"It's very hard to fake, thus their presence can fairly reliably communicate one's overall health" ![]() "That's actually what makes limbal rings such a good cue to cardiovascular health, though," he says. Irritant dermatitis may cause rings to form around the eyes due to exposure to a chemical or other substance. He says that l imbal ring presence is contingent upon the clarity of the cornea - the outermost layer of the eye - which is partially predicted by the levels of phospholipids in the bloodstream. So is there anything we can do to enhance the visibility of our limbal rings? Not really, says Brown. Good genes, however, are less of a priority when judging someone as a potential long-term partner. Likewise, being able to spot a healthy woman who offers most competition would also be advantageous. These are called subconjunctival haemorrhages, and are caused by a small. Evolutionarily speaking, being able to recognize health clues that may hint at who has the best genes would be advantageous when choosing a short-term partner to mate with. Red blotches are often visible on the white of the eye after any form of eye surgery. This makes sense, say the authors, given reproduction is a more costly endeavor for women.
