2. Myopia - A common cause of excessive blinking is myopia. It has been observed that these children experience watery eyes, headaches, blurry vision, and excessive blinking. 
3. Eye allergies - If your child blinks too much, has watery eyes, or has excessive discharge around the eyes, it could be an allergy.
4. Eye fatigue - It is commonly seen in children who spend prolonged periods watching television and using computers and other electronic devices. Reading in low light, spending excessive time on screens, and inadequate sleep can lead to fatigue.
5. Obsessive-Compulsive Disorder (OCD) is a mental disorder that can affect many children but often goes undiagnosed. This psychological condition can also lead to excessive blinking or facial tics.

Our tears are made up of water (water-based), oil (lipids), and mucus (mucin). There are two main forms of dry eye: dehydration and evaporation.

When a person suffers from the watery form of dry eye, the tear glands in the eye do not produce enough tear-like components.

IN EVAPORATION, IT IS CAUSED BY MEIBOMIAN GLAND DYSFUNCTION (MGD), IN WHICH THE OIL LAYER OF THE TEAR FILM IS INSUFFICIENT.

MGD AFFECTS MOST PEOPLE WITH DRY EYE.

MEIBOMIAN GLAND DYSFUNCTION (MGD) IS A BLOCKAGE OF THE MEIBOMIAN GLANDS SO THEY DON'T SECRETE ENOUGH OIL IN THE TEARS.
