Symptoms of mild dry eyes

summary

Dry eye is a disease of tear film and ocular surface damage caused by a variety of reasons. It can lead to eye discomfort, visual impairment and tear film instability, sneaking damage to the ocular surface, accompanied by high tear osmolality and inflammation. Let's talk about the symptoms of mild dry eyes.

Symptoms of mild dry eyes

The common symptoms of dry eye are dry eyes and foreign body sensation. Other symptoms of dry eye include burning sensation, itching sensation, photophobia, redness and pain, blurred vision, general fatigue, sticky filamentous secretion, etc. If you have the above symptoms, you should carefully ask the history, looking for the cause. For Severe Xerophthalmia, ask if there is xerostomia and arthralgia to exclude SS.

The symptoms of dry eye vary greatly among individuals. Most patients complained of foreign body sensation, burning sensation and general eye discomfort. These discomfort are typically described as scratching, dry eyes, pain, grit, tingling or burning. These discomfort are often evidence of dry eye, because the surface of the cornea is covered with sensory nerve endings. A considerable proportion of patients have photophobia, intermittent blurring or other vision problems.

Insufficient lacrimal secretion of lacrimal gland in aqueous layer is the most common cause of dry eye angle; Congenital absence of lacrimal gland, aging of lacrimal gland, dysfunction of lacrimal gland, or some autoimmune diseases cause lacrimal gland inflammation, trauma, infection and autonomic nervous dysfunction. Long term use of some eye drops (such as stopping the diagnosis of some drugs for fatigue glaucoma) or taking some drugs (such as some high blood pressure drugs, sedatives, etc.) can cause lacrimal secretion insufficiency; As for wearing contact lenses easily for a long time, because of reducing the sensitivity of cornea, sometimes it will also affect the secretion of tears every time.

matters needing attention

1. Blink more. Blinking is a kind of protective nerve reflex action. The tear layer can make the tears evenly spread on the surface of cornea and conjunctiva to keep moist but not dry. Once the number of blinks is reduced, the amount of tears will be reduced directly, and the tear film exposed to the air will evaporate quickly, losing the protection of the eyeball. When using your eyes for a long time, such as operating the computer, driving, reading, etc., remind yourself not to be too focused and spend some time blinking. Most people blink every five seconds, about 20 times a minute. 2. Pay attention to eye hygiene. Pay attention to eye hygiene, wash hands frequently, don't rub your eyes with your hands, take a rest for about an hour with your eyes, close your eyes and look into the distance. For patients with oily secretions, debris and shedding on eyelids, attention should be paid to keep eyelids clean. 3. Those who use computer for a long time can try to wear German Hello glasses, such as hello anti blue light glasses, to reduce the chronic light damage of blue light to retina.
