It is not unusual for us to hear complaints about eyestrain, eye fatigue, blurred vision, dry or red eyes, and even headaches. There is often a strong correlation between these symptoms and the amount of time spent on computers, tablets or smart phones.
Our visual system isn’t designed to stare at screens for prolonged hours. With the change in technology our eyes are being used in new ways. This can cause symptoms that can potentially damage our eyes.
The condition is called Computer Vision Syndrome (digital eyestrain). It is the temporary discomfort that follows prolonged digital device use. These devices include televisions, computers, smart phones, e-readers, and tablets.
So what can we do to keep our eyes healthy while using digital devices? First, you need the proper prescription. If you don’t, this can cause headaches and eyestrain that could have been avoided. Many patients find comfort with computer glasses that provide wider focus for both the computer screen and reading distances.
Second, reduce glare from excessive lighting. Overhead lighting or sunlight may be causing reflections on your monitor. You can adjust the brightness, contrast or size of your font to reduce strain. Many patients report improved comfort on e-readers by adjusting text size.
Third, blink! Studies show that when we read or watch TV we blink less. This causes tear evaporation and dryness. Sometimes treatments or medications may be needed, such as LipiFlow, punctual plugs, Restasis, fish oils or artificial tears.
Finally, take breaks! When we stare at screens our eyes strain. The muscle in our eye that accommodates needs to relax. This can be done with the 20/20 rule. For every 20 minutes of near activity take a 20 second break and blink several times.
Studies also show that prolonged exposure to LED screens can damage retinal cells and increase risk for macular degeneration. Luckily, there are lenses that block this damaging light.
With the ease technology offers, we must take precautions to avoid the damaging effects to our eyes. To schedule an appointment with one of our doctors call 435-414-1449 or visit our website at SouthWestVision.org.
