What is Eyestrain?

Asthenopia is a common ophthalmological disease. It causes dry eyes, astringent eyes, sore eyes, blurred vision and even vision loss that directly affect people's work and life. Eye fatigue is mainly caused by people's constant attention to the screens of electronic products such as televisions, computers, or mobile phones. The number of eye blinks decreases, resulting in a corresponding reduction in tear secretion, and the flashing screen strongly stimulates the eyes. Eye fatigue can also cause and aggravate various eye diseases. The best way to relieve eye fatigue is to rest your eyes.

Causes of visual fatigue and common diseases

1. Eye refractive abnormality

When suffering from farsightedness, nearsightedness, astigmatism, and spectacles, when you look far and near you need to use a lot of adjustment power to make the eyes overworked.

2. Excessive collection of eyes

When myopia is uncorrected, it may cause excessive collection due to the reading distance being too close. A vicious cycle occurs so that eye fatigue occurs. Constantly changing focus: When astigmatism, when the imaging can not be at a point, you need to use the adjustment effect of the ciliary muscle in the eye to constantly change the focus and use the adjustment excessively. Fatigue of the ciliary muscle will cause corresponding neural pain.

3. Eye diseases

Corneal cloudiness, lens opacity, and other unclear vision caused by eye diseases can also easily cause eye fatigue.

4. Eye development abnormalities

If the interpupillary distance between the two eyes is large, it is difficult to gather the two eyes, and it is easy to cause eye fatigue.

5. Physical and living factors

For example, lack of exercise, malnutrition, frequent insomnia, excessive alcohol and tobacco, and inattention to eye hygiene are all prone to eye fatigue.

6. Age factor

For people over 40 years of age, eyes begin to age, but they are not equipped with reading glasses in time, which is prone to eye fatigue.

7. Environmental factors

Inadequate lighting in the work or study area can cause eye strain and excessive use of accommodation.

Differential diagnosis of visual fatigue

Dry eyes

The so-called "dry eye syndrome" refers to a symptom in which tiny scars appear on the surface of the eye due to a decrease in tears or a decline in lacrimal gland function.

2. Eye pain

Patients with refractive errors have symptoms such as visual fatigue, eye pain, and inability to read.

Visual fatigue check

Ophthalmology checks for eye diseases such as hyperopia, nearsightedness, astigmatism, and glaucoma.

Asthenopia Treatment Principles

Treatment of visual fatigue

The principle of the treatment of visual fatigue is to treat the cause first ^[1] , eliminate the cause, and then perform symptomatic treatment.

Including drug treatment and non-drug treatment

Drug treatment : ^[1]

Treatment for the cause: Drugs that improve the function of eye regulation: Aescin Digitalis Eye Drops ^[1] , which acts on the ciliary muscle, improves the function of the eye by enhancing the function of the ciliary muscle and increasing blood flow of the ciliary muscle ^[1] .

Artificial tears to treat visual fatigue ^[1] .

Non-drug treatment:

Mainly refers to some physical treatments such as haze, distant view and eye exercises, etc. The main purpose of non-drug treatment is to improve the circulation around the eye and play an auxiliary role in the treatment of visual fatigue. In addition, reasonable suggestions can be given to patients' living habits, diet, lifestyle, workload and physical exercise ^[1] .
