Computer Vision Syndrome — also called digital eye strain — affects millions of people who spend hours on screens every day. Symptoms are real, but solutions exist. We identify the contributing factors and build a personalized plan to keep you comfortable.
Computer Vision Syndrome (CVS) refers to a range of eye and vision problems that result from prolonged screen use. Symptoms include eye strain, headaches, blurred vision, dry eyes, neck and shoulder pain, and difficulty refocusing between near and far. The condition is driven by a combination of factors: uncorrected refractive errors, reduced blink rate, poor viewing angles, screen glare, and accommodative stress from sustained near focus. The 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) can help but is rarely sufficient on its own. A proper evaluation identifies your specific contributing factors so we can address the root cause, not just the symptoms.
Computer Vision Syndrome doesn't discriminate — it affects office workers, students, and contact lens wearers alike. If your work or school day revolves around a screen, this page is for you.
Office workers and remote employees
Eight or more hours in front of a monitor strains the focusing system and dramatically reduces blink rate. Even with a "perfect" prescription, the intermediate distance of a computer screen is often poorly addressed by standard eyewear — computer glasses can make a significant difference.
Students with heavy device use
Schoolwork increasingly demands hours of screen time. Children and young adults are particularly susceptible to accommodative fatigue and often do not recognize that their symptoms are vision-related — they just feel tired, distracted, or prone to headaches.
Contact lens wearers on screens all day
Contact lens wear already reduces blink rate and tears — combine that with screen use and you have a recipe for significant discomfort. We can adjust your lens type, wear schedule, and supplement with computer-specific glasses to significantly reduce strain.
There is no single fix for Computer Vision Syndrome — effective management addresses your prescription, your screen setup, and any dry eye contributing to symptoms.
We assess your refractive error, focusing ability, eye teaming, and how your eyes perform at screen distances — often different from the distances tested on a standard eye chart. Even a small uncorrected prescription can cause significant CVS symptoms.
We offer computer glasses with occupational progressive or single-vision designs optimized for screen distance, anti-reflective coatings to reduce glare, and blue light filtering options. We'll recommend the right combination for your specific setup and visual needs.
Screen use reduces blink rate by up to 60%, which directly causes dry eye symptoms that worsen CVS. We evaluate tear film quality and address dry eye as part of CVS treatment. We also provide guidance on screen positioning, lighting, and break habits to reduce strain throughout your day.

Computer Vision Syndrome (CVS), also called digital eye strain, is a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and phone use. The American Optometric Association estimates that 50–90% of people who work at a computer screen have at least some symptoms. The condition is not permanent and responds well to treatment once contributing factors are identified.
The evidence on blue light specifically causing eye strain is mixed — most CVS symptoms are driven by screen glare, reduced blink rate, accommodative stress, and uncorrected prescriptions rather than blue light wavelengths alone. However, blue light filtering lenses paired with a quality anti-reflective coating can improve comfort for many patients, particularly in the evening. We'll give you an honest assessment of what is and isn't likely to help in your specific case.
Eye discomfort after screen use typically results from one or more of: sustained focusing at a fixed near distance (accommodative fatigue), reduced blinking leading to dry, irritated eyes, screen glare and poor lighting contrast, or an uncorrected or undercorrected prescription. In some cases, binocular vision issues — such as convergence insufficiency — make sustained screen use particularly difficult. A thorough evaluation identifies which of these is driving your symptoms.
No. Computer Vision Syndrome is not a permanent or progressive condition. Symptoms typically resolve or significantly improve with the right combination of prescription correction, lens choices, and ergonomic habits. There is no evidence that CVS causes lasting eye damage. However, if left unaddressed, it can significantly reduce productivity and quality of life for people who work on screens daily.
CVS and dry eye frequently overlap and share many symptoms — both can cause burning, redness, fatigue, and blurred vision. The key difference is that CVS is specifically triggered by screen use and involves the visual-focusing system, while dry eye is a chronic condition of the tear film that exists independently of screen use. Screen use worsens both. Treatment for CVS may include dry eye management as one component, but also addresses the optical and ergonomic factors that dry eye treatment alone does not resolve. If you are unsure whether your symptoms point to CVS or dry eye, our dry eye symptoms guide can help you identify the pattern.
A comprehensive evaluation for CVS can get you back to working comfortably — all day, every day.
