Smartphones and Eyes Health

What is any related smartphones and eyes health?

Smartphones is popular gadget since social media -twitter, facebook- addicted to people in around the world. This gadget make internet activity more private and joyful. But most people not yet aware that using smartphone in a long time is not good for eyes health.

According to the study, which appears in the July issue of Optometry and Vision Science, people reading text messages or browsing the Internet on their smartphones tend to hold the devices closer than they would a book or newspaper, forcing their eyes to work harder than usual. This closer distance — plus the often tiny font sizes on smartphones — could put added strain on people who already wear glasses or contact lenses.

“The fact that people are holding the devices at close distances means that the eyes have to work that much harder to focus on the print and to have their eyes pointed in right direction,” said study co-author Dr. Mark Rosenfield, a professor at the SUNY State College of Optometry in New York City. “The fact that the eyes are having to work harder means that people may get symptoms such as headaches and eye strain.”

Texting and browsing the Web on smartphones can also result in dry eye, discomfort and blurred vision after prolonged use, the study authors point out. Previous studies have also found that up to 90 percent of people who use computers experience eye problems.
