How to Get Rid of Dilated Pupils
The black center portion of the eye dilates in response to a number of situations which include a darkened room, brain injuries, and in response to certain medications. The ability to dilate or constrict the pupil of the eye is under the control of the central nervous system. Pupil width is typically a response to the amount of light present. In low light situations the pupil dilates to allow more light in aiding vision. When the light is very bright the pupil must constrict to protect the retina from damage. There are medications and certain medical conditions which also cause dilated pupils.

In getting rid of dilated pupils it is important to know what caused them. The dilated pupils or one dilated pupil could be a response to brain injury. Warning signs are often only one dilated pupil that does not react to bright light along with other neurologic symptoms such as weakness, altered mental status, and/or a change in speech or gait. In this setting medical care should be sought immediately.
Medications, even over the counter drugs, can also cause dilated pupils. It is true drugs such as marijuana and cocaine dilate pupils but prescription medications to control seizures and medications to treat attention deficit disorders will also increase the pupil diameter. Changing medications may be an option to get rid of the dilated pupils, especially if visual problems occur. Over the counter drugs for stomach upsets and motion sickness will cause dilated pupils. If these are the culprit new remedies should be found.
Irritation of the either the cornea or the conjunctiva, protective coverings of the eye, can cause dilated pupils. To decrease the irritation remove any foreign bodies such as contacts and apply soothing, moisturizing eye drops. If the irritation does not quickly abate reducing the amount of pupil dilation see a physician to treat any possible infection.
If no causes can be found there are still ways to get rid of dilated pupils. Medications can be used to constrict the pupils. Eye drops specifically for this purpose contain medications such as phenyephedrine and pilocarpine. Patients with glaucoma use these drops to constrict their pupils decreasing interocular pressure. Care must be taken with constricted pupils also. The decreased light will protect the eye but it will make night vision difficult. Always take care to use appropriate eye wear. Do not drive or operate machinery with impaired vision.
