Tired Eyes – What You Need to Know?
All of us have had tired eyes once in a while, some of us more often than that. In today’s day and age of digitization, with both work and recreation depending on staring at a bright screen, fatigue of the eyes is a complaint more common than ever before. Fatigue or tiredness of the eyes can lower your productivity, and make you generally feel unhealthy. Tired eyes, or eye strain, is not a disease per se, and usually does not require treatment. Tired eyes, which are sore and irritated, are often a sign of an underlying weakness of eyes, or of intense use.
This article will deal with the most common causes, and also the remedies for tired eyes.
What causes tiredness of eyes?
Any activity that requires intense eye use, without rest, can cause fatigue of the eyes. Some of the most common causes include:
- Staring at any screen device, be it a computer, smartphone, or game console, for extended periods: Your eyes have to work harder to focus on small words, held close to the face, and this condition is called Computer Vision Syndrome.
- Decreased rate of blinking: The standard blink rate is about 12 to 18 times a minute, but drops when reading, or focusing on a screen, to less than half its average It results in dry, tired, scratchy, red and burning eyes.
- Poor lighting: This increases the strain on the eyes, as they have to work harder to focus on the weak ambient light.
- Not enough sleep: Sleep results in a necessary, enforced rest which helps the eyes muscles relax. Lack of sleep results in tired, red and sore eyes.
- Uncorrected refractive error: If you have a refractive error and require glasses, either for near or distance, your eyes have to work much harder to enable you to see clearly. It increases the eye strain and may result in headaches, in addition to eye fatigue.
What are the associated symptoms?
The common signs and symptoms of eyestrain are as common as eye fatigue itself. These include:
