Tips on How to Reduce Eye Strain for Web Developers

Hello, fellow developers! I’m Mike, a web developer with 15 years of experience under my belt. Like many of you, I found myself transitioning to a remote work setup in 2020. While this move came with its fair share of perks (read: no commute and wearing pajamas to work), it also meant spending more hours than ever before glued to my screen in the quest for perfect code.

In my well-equipped office environment, I used to take my eyes for granted. But once I started working from home, I began to notice the toll my marathon coding sessions were taking on my eye health. My eyes would often end the day red, dry, and feeling swollen. Moreover, I found myself frequently rubbing my eyes throughout the day, a habit I knew was far from ideal.

That’s when I decided to take control of the situation and began researching ways to combat digital eye strain. I discovered that there’s a lot more to it than just blinking more often or taking a break to stare out of the window now and then. While these methods do help, there’s a whole host of other strategies that can make a significant difference in maintaining your eye health.

This guide is an amalgamation of my personal experiences and findings on how to combat eye strain effectively. As a web developer, your eyes are one of your most valuable assets. Therefore, it’s crucial to protect them from the negative impacts of excessive screen time. Join me as I delve into the world of eye care, discussing everything from workspace setup to helpful tools, and even eye exercises. My aim is to help you maintain your eye health and ensure sustainable productivity in your home office. Welcome to the definitive guide on combating eye strain for developers!


Understanding Eye Strain: Symptoms and Causes

Before we delve into solutions, let’s understand the problem at hand. Eye strain, also known as asthenopia, is a common condition that happens when your eyes get tired from intense use, such as staring at digital screens for extended periods. While this isn’t typically serious and often goes away once you rest your eyes, the discomfort can be quite bothersome.

As a web developer, you’re likely no stranger to the symptoms of digital eye strain. Personally, I’ve experienced a range of symptoms. My eyes often end the day feeling dry and red. There’s also a sensation of them being swollen, and I find myself rubbing my eyes more frequently than I’d like to admit.

The symptoms of eye strain can vary between individuals, but common ones include:

  • Eye discomfort
  • Headaches
  • Sore, tired, burning, or itching eyes
  • Difficulty focusing
  • Watery or dry eyes
  • Blurred or double vision
  • Increased sensitivity to light

The primary cause of these symptoms in our line of work is prolonged computer use. Focusing on code for hours on end causes our eyes to work harder, leading to strain. Additionally, poor lighting, improper viewing distances, glare on the digital screen, and poor seating posture can all contribute to eye strain.

Furthermore, the unique challenge with coding or any other task that requires intense focus is that we tend to blink less. Blinking is essential as it helps to moisten the eyes, preventing dryness and irritation.

In a traditional office setup, employers often invest in ergonomic furniture and proper lighting to reduce the risk of eye strain and other work-related injuries. However, in a home office, these factors are often overlooked. But, with some careful attention to your workspace setup, you can significantly alleviate eye strain. For more details on how to set up an ergonomic home office, you can refer to our comprehensive guide on ergonomic home office setups.

In the next sections, we’ll look at how to mitigate these factors and reduce the risk of eye strain. Stay with me as we explore practical, actionable strategies to protect your eyes.


5 Essential Tips to Prevent Eye Fatigue

Eye fatigue is not a price you should have to pay for long hours of coding. There are several simple and effective strategies you can adopt to prevent it. Let’s explore five of these.

1. Monitor Position and Setup

The way your monitor is positioned can significantly influence eye strain. The distance, angle, and height all come into play. But what does ‘eye level’ truly mean?

Well, when we say your monitor should be at eye level, we mean the top of your screen should be at or slightly below your eye level when you’re sitting up straight. This position allows you to look slightly down at your work, which is easier on the eyes than looking straight ahead or looking up.

The rule of thumb is that your screen should be about an arm’s length away. At this distance, you should be able to comfortably read text on the screen without leaning in or squinting.

For those of you with dual or triple monitor setups, the game changes slightly. The primary monitor you use should still be directly in front of you at eye level. The secondary monitor should then be immediately next to the primary monitor. To prevent unnecessary head and eye movement, the screens should be angled such that they form a slight arc. This setup allows you to merely shift your gaze, not your entire head, when you need to look at the other monitor.

One common problem I’ve encountered is that the desk height doesn’t always align with the ideal monitor height, causing me to slouch or strain my neck. A monitor riser can be a game-changer here, raising your screen to the perfect height and simultaneously providing additional storage space underneath. If you’re interested in this solution, check out our article on monitor risers.

Remember, the goal is to make your environment adapt to you, not the other way around. A proper monitor setup is the first step in ensuring your eyes aren’t working overtime.

In the next section, we’ll look at some more ways to give your eyes a well-deserved break.

2. The 20-20-20 Rule

Have you heard of the 20-20-20 rule? This simple practice can do wonders to alleviate eye strain and it’s remarkably easy to incorporate into your workday.

Here’s how it works: every 20 minutes, take a 20-second break and look at something 20 feet away. Why does this help? Staring at a screen for prolonged periods causes your eyes to work hard and focusing on distant objects gives your eyes a chance to relax.

But why 20 feet? This distance is considered ‘optical infinity’ in the ophthalmology world. At this distance, your eyes are essentially at rest as they don’t need to work to adjust focus.

Now, I know what you’re thinking: “How on earth am I going to remember to do this every 20 minutes?” Here are a few suggestions:

  1. Set a Timer: Use your phone or a desktop app to set recurring 20-minute reminders. When the alarm goes off, it’s time for a 20-second break.
  2. Use Productivity Apps: Several apps are designed to remind you to take breaks and rest your eyes, such as Eye Care 20 20 20 and ProtectYourVision.
  3. Align it with Other Activities: If you drink as much coffee or water as I do, nature’s call might serve as a natural timer. Each time you get up, take a moment to look out a window or at a distant object.

The 20-20-20 rule is a small habit that can have a big impact on reducing eye strain. Remember, your eyes need regular breaks just as much as the rest of your body. In the next section, we’ll discuss how you can optimize your screen settings for better eye comfort.

3. Proper Lighting and Workspace Setup

Your workspace’s lighting plays a crucial role in either alleviating or exacerbating eye strain. Improper lighting can cause you to squint or strain to see your screen, leading to tired, sore eyes. So, how can you optimize your workspace lighting to prevent eye fatigue?

  1. Avoid Direct Light: Position your desk so that windows are to the side, rather than in front or behind you. This prevents direct sunlight from shining on your screen and causing glare, which can strain your eyes. If you can’t avoid direct light, consider using blinds or curtains to diffuse the light.
  2. Use Task Lighting: Rather than relying on overhead lights, use task lighting. A desk lamp with a cool white bulb can provide the right amount of light without causing a harsh glare.
  3. Mind the Background: A dark screen against a brightly lit background or vice versa can cause eye strain. Try to keep your screen brightness in balance with your surroundings.
  4. Consider a Bias Light: This is a light source placed behind your monitor, providing a subtle glow that reduces the stark contrast between a bright screen and a dark room.
  5. Opt for Matte Surfaces: If possible, choose matte over glossy for your desk and other large surfaces in your office. Matte surfaces reduce glare and are easier on your eyes.

Remember, what works for one person may not work for another, so feel free to experiment and see what setup reduces eye strain for you the most. In the next section, we’ll dive into the digital changes you can make to your computer to aid in reducing eye strain.

4. Tools and Software Aids

Even with a properly set up workspace, staring at a computer screen for prolonged periods can be hard on your eyes. Luckily, several digital tools can help mitigate some of the strain. Here are some you might find helpful:

Blue Light Filters: Many devices now offer built-in blue light filters (often called “night mode” or something similar) that change the color temperature of your screen to reduce the amount of blue light it emits. Blue light has been linked to digital eye strain and sleep disturbances. However, as I’ve found in my own work, these filters can distort colors, making them less than ideal when you need color accuracy for design tasks. The solution? Consider using blue light filters during tasks that don’t require accurate color representation and switch them off when color matters.

Brightness and Contrast Adjustments: Adjusting the brightness and contrast of your monitor to match your workspace lighting can also reduce eye strain. The goal is to balance your screen with the surrounding environment so that it’s not much brighter or darker. Many monitors have an “auto-brightness” feature that adjusts the screen’s brightness based on the ambient light.

Text Size and Display Settings: Increasing the text size and zoom can reduce the need for your eyes to strain to read small text. Similarly, keeping your screen resolution at its native setting ensures that text and images are sharp and easy to see. If you’re using VS Code, you can adjust the zoom level with the View > Appearance > Zoom In/Zoom Out menu options, or use the keyboard shortcuts Ctrl + = to zoom in and Ctrl + - to zoom out. To reset the zoom level to default, use Ctrl + 0. Remember, you can always adjust your settings to suit your comfort.

Break Reminder Tools: Several software tools can remind you to take regular breaks, helping enforce practices like the 20-20-20 rule. Examples include EyeLeo, ProtectYourVision, and Time Out.

Flux: This software adjusts your computer display’s color temperature according to time of day and light. It’s warmer at night and like sunlight during the day, helping reduce strain on your eyes.

Remember, no single tool will be a magic cure for eye strain. It’s all about using these aids in conjunction with good habits and a properly set up workspace. In our next section, we’ll explore some eye exercises recommended by eye care professionals.

5. Eye Exercises and Breaks

Beyond workspace setup and digital tools, one of the most effective ways to combat eye strain is surprisingly simple: taking regular breaks. However, not all breaks are created equal when it comes to eye health. Let’s look at some ways to maximize your rest periods for optimal eye comfort.

Importance of Rest: Just as the muscles in your body need rest after a workout, your eyes need a break from the constant focus on near tasks, like reading a computer screen. Regular short breaks can help alleviate the symptoms of eye strain and prevent further eye fatigue.

Eye Exercises: Eye exercises, often referred to as vision training or eye yoga, involve performing a series of eye movements designed to strengthen the eye muscles and improve vision. While research is still ongoing, some studies suggest these exercises may help slow the progression of conditions like myopia and age-related macular degeneration. Here are a few simple exercises you can try:

  • Focus Change: Hold your finger a few inches away from your eye. Focus on your finger for a few seconds, then shift your focus to an object farther away for a few seconds. Repeat this several times.
  • Figure Eight: Imagine a giant figure eight about 10 feet in front of you. Trace the figure eight with your eyes, moving slowly without moving your head. Do this a few times, then switch directions.
  • Blinking: Blinking is an often-overlooked but effective eye exercise. Rapid blinking for a few seconds can help refresh your eyes and reduce eye strain.

The 20-20-20 Rule: As mentioned earlier, the 20-20-20 rule is a simple yet effective practice to reduce eye strain. Every 20 minutes, look away from your computer screen and focus on an object at least 20 feet away for 20 seconds. This gives your eye muscles a break from the strain of close-up work.

Remember, these exercises are not a replacement for professional eye care. If you’re experiencing persistent eye strain or other vision issues, it’s always a good idea to consult with an eye care professional. In the next section, we’ll wrap up with some final thoughts and additional resources.

Seeking Professional Help

While the tips provided above can significantly help alleviate and prevent eye strain, it’s important to recognize when it’s time to seek professional help. Persistent eye discomfort, vision changes, or symptoms that interfere with your work are all signs that you should consult an eye care professional.

Professionals like optometrists and ophthalmologists are equipped with the knowledge and tools to diagnose and treat a wide range of eye conditions, including those related to prolonged screen use. Here are some scenarios where you might consider booking an appointment:

  • Persistent symptoms: If your eye discomfort continues despite following the recommended tips, it’s a good idea to get an expert opinion. You might be dealing with more than just eye strain.
  • Vision changes: If you notice any changes in your vision, such as blurriness, double vision, or difficulty focusing, it’s important to get checked out. These could be signs of more serious eye conditions.
  • Physical changes: Any visible changes to your eyes, such as redness, swelling, or involuntary movement, should be examined by a professional.

When consulting an eye care professional, here are some questions you might consider asking:

  1. What could be the cause of my symptoms?
  2. Are there any tests you recommend?
  3. Could my current glasses or contacts prescription be contributing to the problem?
  4. Are there any specific eye exercises you recommend for my situation?
  5. What changes can I make in my workspace to reduce eye strain?
