- Spasms and involuntary eyelid twitching can be caused by stress, nutritional imbalance, or excessive caffeine consumption.
- Dark circles can be a sign of water retention.
The eyes do not only allow us to see. These are reflections of the internal state of the body. Clearly, these eyeballs tell us if we are in good health or if we are suffering from unsuspected health problems. Recently, several technologies have been developed to screen for a condition through the eye. This is the case of a smartphone application that was invented by scientists from the University of California in San Diego (United States). Thanks to a selfie, the latter measures the size of the patient’s pupil in order to detect symptoms of diseases or neurological disorders in their eyes.
But according to Barbara Pierscionek, professor at Anglia Ruskin University in England, it is possible to know if we have a pathology by looking and analyzing our eyes carefully. In an article published on The conversationthe researcher revealed the signs to observe and take seriously.
When the white of the eye turns yellow, it is usually jaundice or an abnormal liver function. This yellowing of the eye is improved by an excessive accumulation of bilirubin, namely a yellow pigment, in the blood.
The pupil no longer dilates properly
The pupil constricts and dilates instantly in light. When this pupillary reflex occurs slowly or late, it may be a sign of Alzheimer’s disease.
A red spot in the white of the eye
An ocular hemorrhage, that is, a blood vessel that has “popped” in the eye, can indicate high blood pressure, diabetes, or blood clotting disorders.
A white circle around the colored part of the eye
A clearer arc on the periphery of the cornea, called “arcus senilis”, may appear with age. But it can also be caused by a deposit of cholesterol. Clearly, this sign can be associated with excess cholesterol, but not imposed on hypercholesterolemia.
More and more protruding eyes
More bulging eyes can be the result of an infection, injury, inflammation, or tumor behind the eye. Another cause: a problem with the thyroid gland that causes swelling.
A bump on the eyelid
The chalazion, namely a red lump on the eyelid, is improved by the obstruction of a sebaceous gland.
