What can your eyes reveal about your health? Quite a lot – and some things you can see simply by looking in the mirror.
Dark eyes: Considered more trustworthy
Researchers to analyze the correlation between eye color and facial features, discovered that men with dark eyes tend to have more additional trustworthy traits than those with light eyes (such as bigger mouths, broader chins, and bigger eyes and features that mirror how faces naturally express happiness.)
Gray ring around the cornea
Gray isn’t just for hair. Some people develop a gray ring around the edge of the cornea. The ring, which doctors call arcus senilis, often goes hand in hand with high cholesterol and triglycerides – and an increased risk for heart attack and stroke. Anyone who has the condition should have a blood test to check for elevated blood lipids – especially people under age 60.
Less likely to have vitiligo . Researchers identified 13 genes linked to a predisposition to vitiligo. They found that people with the disease were significantly less likely to have blue or gray eyes than those without it. Of the vitiligo patients, 43 percent had dark eyes, 30 percent had green or hazel eyes, and 27 percent had blue or gray eyes. Vitiligo patients are at higher risk for other autoimmune diseases such as lupus, type 1 diabetes, and thyroid disease.
This is a cataract – a clouding of the lens inside the eye. The condition, which can be corrected with surgery, is most common in older people. Cataracts that arise in younger people can have a variety of causes, including tumors and diabetes, as well as side effects from certain medications.
Pupil abnormalities. The pupils of healthy people are usually (but not always) symmetrical. They’re usually of the same size, and they usually show the same reaction upon exposure to light. If one pupil is bigger than the other, or if one pupil shrinks less, or more slowly, on exposure to light, there could be an underlying medical problem. Possibilities include stroke, brain or optic nerve tumor, brain aneurysm, syphilis, and multiple sclerosis.
Bloody eye. The eye’s transparent outer layer, called the conjunctiva, is nourished by numerous tiny blood vessels. If these burst, blood may pool on the white of the eye (sclera). A subconjunctival hemorrhage, as it is known among doctors, can be caused by a blow to the eye but in most cases has no obvious cause. In rare instances, a subconjunctival hemorrhage can be a sign of severe high blood pressure or a platelet disorder, which can interfere with clotting, Williams tells WebMD.
Bulging eyes. Though prominent eyes may simply be a family trait, eyes that appear to bulge may be evidence of thyroid disease. Abnormal levels of thyroid hormone cause tissues surrounding the eye to swell, making it appear that the eye is bulging.
Different colored eyes. Also called heterochromia iridis, this condition is usually inherited. A change in color may be due to bleeding, a foreign body in the eye, glaucoma, inflammation in the eye or other conditions such as Waardenburg syndrome or neurofibromatosis.
