Eye Strain Symptoms

Many people who use computers complain of eye strain. Any action that requires strong use of the eyes for an extended period of time or under difficult conditions such as driving a car for extended periods, reading, or working at the computer, can cause eye strain.

Eye Strain is known as “Asthenopia” into medical terms.

Tired eye is another term for what is mostly known as eyestrain – when eyes feel achy, weak, or heavy due to intense use. Eye strain not an eye disease, is a symptom. Eyestrain can create eye embarrassment and headaches, although it is uncommon and overrated as a cause of headache. Particularly headache connected with any function limiting activity.

Eyestrain is caused by improper focusing like nearsighted, farsighted or astigmatism and when the two eyes are not properly aligned. If you have any eye discomfort caused by looking at something for a long period of time then you are suffering eye strain.

Other signs and symptoms of Computer Vision Syndrome

  • Neck, shoulder or back pain
  • Overall body fatigue or tiredness

Eyestrain & Computer Vision Syndrome related issues

  • Eyestrain and Computer Vision Syndrome can significantly reduce productivity in the work place
  • Through excessive reading and computer work, eyestrain and Computer Vision Syndrome can impact your children’s vision
  • There is evidence to suggest that excessive reading or computer work can cause myopia

You might face any of these eye strain symptoms by any activity that requires intense use of the eyes for a prolonged time and these include extended periods of:

  • Computer work
  • Writing
  • Reading
  • Driving

While eye strain is a fairly common condition, you need to monitor your eye strain symptoms closely as they may be indicative of a more serious underlying condition.

Possible Conditions

Here is a list of some conditions that may be associated with your eye strain:

  • When you exhibit symptoms such as headache, tired and painful eyes and blurred vision, this can mean that the cornea and the lens of your eyes are not working together properly to focus images on the retina at the back of your eye. This then forces the small muscles of your eye to work harder, resulting in eye strain.
  • If you are experiencing headaches, those may be due to excessive squinting and overworking of your eye muscles to attain better focus in your vision.
  • When you exhibit symptoms like headache, that may be caused by internal pressure and swelling within the structures of the eye. The pain felt therein can be transmitted to other parts of the head.
  • Hyperopia, also called long-sightedness, occurs when the image you see is focused to a point behind your eye, instead of focusing it on the retina at the back of your eye.
  • Glaucoma is another condition that may be associated with your eye strain. It is a group of eye conditions that can damage the optic nerve or the nerve that carries visual information from your eyes to your brain.

You may not be able to change the duration that you’re in front of a computer at work, or the reasons that can cause eye strain but you can take steps to reduce it and usually it is not serious and goes away once you rest your eyes.
