DALLAS—
Dustin Lancaster is like a lot of people these days--never far from his personal laptop or his work computer where the interactive designer endlessly stares at tiny pixels and bright colors."I look at my computer probably more than eight hours a day and I'm constantly checking my mobile phone all day long," Dustin said.
And then when the 31year old gets home he watches movies on his laptop.
Dustin said two years ago it all became a digital blur.
"I noticed it immediately leaving the office after a full workday that I couldn't read road signs--they were really blurry and I just kind of chalked it up to being tired eyes just from staring at the monitor all day."
Dustin went to the eye doctor and out of the blue was diagnosed with astigmatism and nearsightedness.
He now wears glasses.
Baylor-Carrollton ophthalmologist Marvin Hsiao says that overuse of the eyes doesn't cause vision problems it can exasperate them.
According to The National Institute of Occupational Safety and Health--90% of people who spend more than three-hours a day at a computer complain of computer vision syndrome--commonly referred to as CVS.
Dr. Hsiao said many people suffer from vision fatigue.
"If you are on one of these devices a lot we don't blink as much when we are using a cell phone you know, we're staring at a cell phone or a computer all the time so our eyes become a big problem and can cause eye strain," Dr. Hsiao said.
And few doctors test for mid-range vision--that 40- inch span between your computer screen and your eyes--many people have turned to mid-range computer glasses to get through the work day.
Dustin remembers feeling achy and tired before he got his glasses.
Now the computer and smartphone screens are a vision.
According to the American Optometric Association more than 40% of Americans spend more than three hours a day in front of a computer or smartphone screen.
