Causes Of Eye Miosis

Eye miosis refers to a condition in which the pupils of the eyes shrink to an abnormally small size despite being under normal lighting conditions. The condition is also commonly referred to as 'pinpoint pupils.' A small but important part of the eye, the pupils control the amount of light allowed to enter the eyes. They usually constrict and become smaller in bright light, an involuntary reflex that optimizes vision. However, this reflex can sometimes occur at inappropriate times and for various reasons.
