Medically speaking the dilation of the pupils is known as mydriasis. It is normal in conditions where there is a low amount of light supply and it happens in order to allow more light to be able to reach the retina.
The muscles that are in the iris are in charge of the size of the pupil. The pupil is what determines how much light will be able to enter the eye. As in lighter environments the pupil usually contracts to prevent too much light from entering the eyes and in darker ones the opposite thing happens and the pupil dilates in order to let more light get into the eye.
But if the pupils are dilated due to an abnormal or artificial reason, they will remain dilated even in lighter conditions. Brain injuries, strong medications and drugs are one of the main artificial reasons for the pupils to dilate. A dilated pupil only in one of the eyes may also appear as a sign of a brain injury or other more serious conditions that can cause pressure within the carnial cavity.
Other causes of dilated pupils may also be:
*Low ambient light
*Motion sickness medications
*Attraction to a person or an object
Mood and attraction are one of the most common natural reasons for dilated pupils. Changes in the size of the pupil are an involuntary body reaction that happens when we are looking at a person, we are affectionate for or love. It is the same with objects too. The pupils can also dilate when a person is paying attention, closely looking at, inspecting or listening to another person.
Are dilated pupils dangerous and should you be worried about them?
Temporary dilated pupils are usually harmless and nothing to worry about. But if it is something that constantly happens or you are taking certain medications and this causes your pupils to stay dilated for a long period of time it is better to contact a professional and get your eyes properly checked!
If one pupil appears more dilated than the other or you start experiencing any additional discomfort such as headaches and general confusion and misbalance, it could be a symptom of a more serious underlying problem.
Make sure to contact a doctor if you start experiencing any constant discomfort and get your regular check-ups in order to prevent more serious problems from developing!
