Dry Eye Symtoms
Forty percent of Americans suffer from occasional dry eye – a common condition in which the tear ducts make insufficient tears for lubricating and nourishing the eye. Normally, the eye constantly bathes itself in tears. It may not sound logical that dry eye would cause excess tearing, but think of it as the eye’s response to discomfort. If the tears responsible for maintaining lubrication do not keep the eye wet enough, the eye becomes irritated. In addition to providing lubrication for the eye, tears reduce the risk of eye infection, wash away foreign matter in the eye, and keep the surface of the eyes smooth and clear.
Dry eye symptoms include:
Irritated, gritty, scratchy, or burning eyes
Feeling of a foreign particle in the eye
Redness in the eye
What is MPOD Macular pigment is comprised of Zeaxanthin and Lutein, which are found in the center of the macula (fovea) at a natural 2:1 ratio. MPOD (Macular Pigment Optical Density) is important for three specific reasons: 1. Low macular pigment is a key risk factor for Age-related Macular Degeneration (AMD), the leading cause of significant vision loss over age 55 2. Macular pigment absorbs harmful blue light, protecting the photo-receptors from damage 3. Macular pigment improves visual performance, including:
How big is the problem
Eye injuries account for 8% of workplace injuries and around 50,000 incidents each year. More than half of all the eye injuries suffered in Australia are workplace related.
Not surprisingly, the majority occur in industries such as construction, mining, agriculture, forestry and fishing. It's a big issue that costs Australian businesses around $60 million a year, not to mention the pain and distress to the sufferers themselves.
What about general eye strain
Computer Vision Syndrome is now a big problem. Regular PC use can lead to repetitive strain issues for eyes just as much as typing can affect the wrists and arms. The symptoms include tiredness, headaches and dry or gritty eye sensations, all of which can be distracting, disrupt work and lead to reduced performance.
It's estimated that taking eye tests and adopting appropriate vision correction can reduce errors and increase productivity by up to 25% for workers employed in moderate levels of visual processing.
