Eye Fatigue Causes And Treatment

Eye Fatigue Causes And Treatment

If you have been looking at the bright light or staying in a place that is too dark for a long time, it will make your eyes feel tired. If you stare at your computer, smartphone, or game console for a long time, your eyes may become dry and stinging easily. These are all because of visual fatigue. So, do you know the causes, symptoms, and treatment of asthenopia?

The cause of visual fatigue

When looking at distant objects, emmetropia can form a clear image on the retina without any effort. In this case, even if you look for a long time, your eyes will not be tired. But when we look at close objects, in order to keep the image of the object clear, we must use the adjustment power of the eyes. At the same time, the collective power must be used to make both eyes look at the same object. When the power of adjustment or collection is used excessively, visual fatigue will occur. When the eye fatigue accumulates to a certain level, the symptoms of asthenopia will break out.

Visual Fatigue Symptoms

There are many symptoms of visual fatigue, such as sore or irritated eyes, dry eyes, blurred vision, headache, dizziness, increased sensitivity to light, and other organ reactions.

These symptoms will reduce your productivity. If you stay awake for a long time to work, it will make the problem worse. Sleep provides the necessary nutrients for your eyes. However, lack of sleep can cause repeated eye irritation.

Among them, headache is the most common symptom of asthenopia. Its attack range can be confined to the eye area, it may extend to the entire head, and sometimes it can also develop to the neck and shoulders.



How to prevent and treat asthenopia?

At present, most people who use computers and mobile phones for a long time suffer from visual fatigue. As work and entertainment are done on computers and mobile phones, more and more adults accumulate a large number of factors of visual fatigue unknowingly, but they can't stop at all. The visual fatigue treatment can help us reduce the symptom.

1. 20-20-20 Rule

What is the 20-20-20 Rule? Every 20 minutes, take your eyes off of your screen and look at something 20 feet away for at least 20 seconds. This will help eliminate the symptoms of visual fatigue.

2. Use two pairs of glasses alternately

Whether you are driving a car, riding a bike, or walking, you need a clear vision. So at this time, we need a pair of correction glasses to ensure our good vision. While at the company, if you need to use the computer all the time, you can wear a pair of blue light blocking glasses according to the optometrist's recommendation. In this case, the accumulation of visual fatigue can be appropriately reduced, but it is still recommended to have a rest appropriately.

3. Use anti-fatigue lenses

The anti-fatigue lens is made according to the principle of autofocus for human eyes to see far and near. When the eyes look at things at different distances, their adjustment and collective powers change in different ways. Single focus glasses only provide one degree, while anti-fatigue lenses will automatically adjust the visual balance according to the user's eye environment, reducing the production of visual fatigue.

It can not only meet the requirements for clear vision when walking or driving. At the same time, when looking at the computer in the office, the anti-fatigue lens with blue light blocking coating can be used for office work comfortably.

The application of electronic products has gradually become common in recent years, and the phenomenon of visual fatigue is more and more. For now, the best product against asthenopia is the anti-fatigue lens. As for how to choose the correct anti-fatigue lens, you need to go to a professional optician.
