The pupils of your eyes tend to grow bigger or smaller depending on the brightness or dimness of the light around you. The iris, or the colored area of your eyes that surrounds the pupils, controls their size. However, there are instances when they stay dilated despite changes in the light’s intensity. This is called mydriasis, and it is caused by numerous factors. Read on as eye doctors from your local eye care optical center explain this further.
Mydriasis occurs mostly through non-physiological causes. One of them is the use of medication. Intake of certain medicines such as antihistamines, decongestants and those that prevent motion sickness, nausea and seizures can affect the muscles that control the pupils.
Another cause is the use of illegal recreational drugs. Amphetamines, cocaine, lysergic acid (LSD) and MDMA (“ecstasy”) are known to dilate the pupils and slow down your reaction to light.
Injury to the eye can likewise cause pupil dilation. A small foreign object that penetrates the eye can damage the iris, resulting in that eye’s pupil to be irregularly shaped. Trauma to the head, or suffering a stroke or a tumor can affect how your pupils react to light.
Dealing With Dilated Pupils
Suffering a head injury would require immediate medical attention, especially if there is apparent dilation in one or both pupils. The same can be said for any symptoms of stroke, like dizziness, confusion and inability to maintain balance. You must also call your physician for advice if your pupils dilate after ingesting certain medications.
Otherwise, call your eye doctor. It is possible that you may be sensitive to sunlight for this reason. You may be given prescription eyeglasses designed to darken your outdoor surroundings during daylight or reduce glare for better comfort.
Apart from eyeglasses, you may be prescribed prosthetic contact lenses that are custom-made to imitate normal-sized pupils. While they are worn to improve the appearance of your eyes, they are also capable of minimizing your sensitivity to light.
