Visual Fatigue Syndrome (VFS) is caused by focusing on objects, such as computers, that are 1 to 3 feet away for extended periods of time.
The symptoms of VFS are not only bothersome, they can also be painful, reduce the enjoyment of your day and reduce the quality of your work.
Working on tasks up-close causes your eyes to drift outward, forcing your eyes to constantly work to turn the eyes back in. This process often leads to a number of symptoms like headaches, blurred vision, eye strain, double vision, burning and tearing.
When the eye focuses on a fixed target, the resulting accommodation is not constant. It varies around an average value, like with an auto-focus camera. These variations are called accommodative micro-fluctuations; they are imperceptible and uncontrollable.
When the eyes get tired, these micro-fluctuations practically disappear, which shows that the accommodation system has greater difficulty sustaining its effort. These micro-fluctuations provide the best objective evidence of visual fatigue.
Anti-Fatigue lenses help to restore the micro-fluctuations and retain the balance of the accommodative system, for fatigue-free vision.
Visual fatigue comes from many factors causing discomfort for your eyes. In your every day life, you are dealing with various devices both at work and in your personal life: computer, Smartphone, tablet PC, TV, etc.
Your life is busy and stressful and most likely surrounded by artificial lightening and a polluted environment. At the end of your day, your eyes may be hurting you They may seem heavy and your vision may be blurred, so your eyes will make every effort to adapt.
Common symptoms of VFS are:
✓ Dry eyes
✓ Sensitivity to light
✓ Neck pain
✓ Blurred vision
✓ Loss of productivity
✓ Decreased vision at night.
The common symptoms are by no means all inclusive.
These are just a few of the symptoms many suffer after long hours on the computer or by participating in "close-up" activities like working or focusing on small devices, playing an instrument sewing or reading.
Since most bifocal lenses and progressive lenses are not truly design for computer work, people tend to adjust their posture which may result in back or neck pain.
Remember, Anti-Fatigue Lenses can only be prescribed by a doctor, so if you have symptoms, contact us for an eye exam.
