How many hours a day do you spend looking at a screened piece of technology?

If you are like most of us, your answer could be anywhere between two and ten hours a day. You may or may not be surprised by this number if you work on a computer, own a smartphone or perhaps have a mild addiction to your Xbox, Netflix or Kindle. But have you ever felt a pounding, throbbing or aching feeling in your head after using your device? You may have Computer Vision Syndrome, or more commonly CVS. Computer Vision Syndrome is a term optometrists have given this form of eyestrain for people who look at device screens frequently.

People who look at screened devices all day require their eyes to focus on screen text, which is not as sharp as text found on a piece of paper. We also use our eyes ciliary muscles for extended periods of time to help us focus at short distances. Both of these can lead to eye discomfort and vision strain.

Solutions

One way the Ontario Association of Optometrists (OAO) suggests we combat the symptoms (which fade away after use of the device), is to follow the 20-20-20 rule. The 20-20-20 rule means we should stop staring at our devices every 20 minutes and focus on something else 20 feet away for at least 20 seconds to help give our eye muscles a break and rehydrate our eyes.

  1. The use of Smart Phones, relatively speaking, is a somewhat new trend (over the past 10 years). In such a small time frame can researchers and scientists truly come to a consensus on what a lifetime of CVS actually looks like? Since people have only had access to ready-to-use computer screens in their pockets for the past decade, what would 20-30 more years of CVS be like? Decades from now could there be a widespread epidemic of people suffering from CVS needing specialized eye treatment and care? Is the medical infrastructure in place to accommodate for such problems?
