The most common causes of dilated pupils in adults are the use of eye drops. Such changes do not have negative consequences.
There are other reasons that cause dilated pupils:
- Aneurysm of the aorta.
- Intracranial bleeding, triggered by trauma.
- Development of a brain tumor.
- The difference in pressure on the eyes (one more, another less). The cause of this, as a rule, is glaucoma.
- Membrane infection, triggered by meningitis or encephalitis.
- Constant and prolonged headaches.
- Development of a tumor of the lymph node located in the upper region of the chest.
- Taking medications (Atropine, Scopolamine, Gomatropin and Adrenaline).
- Помните о том, что одним из основных факторов, affecting the size of the pupils, is a powerful release of adrenaline into the blood. In general, dilated pupils are an indicator of the internal state of a person. It is for this reason that during the operation the doctors constantly monitor the condition of the pupils of the patient, in order to diagnose the changes in time. When the patient is given a light anesthetic, his pupils are narrowed. If the anesthesia is deep, the pupils dilate.
- Скорее всего, известным фактором, вызывающим "Big pupils" is the use of drugs, alcoholic beverages or hallucinogenic drugs. Remember that even if a person still refuses to take drugs, the pupils no longer take on their former form and remain forever dilated.
In addition to medical indicators, there arenatural causes of dilated pupils. This happens when changing lighting. In the dark, the pupil expands. If its diameter is about 3-5 mm at rest, its size increases about one and a half times as a result of the reaction to darkness or twilight. At a person’s different ages, the pupil reacts differently. Young people are more adapted to the dark. In adulthood, the size of the icon is reduced.

As a rule, patients who have such a disease, in normal light, have dilated pupils. When the brightness of the light rises, the eyes may start to hurt. There are also problems in the absence of light at all. Such patients need to be extremely cautious during movements at night. They cannot see objects in full at night. This is especially dangerous for drivers.
The human body is undergoing changes duewith the influence of psychological factors. Eyes are no exception in this case. When a student, for example, experiences a strong emotional strain as a result of an exam, an upcoming test paper, or an unlearned class, his pupils dilate. Also, pupil dilation is observed as an adverse reaction to physical pain (sharp, sharp pain).
When does a person have an emotional state?sad, sad, upset, pupils, on the contrary, are narrowed. That is, emotions associated with a melancholic mood cause a decrease in their size. And their sharp splash - expansion.
