What does it mean by dilated eyes?
The muscles in the coloured area of the eyes, also known as the iris, control pupil size. Therefore, the pupils can get bigger or smaller according to the surrounding areas. In bright light, the pupils get smaller to reduce the entry of light; in dark areas, they enlarge to allow more light to enter. However, if the pupil of the eye does not reduce in bright light or expand in the dark, it can be understood that there are some issues with the pupil. Such a condition is known as Mydriasis, wherein the pupil does not respond to light correctly.
Although many people are born with pupils of somewhat variating sizes, their eyes can react to light normally. Therefore, dilated pupils might not be an issue, but if it does not return to normal, the affected individual could suffer from Mydriasis.
