Blinking is a perfectly normal, semi-autonomic bodily function. It is your body’s way of keeping your eyes well-lubricated as it promotes proper distribution of tears on the surface of your cornea. Blinking takes about 400 milliseconds. As such, a blink should hardly be felt. So what’s the deal when your child complains of a twinge of pain when they blink?
Today’s article from your child’s eye doctor at Myopia Institute sheds light on the leading possible causes for pain when blinking.
Due to their fragile nature, your eyes are prone to injuries. Small particles and debris can get into your eyes and lead to abrasions. Any type of ocular trauma such as suffering a blow to the eye can cause pain when blinking. You can also injure your eyes via excessive and vigorous rubbing.
You can also suffer from burns due to overexposure to ultraviolet rays or from contact with chemical substances such as cleaning products, vinegar, laundry detergents and pepper spray. Should your eyes come in contact with any of these products, immediately apply basic first aid then consult your optometrist.
Certain infections such as conjunctivitis, styes and tear duct infections can cause parts of your eyes to swell, thus making it difficult and painful to blink. Conjunctivitis affects the conjunctiva, resulting in swollen blood vessels. Most styes, on the other hand, are caused by a bacteria called Staphylococcus aureus. This particular infection causes your eyelids to swell. Tear duct infections cause pain in the corner of the eye.
Dry Eye Syndrome
Dry eye syndrome is characterized by impaired tear-producing glands. Patients with dry eye syndrome often find it difficult and painful to blink. Conditions such as aging, arid climate and certain medications tend to aggravate this particular disorder. Not blinking enough can also cause or aggravate dry eye syndrome.
Should you or your child encounter unusual pain when blinking, it’s imperative to see your eye doctor immediately. Myopia Institute specializes in pediatric myopia control. You may contact us at (301) 363-0060. We work with patients in Dallas, TX.
