Asthenopia (eye fatigue)

Myths:

Eye strain due to sustained near work cannot be helped.

Facts:

There are many ways eyestrain can be reduced naturally through proper ergonomics, taking regular breaks from the computer or reading, doing eye exercises, taking targeted supplements such as astaxanthin, lutein and black currant seed oil.

Overview:

Asthenopia is a word often used in the eye care profession to describe a collection of symptoms that can produce eye fatigue, red eyes, eye strain, pain in or around the eyes, blurred vision, headache and occasional double vision, usually brought on by prolonged close work.

Symptoms:

The symptoms of asthenopia include sensitivity to glare, headaches, sore eyes, and blurred vision. Standardized questionnaires that assess subjective eye fatigue find that symptoms are in most cases mild, but get progressively worse if the causes are not rectified.

Causes:

This phenomenon known as asthenopia has prompted many occupational safety studies. For example, epidemiological studies over the last decade revealed significant factors that contribute to eye fatigue. These studies, sometimes involving up to 6,000 sufferers identified the following causes:

• insufficient lighting,
• poor ergonomics and
• uncorrected vision.

Despite the new information, follow-up studies later showed that implemented improvements were only effective in 50% of sufferers. The possible explanation for this observation could be that other factors remained undiscovered, poor implementation of improvements, or visual work had become even more visually demanding. It is likely to be a combination of these factors so that current solutions are insufficient to reduce asthenopia.

More recently, the advances of information technology, software and electronics have led to the widespread use of screen based equipment or visual display terminals (VDT) especially at work or leisure, an essential interface. The problem acknowledged by the ophthalmic community is that habitual use of VDTs often leads to higher visual fatigue complaints.

Conventional Treatment:

Beside removal of the cause of eye fatigue, which is often not practical, there has been little progress toward relief of this growing problem other than setting up work stations properly, and possibly getting fitted for glasses to help reduce eyestrain.

The computer are the causes of eyestrain

More than half of all computer users experience eyestrain symptoms such as headaches, blurred vision and other symptoms associated with the use of computer screens. This is called "Computer Vision Syndrome". Visual stress from excessive close-up work may also cause complaints of general fatigue, reduced efficiency at work and higher error rates as the amount of time spent using computers increases.

We believe that the health of the eye depends on the well-being of one's entire body. Therefore, we provide recommendations for healing and preserving vision that encompass lifestyle, diet and nutritional products based on our analysis of peer review studies.
