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.

Customized Prism Lenses for Eye Alignment

For some patients, digital eye strain isn't caused by the screen itself—it's caused by the extra effort required to keep both eyes working together. Even a small amount of eye misalignment can lead to headaches, eye fatigue, blurred vision, double vision, and difficulty focusing during prolonged computer use.

During your comprehensive eye examination, we'll evaluate how your eyes work together and determine whether a customized prism prescription may help improve your comfort.

Prism lenses may help relieve:

✔ Eye strain and visual fatigue
✔ Headaches during or after computer use
✔ Intermittent double vision
✔ Difficulty maintaining focus while reading or working
✔ Neck and shoulder tension associated with prolonged near work

Unlike one-size-fits-all solutions, prism is customized specifically to your eyes and visual needs. If indicated, we can incorporate prism directly into your eyeglass prescription to help your eyes work together more comfortably throughout the day.

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.
