Computer Vision Syndrome


Hi, it’s Ranjeet Bajwa from Buena Vista Optometry. I wanted to talk to you today briefly about computer vision syndrome as computers have become more ubiquitous in our environments of the home at work at school as well as for fun it has definitely taken a toll on our eyes and one of the things that becomes very common for our patients is computer vision syndrome. Computer vision syndrome is a combined group of different types of issues that can arise from computer vision use that all fall under the umbrella of computer vision syndrome.

Of the many things that are out there to help combat computer vision syndrome one of the things that we strongly recommend is the 20-20-20 rule it’s a very simple rule easy to remember because it has that ring, ‘20-20-20’ but what you want to do is a 20-minutes computer or electronics use after that 20 minute time frame take 20 seconds look at something 20 feet away or further.

Basically what that’s going to allow you to do does it relax the muscle of your eyes to help reduce some of that eye strain you might encounter in the activities that come with an electronics use. To help reduce the digital eye strain that we talked about and the other symptoms that can come along with it include headaches, dry eyes, blurred visions and more. So, when we talk about taking it easy on your eyes or to remain conscientious of your visual hygiene that’s usually what we’re talking about, and the 20-20-20 rule is a great way of doing that.

A couple other options that are out there for those of you who are Apple users on the iOS system of some of the newer versions there is the night shift that you can put on there’s different ways of setting that up you can set it up off your home screen or you can actually go into settings and have it set based on the actual rising and setting of the sun. The nice thing about this, it shifts the blue light exposure to minimize that to help reduce the melatonin levels in the body so that you can have a little bit more of a normal sleep pattern because a lot of us are on our electronics before we go to bed and that’s been shown to be disruptive to your normal sleep cycle.

And lastly something new that I just recently learned about which I’m pretty enthusiastic to time and loop into my daily routine is for those people that use the Google Chrome browser, there is a new extension called the break timer and the break timer extension will remind you to take a break every 20 minutes to stay on track with that 20 20 20 roll that we talked about.

Again, this is Dr. Ranjeet Bajwa from Buena Vista optometry in Ventura, California. If you ever have any questions or concerns about your eyes by all means feel free to reach out to me at @DrRajBaj on Twitter and you can always reach us on our website at

Computer Vision Syndrome describes a group of eye and vision-related problems that result from prolonged computer use. Many individuals experience eye discomfort and vision problems when viewing a computer screen for extended periods. The level of discomfort appears to increase with the amount of computer use.

Since 43% of adults work at jobs that require prolonged use of a computer, tablet or other digital devices, computer vision syndrome (CVS) and blue light exposure are becoming increasingly serious threats to our vision, health and productivity.

Computer Vision Syndrome (CVS) in the Ventura, CA workplace, also known as digital eye strain, is an increasingly common condition felt by those that spend two or more hours daily in front of a screen. Symptoms can include blurred vision, eye strain and fatigue, headaches, dry, red, irritated eyes, neck and back pain and headaches. Typically the symptoms of CVS are not permanent, however they can have an impact on comfort, productivity and one’s ability to focus. In rare cases, CVS can even be debilitating.

Studies show that symptoms of computer vision syndrome have become the most common workplace complaint or injury among workers with 50-90% of computer users reporting symptoms to some degree. These symptoms have been shown to have an impact on worker productivity.

The Effects of CVS on Productivity

In a study which looked at the correlation between computer vision and workplace productivity performed at the School of Optometry at the University of Alabama at Birmingham correlations were found between proper vision correction and overall productivity as well as the time it takes for a worker to complete a task. Even minor and unnoticeable vision problems were shown to affect productivity by up to 20% and to cause an increase in mistakes.

Blue Light Exposure Blue light or high-energy visible (HEV) radiation exposure is another effect of extended digital device use. Excessive blue light exposure in Ventura has been linked to sleep cycle disturbance – which can have an overall negative impact on alertness and one’s ability to focus. Blue light may also cause long term damage to the retina. While studies are currently being done to determine the effects of blue light, it is clear that protecting your eyes from blue light is recommended for eye health.

Workspace Ergonomics and Computer Eyewear

From both the worker’s and the employer’s perspectives, an investment in a combination of workspace ergonomics and computer eyewear can benefit the workplace and overall productivity. Workers will be more productive and experience fewer visual and musculoskeletal symptoms that can cause discomfort and distraction. Employers will benefit from productivity gains and reduced worker’s compensation claims.
