You can observe how the eye of a cat look like under shades.It works the same way with humans. 2.Children are often required to have their pupil dilated before vision test, as their conditions are still not stable enough without dilated pupils. 3.Drug use. Certain medicines can cause the pupils to dilate. 4.Dilated pupils is also a symptom of autonomic neuropathy. 5.There may be damage in the muscles that control the pupils.

    Pupil is the opening in the central part of iris which is responsible for controlling light entering into eyes. So pupil dilates when the light is dim while it shrinks if the light is strong and bright. So in a dim environment, dilated pupils are very common and normal that you don't have to worry about it. People are likely to have dilated pupils if they saw something they are interested in. When people are nervous, panic, terrified, painful and happy, the pupils are dilated. It is a natural reaction of nervous system. It is normal. Don't worry. If you find the symptom persisting, you can take your child to see a doctor for sure.

    Well, generally speaking, there are also many factors, which can causes dilated pupils. For example, we can say that high blood pressure can cause dilated pupils. But for your child, I think there are some other reasons which can be possible. That is muscle tensions, which is the most common ones which can be related to dilated pupils in children. So you need to pay more attention to your child, when he go outside and play. And when dilated pupils occur, the black part of the eye will be bigger than normal one. And that can be annoying and painful. To treat it, you should make sure you wash the eyes frequently and apply cleansing eye drops to get rid of any foreign particles. Also, you can try some cool teabags and cucumbers under eyes. And that can be good.

    Dilated pupils in children are also quite common. There may be very many causes of dilated pupils but neurological problems are the most common cause of the same. Uneven dilated pupils may be a sign of a serious condition which may be life-threatening if not treated in time. Usually a dilated pupil is caused due to a stimulus to light, wherein the pupils constrict when light brightens and dilates when light dims. Pupils dilate to allow for more light to enter the eyes, so that one is able to see objects even in a poorly lit area. However, if one wants to know what causes dilated pupils other than the natural cause, one must be enlightened with the fact that pupils always dilated may have other causes. Emotions such as fear, anger, sexual orgasm and attraction may also fall under the category of naturally induced causes of dilated pupils. Dilated pupils ecstasy is also a cause of ecstasy and overexcitement that one may experience while having a strong libido. The basic reason cited behind the constant dilated pupils is the release of oxytocin. The opposite of dilated pupils is known as Miosis. Some of the other reasons for dilated pupils may include neuropathic disorders, trauma, medications and drugs, poisoning, any kind of injury or the spinal cord that may give rise to neurological problems.

    The pupil is the large black circle that is in the center of each eye. It widens and narrows naturally in response to changes in the light. Pupils become larger in dim light to let in more of the image and smaller in bright light to limit the amount of light that is received. Researchers at the American Council for Drug Education caution parents to watch for dilated pupils to tell if their children are using drugs. Illegal substance abuse can be spotted by dilated pupils in those who are using stimulants such as methamphetamines, cocaine and hallucinogens like mescaline and peyote. The drugs excite the central nervous system and mix signals from the brain, which also cause the euphoria associated with the drugs in addition to dilated pupils, increased heart rate, irrational behavior and mood swings.
