You may find it annoying to see your child blinking excessively, but most of the time this behavior is not caused by anything serious. Ask your child if she is experiencing any other symptoms, but do not dwell on her blinking, suggests FamilyDoctor.org. Drawing attention to the matter may make it more prevalent.
Tics are repeated muscle spasms, explains Medline Plus. If your child has a tic, he can not control the movements. Some children experience facial tics, which can include excessive blinking. This condition is common during childhood, and may be caused by stress, certain medications or a chronic motor tic disorder. Rarely, facial tics may be caused by Tourette's Syndrome, a condition that usually starts between the ages of 3 and 10, according to FamilyDoctor.org. Most of the time, tics go away by adulthood without treatment. If you think that your child may have a tic disorder, talk to his doctor.
If your child is nearsighted, it means that she has trouble seeing faraway objects. She may squint, rub her eyes often or complain of blurry vision or headaches. In some cases, nearsightedness causes watering of the eyes, which may lead to excessive blinking, says MayoClinic.com If you think that your child may be nearsighted or that she has any other vision problems, take her to see an optometrist for a vision exam. Her pediatrician can also check her vision during routine office visits.
The American Optometric Association describes blepharitis as an inflammation of the eyelids. It causes redness, itching, irritation and scales on the eyelids. The irritation and inflammation may cause your child to blink his eyes excessively. The condition may be caused by dandruff or a bacterial infection. Washing his face frequently and applying warm compresses to the area may be enough to treat blepharitis, but if your child has a bacterial infection, his doctor may prescribe antibiotics.
If your child is suffering from eye strain, she may blink often, complain that her eyes are sore, itchy or burning, and suffer from a sore back, neck or shoulders. MayoClinic.com states that common causes of eye strain include using a computer or reading for an extended period of time, straining to see in dim light or being exposed to very bright light. Help your child remember to read in good light, to avoid watching television in the dark and to take frequent breaks when working on a computer. If excessive blinking persists or if your child develops a persistent headache or a change in vision, take her to the doctor.
