Causes of different pupils in adults

Among many diseases and deviations from the norm, allocated in ophthalmology today, a certain place is occupied by such phenomenon as anisocoria. This medical term indicates that a person has an uneven eyeball size.

It is because of light that the pupils increase or decrease, because in the dark they become smaller, and conversely, when a bright stream hits them, there is a noticeable increase.

Experts believe that with a slight difference in the size of the pupils, it is not worthwhile to sound an alarm. If the difference is not noticeable and is not evident, this is read by a normal state, in the case of an increase in the tolerable limits, it is necessary to undergo an examination with an ophthalmologist. The permissible norm can vary within one millimeter.
