Asthenopia is a very broad and ill-defined concept related to limited vision.
It does not refer to a decrease in visual function, but encompasses all disorders and problems that arise in relation to the observation of objects up close.
This includes blurred vision, sporadic double vision, premature tiredness and the inability to maintain a uniformly clear image at a distance, which causes headaches and other eye-related pain.
The term “eye strain” is often used and usually means that the eyes are tired from heavy use. This is not a symptom of illness.
On the contrary, eye fatigue can be caused by prolonged observation of a book, a computer screen or even on the road while driving.
Visual tasks that require greater amounts of concentration, such as reading fine print or seeing in the dark, cause the eye muscles to tighten and strain too much.
This can also involve the muscles of the eyelids, face, temples and jaw as well. Excessive effort can lead to the development of pain and discomfort of those muscles.
Problems with asthenopia or eyestrain may be unavoidable, since long hours of eye use may be required for our work.
The light is a trigger factor of the very common visual fatigue, as in the case of looking at the monitor of a computer during long hours in a room with low light.
Given the fact that many people tend to blink less when performing computer tasks, the problem of eye fatigue is often aggravated by dry eye and dry eye symptoms.
The defects of the eyes themselves, such as refractive errors that require corrective lenses or the inability to make both eyes work together binocularly, can also produce symptoms of eye fatigue.
Symptoms of asthenopia (eye strain) may include:
- Visual fatigue
- Eye pain
- Blurry vision
- Double vision
- Burning eyes
- Crying eyes
- Dry eyes
- Neck Pain
- Photophobia (sensitivity to light)
Eye strain is a very common and frequent problem, since most occupations require constant use of the computer.
The popularity of smartphones, which have bright screens, have also contributed to this problem.
