Eyestrain : Introduction , Sign and Symptoms , Causes , Risk Factors


Eyestrain may be a 
common condition that happens when your eyes get tired from intense use, like while driving long distances or watching computer screens and other digital devices.

Eyestrain can be annoying. But it always 
isn't serious and goes away once you rest your eyes or take other steps to scale back your eye discomfort. In some cases, signs and symptoms of eyestrain can indicate an underlying condition that needs treatment.



Eyestrain signs and symptoms include:


Ø  Sore, tired, burning or itching eyes

Ø  Watery or dry eyes

Ø  Blurred or double vision

Ø  Headache

Ø  Sore neck, shoulders or back

Ø  Increased sensitivity to light

Ø  Difficulty concentrating

Ø  Feeling that you cannot keep your eyes open



Common causes of eyestrain include:


Ø  Looking at digital device screens

Ø  Reading without pausing to rest your eyes

Ø  Driving long distances and doing other activities involving extended focus

Ø  Being exposed to bright light or glare

Ø  Straining to see in very dim light

Ø  Having an underlying eye problem, such as dry eyes or uncorrected vision (refractive error)

Ø  Being stressed or fatigued

Ø  Being exposed to dry moving air from a fan, heating or air-conditioning system


Computer and digital device use

Extended use of computers and other digital devices is one among 
the foremost common causes of eyestrain. The American Optometric Association calls this computer vision syndrome, or digital eyestrain. People who check out screens two or more hours during a row a day have the best risk of this condition.

Computer use strains eyes quite 
reading print material because people tend to:


Ø  Blink less while using computers (blinking is key to moistening the eyes)

Ø  View digital screens at less than ideal distances or angles

Ø  Use devices that have glare or reflection

Ø  Use devices with poor contrast between the text and the background

In some cases, an underlying eye problem, like 
ocular muscle imbalance or uncorrected vision, can cause or worsen computer eyestrain.

Some other factors which will 
make the condition worse include:


Ø  Glare on your screen

Ø  Poor posture

Ø  Setup of your computer workstation

Ø  Circulating air, such as from air conditioning or a nearby fan



Eyestrain doesn't have serious or long-term consequences, but it are often 
aggravating and unsightly . It can cause you to tired and reduce your ability to concentrate.
