MIAMI (CBSMiami) – Nearly 60 percent of Americans use digital devices for five or more hours each day and most of us use two or more devices at a time.

How we use our eyes in this technology-driven world can have a serious effect on our vision.

Kay Bauer is an occupational therapist and relies on her contact lenses to keep her going throughout her day.

“I see patients at home. I do home health,” said Bauer. “So that’s why I’m constantly in and out of the car.”

By the end of her day Bauer says she feels the strain on her eyes.

“On the cell phone, for sure, texting a lot,” she said. “I’m on the computer a lot. I do a lot of eye straining.”

The vision council reports 90 percent of Americans use digital devices for two or more hours a day and 76% of Americans look at their digital devices in the hour before going to sleep.

Dr. Barry Kay says we all have a natural blink rate that replenishes the tears in our eyes — when we star at digital devices we don’t blink as often and that causes our eyes to dry out and strain.

“It’s become a very visual world,” said Dr. Kay. “More people working at closer distance can create eye strain and tired eyes.”

Dr. Kay says for those who wear contacts there is a solution.

“This new Acuevue is called oasis with hydrolux. And what they’ve done with this lens is they actually made it much smoother. Kind of like going to a 100-count thread sheet to maybe a 1000-count,” he said.

Acuevue is a one day contact lens – Bauer has been using it for two weeks and says has seen a major difference.

“I don’t even feel like I have contacts in,” Bauer said.

If you don’t wear contact dr. Kay says there is a way you can protect your eyes. He recommends an eye stretching exercise of sorts.

“One of the things I tell my patients because computers are so stressful,” explained Dr. Kay. “Is something we call the 20-20-20 rule. And the rule is this every 20 minutes look at least 20 feet away for 20 seconds.”
