Read short messages or surfing the Internet through a smartphone tend to force people’s eyes to work harder than when reading books or newspapers. A study involving 130 volunteers, with an average age of 23.3 years old, studied how people hold the phone while reading a short message. Then, another 100 volunteers, with an average age of 24.9 years old were studied while they read the pages.
When we read newspapers, books, or printed magazines, the average distance to the eye is 40.64 centimeters. Apparently in average, people who read or send short messages is only 35.56 centimeters. eResearch by Navid Ajamin -- spring 2010
In some people, it is even closer about 17.78 centimeters. The research was done by a team from ‘SUNY State College of Optometry’ in New York City, the study states that the additional burden would cause complaints such as headaches, dry eyes, discomfort, myopic, and tension in the eyes. The results are published in the Optometry and Vision Science journal in July 2011.[1]
Computers and digital devices have certainly transformed the way the average worker completes their daily tasks, but they also pose a hidden danger to our eyes, one that many digital device users are simply unaware of. With so much time being spent in front of computerized screens--be it in front of the laptop or the iPhone--device users are increasingly suffering at the hands of what eye care professionals call Computer Vision Syndrome.
New research out from the firm VSP Vision Care shows that a big chunk of eye care patients today complain of the common symptoms attached to the syndrome. "Computer Vision Syndrome is a major problem for Americans," said Dr. Nate Bonilla-Warford, an eye doctor and a VSP provider. “We are seeing patients uncomfortable in the workplace with neck pain, headaches, eye strain, blurred vision, etc. that could easily be avoided.
It's important for people to discuss their digital usage with their eye doctor and make sure they are getting annual eye exams." Channel Insider takes a look at the study's findings and three important ways that doctors such as Bonilla-Warford recommend to prevent your screens from killing your vision.[2]
What happens if you spend hours on your phone?
Negative Effects of Too Much Screen Time:
Eye Strain and Headaches - Too much time spent looking at screens can cause fatigue or discomfort in your eyes as well as dimmed vision. Glare on screens and the brightness of the display can place further strain on your eyes. Eventually, this strain can lead to headaches.[3]
