The human eye is an organ that reacts to light and has several purposes. As a conscious sense organ, our eyes let us see. The human eye can distinguish about 10 million colours.

Tired eyes.

In our modern lives, our eyes come under tremendous strain from work or studies, so it is not unusual for people to have tired and strained eyes.

The significant increase of amount of time we spend looking at the computer screen at work, in school and at home has led to an increase of a condition called VDT Syndrome, or computer-related syndrome. Symptoms of VDT include strains and aches of the elbows, arms, shoulders hands, wrists, fingers and of course the eyes.

Some symptoms of strained eyes:

  • Dry eyes, aching eyes and hyperemia (blood shot eyes)
  • Difficulty in focusing
  • Foreign body sensations
  • Headache and stiff neck
  • Frustration and lost of motivation

Mechanism of eyestrain

Asthenopia or eye strain is a condition with symptoms such as fatigue, pain in or around the eyes, blurred vision, headache and occasional double vision. Symptoms often occur after reading, computer work, or other close activities that involve tedious visual tasks.

A visually intense task, such as continuously focusing on a computer monitor, the ciliary muscle tightens. This can cause the eyes to get irritated and uncomfortable. Giving the eyes a chance to focus on a distant object at least once an hour usually alleviates the problem.

Conventional CRT computer monitors or a CRT television can cause similar problems because the image has a visible flicker. Aging CRTs also often go slightly out of focus, and this can cause eye strain. LCD and LED monitors and TVs do not go out of focus and are less susceptible to visible flicker.



Frequent resting of eyes. Prolonged concentration on the computer monitor or a book can easily cause eye strain. As a guideline, you should always rest your eyes for 10 minutes for every hour you spend on the computer. Try massaging gently around the eyelids, or focus on a distant object or trees.

Lighting and posture. Eyes get tired more easily under dark or inadequate lighting. In addition, bad posture while working on the computer will also give you shoulder and neck aches, so always work under bright lighting and be seated properly.

Eye glasses and contact lenses. For people with myopia, astigmatism, farsightedness, eyestrain will become worse if your prescription glasses are not made properly or if the glasses are ill-fitting. Always see a reputable and qualified ophthalmologist to keep your conditions in check.

Care of tired eyes. Vitamin B. If you have a deficiency in Vitamin B, eye problems could develop. Lack of Vitamin B2 could cause redness, irritations and light sensitivity. Vitmain B1 deficiency can cause weakened eye muscles while lack of Vitamin B12 can cause loss of vision or double vision. Intake of Vitamin B-complex supplements may help to alleviate or prevent these problems.

Eye drops. To improve symptoms of eye irritation and fatigue, eye drops are recommended, especially those that are formulated with Vitamins B6 and B12.
