How many hours a day do you look at a computer, tablet, or phone?
Many of us have jobs that require us to stare at computers all day long. And this can truly put a strain on your eyes.
Eye problems that are caused by computer usage are called computer vision syndrome (CVS). It is not any one specific problem, but a whole range of eye strain and pain. Research has shown that between 50 and 90% of people who work on a computer for an extended period have some symptoms.
You may or may not be surprised, but adults are not the only ones affected by CVS. Kids who start on cell phones or I-pads during the day or at school, also can have issues. Their eye problems are also impacted by lighting and their posture.
How Do Computers Affect Vision?
Computer Vision Syndrome occurs when your eyes follow the same path over and over. The eye strain will also get worse the longer you continue the movement. Think about how hard your eyes work. They move back and forth as you read, they focus and refocus from images on the screen, and they also have to bounce from paper to screen. Computer work also becomes harder as you age and the lenses in your eyes becomes less flexible. Somewhere around age 40, your ability to focus on near and far objects will start to go away. Your eye doctor will call this condition presbyopia.
What Are the Symptoms?
There’s no proof that computer use causes any long-term damage to the eyes. But regular use can lead to eye strain and discomfort.
You may notice:
- Blurred vision
- Double vision
- Dry, red eyes
- Eye irritation
- Neck or back pain
Your eyes, like any other part of your body, needs to rest. Make sure that you take time out, away from computers and cell phones, to rest your eyes.
