Almost everyone these days is to use your computer for work or play. We spend a lot of time staring at computer screens and our people are experiencing vision problems. The eyestrain, blurred vision and headaches that often come with a computer called Computer Vision Syndrome (CVS).
Research suggests that up to 80% of computer users have vision problems or CVS. Many computer users do not associate their symptoms with the time they spend on the computer. Some assume that their headaches or eyestrain from work stress or tired, their eyes are expected part of their work. Computer glasses are special glasses designed for computer environments. They will make your computer time more productive and comfortable.
One of the causes of CVS is because the nature of text and graphics on a computer screen. The image on the monitor is equipped with pixels of light, are glowing dots are the brightest in their center with their luminance fall to zero to the edge of the bell-shaped fashion. Print on paper usually has a sharp, high contrast edges.
The human visual cortex has special cells that are very good at recognizing high contrast edges as printed on paper. These cells are an important basis for our visual perception system, because much of what we consider to be a “thing” in nature is shaped by high-contrast edges. Our eyes can lock in sharp contrast edges but have a difficult time maintaining focus accurately on pixel-created edge.
Looking at the computer screen, have our eyes have muscles attempt to focus on the distance and will remain to keep the forces as long as we are looking at the screen. In fact, what happens is concentrating efforts relaxes gradually and then return focus to the plane of the screen. Over time, the muscles fatigue and CVS symptoms occur
Computer Ergonomics :.
- Description in most offices is too bright for comfortable computing. If you can reduce lighting anything that will help. Watch the flash from doors, windows or reflected glare from the surface. If you wear glasses when working on the computer they should have a reflective coating on them.
- To minimize stress and eyestrain, the screen should be 20-30 inches away from your eyes. You should be looking slightly down at 15 degree angle. Use an adjustable chair with full Back Support
- In many offices, the air is dry due to the air conditioning and heater. When eyes become dry vision fades and eyes feel irritated. To make it worse, when we stare at the computer our rate of blinking slowly, wiped his eyes even more. Lubricating eye drops often help.
If you are experiencing eyestrain, blurred vision and headaches related to computer use, see an eye doctor. Why put up with eyestrain, blurred vision and headaches if you do not?
