Computer vision syndrome (CVS), also called digital eyestrain, is an eye condition that is caused by prolonged computer use. Using a computer or other digital devices for a long time can cause eye irritation or blurred vision.
Between 50 to 90 percent of people who use computers all day experience some form of eyestrain. The strain is caused by the blue light that is emitted from the screen. The eyes work constantly to focus and refocus on the monitor, causing strain.
Several symptoms can indicate that you are suffering from CVS. The symptoms include double or blurred vision, dry or red eyes, neck and back pain, and headaches. The symptoms differ depending on everyone.
People who have an existing eye condition may experience more severe symptoms. The type and severity of symptoms will also depend on the amount of time spent on the computer. Individuals with previously undiagnosed vision problems may experience symptoms.
Several things can be done to reduce symptoms of CVS. One of the simplest things that you can do is to adjust your posture. Make sure that you position the monitor below eye level and at least 20 to 28 inches away from your face. This will help avoid straining your neck and eyes.
Consider installing an anti-glare screen filter to reduce the amount of glare that you absorb. Take frequent breaks when using your digital device. Another increasingly popular option is the use of blue light lenses.
Computers, tablets, smartphones, and other devices emit blue light. It has been proven that light in particular wavelengths can damage the retina. This can result in vision impairment. Wearing special glasses can help limit exposure to blue light.
Blue light lenses help block harmful blue light. The lenses also have non-glare protection. The glasses reduce the potential for eye damage and can improve symptoms of CVS.
Blue light-blocking lenses can help reduce eyestrain and improve focus. This will result in the eyes feeling less tired, and it will improve productivity. Using the glasses will also help improve the quality of your sleep. Prolonged exposure to digital screens can harm sleep patterns.
The high energy frequency emitted by the blue light can increase alertness while also delaying the release of melatonin. Blue light lenses can reduce the impact of the light, allowing you to enjoy a good night’s sleep.
Fortunately, for most people, computer vision syndrome is usually temporary. Once the individual stops using the device, the symptoms stop. However, some experience symptoms even after they stop using the digital device. The headaches, blurry vision, and other issues can remain long after. If your symptoms persist, visit an eye doctor for proper diagnosis and treatment.
Most people experience symptoms of computer vision syndrome after using digital devices for two or more hours. If you experience any symptoms when working on your computer, you need to visit an eye specialist. Failing to treat the condition can result in more eye issues.
