Many situations are considered sources of visual fatigue. This is not always the case.

WHAT CAUSES VISUAL FATIGUE?

Visual fatigue is linked to the focusing work that the eye must do so that the image projected on the retina is clear, regardless of the distance of the object being viewed. It therefore results in vision that becomes blurred when you use your near vision for too long. The closer the object, the greater the accommodation effort. By forcing accommodation, visual fatigue appears. In addition, as the accommodation capacity decreases with age, this problem becomes more common around the age of 40.

CAN STARING AT A SCREEN CAUSE VISUAL FATIGUE?

Yes, using a computer or watching television for a long time can indeed tire the eyes. But neither can cause a visual disorder (myopia, astigmatism, etc.).

IS DRY TEAR A CAUSE OF EYESTRAIGHTEEN?

Yes, eyestrain can be linked to a defect in tear secretion. Your eyes sting, they are red and irritated, a sensation of dry eye can appear. Working on a screen or reading reduces the frequency of blinking, thus causing dry eyes. Similarly, dry air, air conditioning, fans, smoking promote dry eyes and therefore eyestrain. Finally, the sun can also dry out the cornea and cause these fatigue phenomena.

Many situations are a source of eyestrain.

CAN POORLY FITTED GLASSES BE THE CAUSE OF EYESTRAIGHTEEN?

Yes, poorly fitted glasses and therefore an uncorrected or poorly corrected vision disorder cause visual fatigue. It is essential to check your eyesight in order to adjust the correction of your glasses or lenses.

HOW CAN THIS VISUAL FATIGUE BE TREATED?

Your glasses correction must be adapted if necessary. Orthoptic sessions can also easily correct this fatigue by re-educating the eyes. It is important to take breaks during the day, by closing your eyes for a few minutes every hour. You can also instill artificial tear drops in the event of dry tears. If you work on a computer, make sure that the screen is not lit by daylight. Choose its location accordingly in relation to windows.
After back pain, visual fatigue is the new illness of the century linked to the evolution of our lifestyle habits (computer, television, etc.). It can be easily relieved by the care you must give to your eyes.
