Computer Vision Syndrome
Computer Vision Syndrome (CVS) is a common problem that we are seeing more frequently at Pflugerville Vision.
CVS is a temporary condition that is the result of extended, uninterrupted computer usage. CVS may also be the result of extended TV, videogame, or tablet usage.
When you are working on a computer for an extended period of time, your eyes are constantly re adjusting as you open new documents and scroll through text. After an extended period of time, our eye muscles, just like any other muscle, becomes fatigued.
Electronic screens are worse for eye strain than printed materials as the back light and lack of contrast require your eyes to work harder to maintain a clear picture.
The symptoms of SVS can include:
- Blurred vision
- Dry eye
- Neck pain
CVS can be amplified by a number of factors other than usage hours. Some additional factors that may affect CVS include:
- Distance from screen
- Existing refractive error
If you are experiencing any of the symptoms listed above or think you may be experiencing extended computer usage, there are a number of things you can do to eliminate or decrease your symptoms. Since CVS is typically a temporary condition, limiting your usage should lessen the affects you are experiencing. We also recommend that patients take regular breaks during use.
The 20-20-20 rule is an easy rule to keep in mind, which states that after every 20 minutes of computer use, you should focus on an item that is 20ft away, for 20 seconds. This will give your eyes a much needed break.
Positive ergonomics can also help with CVS, which means having good posture, arm position, maintaining proper screen distance, and etc.
At Pflugerville, we can also provide you with glasses specifically designed for eye strain and computer usage. This may include a bifocal lens, a prescription optimized for computer use, or a minor tinting to improve contrast.
