Between laptops, phones, and tablets, most of us spend more time in front of screens than ever before. Whether it’s a full day of work, online classes, or catching up on your favorite shows, hours of screen time can leave your eyes feeling tired and strained. This discomfort has a name: Computer Vision Syndrome, also known as Digital Eye Strain.

It’s one of the most common modern-day eye problems, affecting millions of people worldwide. The good news is that with a few simple adjustments and the right eyewear, you can keep your eyes comfortable and healthy, even in our digital-first world.

What Is Computer Vision Syndrome?

Computer Vision Syndrome (CVS) is a collection of eye and vision problems caused by prolonged use of digital devices. It happens when your eyes have to constantly focus and refocus as they move between screens, text, and images at varying distances. The result is eye fatigue, discomfort, and sometimes even blurred vision.

According to the American Optometric Association, as many as 70 percent of people who use computers for work experience symptoms of digital eye strain. The condition affects both adults and children, and it tends to worsen with longer screen sessions and poor visual ergonomics.

In simple terms, CVS is your eyes telling you they need a break.

Common Symptoms of Computer Vision Syndrome

The signs of computer vision syndrome can vary, but they often build gradually over time. You might notice your eyes feeling sore or heavy after long hours at the computer, or find yourself rubbing them more often. Some people experience headaches, blurry vision, or difficulty refocusing when looking away from their screens.

Dryness is another common symptom, since people blink less frequently when concentrating on digital content. This reduced blink rate can cause the eyes to become red, irritated, or watery. Neck, shoulder, and back pain can also accompany eye strain, especially if your workstation setup is not ergonomically designed.

If any of these symptoms sound familiar, your eyes are likely feeling the effects of too much screen time.

What Causes Computer Vision Syndrome?

The causes of CVS are multifaceted, combining both visual and environmental factors.

• Screen distance and focus strain: When you stare at a screen, your eyes must constantly adjust focus. Unlike reading a printed page, digital text lacks consistent contrast and definition, which forces your eyes to work harder.
• Reduced blink rate: Most people blink up to 60 percent less when using digital devices. This means the tear film that protects and lubricates your eyes evaporates more quickly, leading to dryness and discomfort.
• Blue light exposure: Screens emit blue light, a high-energy wavelength that can cause visual fatigue and may interfere with natural sleep cycles.
• Glare and lighting: Poor lighting, glare from screens, or reflections from overhead lights can strain your eyes further.
• Posture and ergonomics: Sitting too close to the screen or at an awkward angle can increase both visual and muscular strain.

Each of these factors adds up, especially over long workdays, making consistent protection and good habits essential.

How to Prevent Computer Vision Syndrome

• You don’t have to give up your digital life to protect your eyes. A few small changes to your daily habits can make a major difference in how your eyes feel.
• Start by following the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for at least 20 seconds. This simple practice relaxes the eye muscles and reduces fatigue.
• Adjust your screen position so that it sits slightly below eye level and about an arm’s length away. Avoid bright overhead lighting or direct sunlight on your screen, and consider using a matte filter if glare is an issue.
• Blink more often, especially during tasks that require focus, and keep artificial tears or eye drops nearby to maintain moisture. Short, regular breaks throughout the day can also prevent discomfort. Even standing up to stretch every hour helps reset your eyes and posture.

These small adjustments can greatly improve visual comfort over time.

The Role of Blue Light Glasses

One of the most effective ways to support your eyes in the digital age is by wearing blue light blocking glasses. These lenses are designed to filter out part of the high-energy visible blue light emitted by digital screens.

Blue light is not inherently harmful, but extended exposure can contribute to visual fatigue and make it harder to wind down at night. Blue light glasses help reduce glare, improve visual clarity, and may support healthier sleep patterns by minimizing exposure before bedtime.

EyeCandys offers a range of blue light glasses that combine functionality with style. Available with or without prescription lenses, they are a simple yet effective way to protect your eyes while working, studying, or scrolling.

When to See an Eye Doctor

If you experience ongoing eye discomfort, persistent headaches, or blurred vision that doesn’t improve with breaks, it’s important to schedule an eye exam. An optometrist can rule out underlying conditions such as uncorrected vision problems, dry eye, or astigmatism, which can worsen symptoms of computer vision syndrome.

Regular checkups also help ensure your prescription is current, which is especially important if you rely on digital devices daily.

Eye Health in a Digital World

Screens are part of modern life, but that doesn’t mean your eyes have to suffer. By making conscious changes to your work habits, optimizing your environment, and wearing protective eyewear, you can keep your eyes comfortable and healthy no matter how much time you spend online.

Your eyes are doing more work than ever before. Treat them with the same care you give to your skin, your posture, or your overall wellness.
