Symptoms of dry eye
It sounds contradictory that watery eyes are a symptom of dry eye, but it is.
This is because your body usually produces too many tears to help relieve these symptoms.
Causes [reflex surname tear secretion]. However, this is usually only used as a temporary remedy.
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.
BECAUSE THE TEAR FILM ON THE OCULAR SURFACE EVAPORATES TOO QUICKLY, MGD IS ASSOCIATED WITH DRY EYE.
It is also associated with eyelid problems in blepharitis.
Some studies have found that as much as 69% of the Asian population suffers from meibomian gland dysfunction, which cannot be ignored.
Association of allergies with dry eyes
Hong Kong weather is humid and hot, easy to appear different sensitivity, if children often eye marks, runny eyes, eye picking, etc., it may be eye sensitivity, it is recommended that parents observe the child's condition more to help the child avoid allergens, so as to avoid the child randomly twisting the eyes and causing corneal inflammation, affecting vision.
If symptoms persist, parents should take their children to the doctor, and the doctor will prescribe eye drops containing "antihistamine" or preservative-free moisturizing drops to relieve itching, while drops containing "mast cell stabilizers" can prevent eye sensitivity and recurrence.
