What are the symptoms of dry eyes?

Most cases of dry eye syndrome are caused by a small amount of tears. Patients with dry eye syndrome often feel that their eyes are very dry and tired, and may even have difficulty reading on the computer. Their eyes feel very dry and they may experience symptoms of itching and stinging.

Dry eyes are caused by a low amount of tears. People with dry eyes often complain that their eyes tire easily, making reading and watching television difficult. These difficulties occur because the frequency of blinking decreases significantly when the task requires concentration. When the blinking frequency is significantly reduced, the tear film evaporation time will be significantly prolonged. What are the symptoms of dry eyes? Let’s find out together.

The symptoms of dry eye syndrome are divided into the following types: tear deficiency dry eye syndrome, which means that the amount of tear secretion is reduced and the evaporation is too strong, which causes the normal tear film on the surface of the eye to dry up faster and cause dry eye syndrome.

The most common symptoms of dry eye syndrome are dryness and foreign body sensation in the eyes. Other symptoms include burning sensation, itching, photophobia, redness and pain, blurred vision, fatigue, and sticky secretions. If you have the above symptoms, you should carefully inquire about the medical history and find out the cause.

Symptoms of dry eye syndrome include: patients with dry eye syndrome experience dryness, foreign body sensation, pain, photophobia and burning sensation, itching, red eyes, visual fatigue, blurred vision, fluctuating vision, itching, stinging, dryness, discomfort, foreign body sensation, easy visual fatigue, heavy eyelids, irritability, and difficulty concentrating. Severe dry eyes can cause a significant decrease in vision, affecting work and life, and even leading to blindness.

The above symptoms of dry eyes are aggravated in hot and dry climates, as well as when exposed to certain chemicals, dust, smoke, and prolonged exposure to computer screens. In more severe cases, symptoms of dry eye may include the following: formation of greasy areas at the eyelid margins, seborrheic blepharitis or crusting. If it is removed, blood will seep out of the surface. The tear film thickness decreases and mucoid debris or fibrous secretions appear. The conjunctiva may become dull, thickened, edematous, hemorrhagic, sometimes covered with secretions, and in more severe cases the conjunctiva may become keratinized. When using fluorescein for corneal staining testing, dot-like aggregation will appear.

Clinical indicators that are often helpful in diagnosing dry eyes include tear break-up time, tear secretion tests, and diagnostic staining. If the above symptoms of dry eye are present, dry eye can still be diagnosed even if the objective examination is negative. On the contrary, even if the objective examination is positive, but the patient does not have the above symptoms, the diagnosis of dry eye should be made with extreme caution.
