The eyes are a complex mechanism responsible not only for visual perception. They show emotions, mood, state of health. The iris and pupil help in the diagnosis of certain pathological conditions.
Everyone has heard the phrase “glass eyes,” but not everyone knows what it means. So they say about a man who has no emotions. Such people are indifferent to everything that happens, devastated, removed.
Causes
Characterizing some people, ophthalmologists use the phrase “glass eyes”. It is commonly understood as a person suffering from alcohol or drug addiction. This clinical sign is observed in case of poisoning, the negative effects of opiates and other substances, as well as intoxication.
Usually in drug addicts the pupils are always significantly dilated or narrowed - this depends on the type of narcotic substance that he uses. Some of them are aware of a stable change in the state of the pupils, so they use eye drops to help hide their harmful dependence.
Glass eyes are a characteristic sign of addiction. The clinical condition manifests itself in conjunction with other pathologies: fussiness, sweating, impaired appetite, etc. If suddenly a loved one shows such symptoms, this may indicate a drug addiction.
Glass eyes may indicate an ophthalmic problem. Sometimes this term is called a change in color, transparency of the conjunctiva, cornea. Before the gaze, a veil may appear, which is also called glass eyes. In such situations, the help of an ophthalmologist is needed to help establish a diagnosis and identify the true cause of the change in vision.
Ophthalmic reasons
Glass eyes in humans can be observed with the following pathologies:
- Keratitis This is an inflammatory process in which the cornea and conjunctiva of the eye change. Keratitis can be viral, infectious, mechanical, allergic. Symptoms of the disease are manifested by clouding of the cornea, increased lacrimation, blepharospasm. Patients complain of a foreign body sensation in the eye.
- Conjunctivitis. Pathology is an inflammation of the mucous membrane of the eye. The disease is manifested by hyperemia of the mucous membrane, swelling, pain. Patients complain of sand in the eyes, photophobia, headaches.
- Corneal dystrophy. This group includes a number of diseases associated with genetic disorders without an inflammatory course. Dystrophies develop without any relationship with any pathology. During this process, all layers of the cornea are affected.
Shine in the eyes and state of mind
In ancient Egypt, women with brilliant eyes were considered very attractive. To achieve this effect, the Egyptians instilled lemon juice in their eyes. Later, representatives of the beautiful half of humanity began to drink several sips of alcohol to expand the pupils.
The reason for a person’s glass eyes can speak of his state of mind: joy or happiness. All this causes a manifestation of the natural shine of the eyes, which attracts attention.
Similar changes are manifested in pigment cells. It is they who determine the condition of a person and convey it with a sparkle in his eyes. The organs of vision are connected with the nervous system, and they show how a person reacts to what is happening. Even after death, people for some time remain the reaction of the iris to the light.
For a long time, scientists studied the phenomenon of glass eyes, the causes of which are mental states. They found that the brilliance is manifested not only with a sense of happiness, but also with severe depression.
People who are comfortable with life have a special radiance in their eyes. They often say about such people, "eyes shine with happiness."
During depression, people try to hide their tears. This leads to glare on the mucous membranes of the eyes.
Fatigue
A classic manifestation of shine in the eyes is fatigue. This effect is associated with prolonged eye strain: while reading, working with papers, a computer. Such a radiance is not a disease, but can lead to serious pathologies.
Perfect eyes
There are a number of signs by which beautiful and healthy eyes are determined. These include:
- A beautiful cut of the eyes. It should be perfect in relation to all traits of persons. Eyes and hollows must not be defective.
- Eyelids that completely close their eyes, but do not hang. They should well protect the eyes from negative factors.
- Iris located in the center relative to the protein of the eye.
- Clear and even color of the iris.
- Inner well-being reflected in the look.
As can be seen from the above, not always glass eyes indicate the presence of pathology or dependence on narcotic substances. This symptom can occur with fatigue, depression, prolonged work at the computer, with prolonged mental stress. All this leads to the appearance of a glass effect of the eyes.
