Computer vision syndrome (CVS) is a growing concern among individuals who spend a significant amount of time on computers, smartphones, and other digital devices. With the rise of remote work and online learning, the average person is spending more time in front of screens than ever before. As a result, many people are experiencing eye strain, dry eyes, blurred vision, headaches, and neck and shoulder pain. These symptoms can be caused by a combination of factors, including glare, poor lighting, and the need to focus on a small screen for long periods of time.
In this blog, we will explore the causes, symptoms, diagnosis, and treatment of CVS. We will also discuss the latest research and advancements in technology that are aimed at addressing the issue of CVS. Whether you’re a professional who spends hours in front of a computer, a student who is taking classes online, or simply someone who likes to spend time on their phone or tablet, this blog is for you.
In the context of neuroscience, computer vision syndrome (CVS) is thought to be caused by the way the brain processes visual information from a computer screen. When we look at a computer screen, our eyes are focused at a fixed distance, and our eyes are required to make small, rapid movements called saccades to scan the screen. This can cause the eyes to fatigue, leading to symptoms of CVS.
The brain also has to process the visual information from the screen, which is often backlit and can cause glare. This can make it difficult for the brain to distinguish between different levels of contrast, leading to eye strain and headaches. Additionally, prolonged use of digital devices can cause a decrease in blink rate, which can lead to dry eyes and increase the risk of infection.
The way the brain process visual information is a complex process, it can be influenced by multiple factors such as visual acuity, the ability of the eye to focus, and the way the brain interprets the visual information. In CVS, the brain is overloaded with visual information, which can cause it to strain, resulting in symptoms like headaches, blurred vision, and neck and shoulder pain.
The symptoms of CVS can vary from person to person, but some of the most common symptoms include:
The causes of Computer vision syndrome (CVS) can be broadly categorized as visual and environmental. The visual causes include the way the eyes focus and move when looking at a screen and the way the brain processes visual information from the screen. Environmental causes include the distance and angle of the screen, the lighting in the room, and the glare on the screen.
It’s worth noting that CVS is a multi-factorial condition and a combination of these factors can contribute to the development of the condition.
Computer vision syndrome (CVS) is generally diagnosed based on a patient’s symptoms and their history of computer use. A comprehensive eye examination by an optometrist or ophthalmologist is usually the first step in diagnosing CVS.
During the examination, the doctor will look for signs of eye strain, dry eyes, and other symptoms associated with CVS. They may also check the patient’s visual acuity, check the patient’s eye movements, and measure the patient’s near point of convergence.
The doctor may also perform additional tests to diagnose CVS such as:
Treatment options for CVS vary depending on the underlying cause of the symptoms, but can include a combination of the following:
It’s important to note that treatment for CVS should be tailored to the individual patient and their specific symptoms. It may involve a combination of different treatment options, and may require a multidisciplinary approach, involving an optometrist or ophthalmologist, ergonomist, and occupational therapist. Regular follow-up visits with the doctor are also important to monitor the progress of treatment and make any necessary adjustments.
There have been several technological innovations in recent years aimed at treating computer vision syndrome (CVS) and reducing the symptoms associated with prolonged computer use. Some of the latest innovations include:
At Bynocs, we will assign eyecare professionals to thoroughly analyze the nature of your CVS and accordingly plan your treatment. We have the expertise, facility, and solutions to provide a complete treatment with a combination of eye health monitoring software, VR/AR and video-game-based vision therapy solutions, and specialized glasses.
As mentioned previously, our eyes tend to burn out and fatigue when focusing at a fixed distance for a longer period of time; which is the usual case with working on computer screens. This repeated eye-fatigue can cause improper coordination between both eyes, and eye-brain interaction related to it.
At Bynocs, we can provide personalized Dichoptic video-game vision therapies. These video-game-based therapies and VR glasses present different images to each eye, and the brain is forced to process the visual information from both eyes simultaneously. This can help to improve the brain’s ability to process visual information more efficiently, which can lead to a reduction in symptoms associated with CVS.
Dichoptic-therapy-based vision therapies have been shown to be effective in improving visual symptoms associated with CVS, including eye strain, blurred vision, and double vision.
We also have visual treatment software and dedicated eyecare professionals to track and monitor the specific causes of your CVS. And, accordingly plan a treatment that uniquely addresses your ocular, neural, and circumstantial shortcomings.
