Preventive treatment measures can and should be taken.
Hours spent staring at a computer screen adds to the discomfort and symptoms of CVS. As mentioned earlier, daily moist heat compressing alone is not enough to manage Computer Vision Syndrome. When using a moist heat compress it is important to use a product that is approved and safe to use repeatedly.īy using a daily moist heat compress, it prevents the blockage of the meibomian glands and help stimulate the glands to produce more of the essential oily tears. It’s important these glands are kept healthy-overtime, if the glands become blocked, they may atrophy or stop functioning all together.Ģ. This patented technology has been successful because of its consistent moist heat on the eye and surrounding area. One very effective treatment that has proven to relieve symptoms of CVS is the “ Tranquileyes Goggle” manufactured by Eyeco. A warm facecloth, poor quality plastic gel packs, or tea bags are inadequate substitutes and may cause overheating of the eyes as well as infections. The compress needs to maintain a constant 40 degree temperature for 10 minutes and allow for delivery of moisture). The good news is that we can manage the effects of dry eye syndrome a few different ways, one being with daily moist heat compressing. How can the effects of Computer Vision Syndrome be managed and how can its effects be treated?ġ. As technology progresses we are likely to see an increase in the use of electronic screens and therefore a rise in eye. “DEWS” study concluded that the major component to CVS is dry eye caused by prolonged exposure to computer screens. This compounds and starves the cornea of oxygen.The U.S. This indicates that we “stare” when using electronic devices and leads to less blinking, creating far less tear production and decreased oxygen for the surface tissue. The blinks may be less than 7 when using smaller devices such as cell phones. Tsubota in the New England Journal of Medicine reports an average of 22 blinks per minute will decrease to an average of only 7 blinks per minute, when using an electronic device. These very important oily tears then absorb oxygen from air and become hyper-oxygenated which in turn allow oxygen to absorb directly into the surface cells of the eye.Ī study done by Dr. When the top lid comes down (blink), it grabs these oily tears and spreads it evenly over the entire surface of the eye. This causes an oily tear to build up in small layer on the bottom lid (tear meniscus). This action of blinking creates the exact amount of force needed to push on the small meibomian glands embedded in the eyelid margins. We normally blink approximately 22 times per minute. The tear film is critical in feeding oxygen to the surface corneal tissue. To understand why looking at computer screens can lead to CVS, it is important to know why we blink and why we produce tears. The level of discomfort increases with more time spent on electronic devices, and tends to be worse with smaller hand-held devices (i.e. Blurry vision (especially intermittent blurry vision).
The American Optometric Association describes CVS as a group of vision- related problems that result from prolonged computer, tablet, e-reader and cell phone use. It is estimated to affect 70-90% of Canadians. This has led to an increase in a condition referred to as “Computer Vision Syndrome” or CVS. This means that Canadians spend more time looking at computer screens than any other country in the world. A study done by Ipsos Reid for Google found that Canadians spend up to 7.9 hours per day in front of computer devices. Computers, in all their forms seem, to be the “go to” for much of our communication, research & learning, leisure activity, and not to mention our work places. It is without doubt, that over the last 10 years, there has been a dramatic increase in the amount of time we spend looking at electronic devices.
