Astaxanthin for Eye Health
ثبت نشده
چکیده
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. VDT’s are important because it forms the essential interface between an operator and computer to perform specific tasks. The problem acknowledged by the ophthalmic community is that habitual users of VDTs often lead to higher visual fatigue complaints. This phenomenon known as asthenopia prompted a large number of 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 the implemented improvements were only effective in 50% of sufferers. The possible explanations 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.
