunctiva, so some variation is normal. If your eyes are chronically red, however, it may be a sign of ocular inflammation, dry eye or other causes and may be treatable with drops. I'd suggest anyone with chronic red eyes to be examined.

Eye color varies: Eye 'whiteness' varies with race, genetics and particular eye issues.Sun damage frequently causes redness at the 3 and 9 o'clock positions on the eyes.Dryness also makes the eyes look more red.If no pain or discomfort, check it out in routine fashion.
