Computer Vision Syndrome

Digital screens are part of life—eye strain doesn’t have to be.

What Is Computer Vision Syndrome?
Also known as digital eye strain, Computer Vision Syndrome (CVS) refers to a group of eye and vision-related problems caused by prolonged screen use. With the rise of computers, smartphones, and tablets in both work and school, CVS has become one of the most common modern-day vision complaints.

Studies estimate that 50–90% of people who use screens regularly experience symptoms of digital eye strain at some point.

What Causes CVS?
CVS is similar to other repetitive strain conditions—like carpal tunnel syndrome. It happens because screen use demands constant eye movement, focusing, and refocusing, often for hours without a break.

Unlike reading a book, screens add extra stressors to your visual system:

• Glare and screen reflections

• Poor contrast

• Unstable refresh rates

• Blue light emission

• Small text and bright backlighting
  

If you already need vision correction—and don’t wear the right prescription—these issues can be magnified. Age-related changes like presbyopia (common after age 40) can also make screen work more uncomfortable.

Common Symptoms of CVS
If you’ve been working at a computer or staring at your phone all day, you might notice:

• Blurry or fluctuating vision

• Headaches

• Dry, red, or irritated eyes

• Eye fatigue or discomfort

• Neck, shoulder, or back pain

• Difficulty focusing

• Double vision
  

While CVS doesn’t cause permanent eye damage, it can impact productivity, comfort, and quality of life if left unmanaged.

How We Treat Digital Eye Strain
CVS is highly manageable—especially with personalized treatment. At Slabtown Eye Care, we go beyond generic advice to deliver tailored solutions based on how you use your digital devices.

Neurolens®: Relief for Eye Misalignment
Some patients experience CVS symptoms due to subtle misalignment between their eyes, especially at near and intermediate distances. This can cause ongoing tension, visual fatigue, and even neck or shoulder pain.

Neurolens® uses contoured prism technology to gently realign how your eyes work together. These lenses can provide fast, noticeable relief from:

• Headaches

• Eye strain

• Neck and shoulder tension

• Trouble focusing at the computer
  

We offer in-office testing to measure your alignment and determine if Neurolens is right for you.

Custom Computer Prescription
General glasses don’t always match the way you work. We create custom computer prescriptions based on your posture, desk setup, and screen distance. These lenses:

• Are optimized for intermediate and near zones

• Include anti-glare coatings and blue light filtering

• Help reduce strain and support all-day focus
  

Tailored to your specific setup, these prescriptions are ideal for modern professionals and remote workers alike.

Ergonomic & Environmental Adjustments

• Position your screen 20–28 inches from your eyes and slightly below eye level

• Reduce glare with blinds, proper lighting, or screen filters

• Use a document holder to minimize constant visual refocusing

The 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds to give your eyes a quick reset.

Updated Prescriptions & Dry Eye Support
We ensure your eyewear is up to date and may recommend dry eye treatments if needed.
