In today’s digitally dominated society, it’s normal for someone to spend a few hours looking at screens daily for work purposes, browsing social media sites, or other kinds of amusement. However, most people experience periods of obscured vision, eye strain, and discomfort after these prolonged periods of screen use. You are not alone, and if you are among those who have experienced these symptoms, read on. This phenomenon has come to be widely known as either digital eye strain or computer vision syndrome and directly impacts a considerable percentage of the population. Understand why this happens and how to alleviate it to make a big difference in your visual comfort and overall well-being.

Why Does Screen Time Affect Vision?

Digital Eye Strain : Digital eye strain can be defined as discomfort or vision-related problems that result from how humans stare at screens for hours. Some reasons your eyes work harder than usual when looking at a screen:

• Reduction in Blink Rate: Normally, you would blink 15-20 times within a minute when working with a screen, but the rate could drop significantly to sometimes under half. Blinking is necessary to keep your eyes moistened and clean. Reduced blinking, therefore, might lead to dryness of the eyes, irritation, and blurred vision.
• Close-Up Work: The screens place you in a position that has a demand for focusing on close objects to your eyes, which puts a mounting demand on the ciliary muscles around your eyes. Continuing to focus on objects is likely to lead to eye fatigue and even momentary blurred vision, as the muscular nature of the eye eyes gets tired.
• Exposure to Blue Light: High-energy blue light emanating from screens can cause eye strain. Though it won’t damage them permanently, it will disrupt your sleeping patterns and cause more discomfort when the screen is used continuously.

Computer Vision Syndrome

Computer Vision Syndrome is a group of symptoms that can be experienced while working continuously on the computer. It may either cause blurred vision or be followed by other complaints, such as:

• Headaches
• Dry Eyes
• Neck and Shoulder Pain
• Blurred Vision

These symptoms develop as a result of the continuous visual effort involved in working on screens, mostly aggravated by poor posture and inadequate setup of screens.

How to Rectify the Problem: Practical Tips and Techniques

Fortunately, there are many ways through which someone can reduce the risk of developing digital eye strain and blurry vision concerning the prolonged use of screens. These include:

1. Observe the 20-20-20 Rule:

Take regular breaks for your eyes: The 20-20-20 rule, where every 20 minutes you take your eyes off your screen, and look into the distance about 20 feet away, for at least 20 seconds should do the trick. This is an easy way for the extraocular muscles of the eye to relax, allowing your eyes to take a break from constant focusing. You can set up reminders on your device or use reminders downloaded from app stores that will inform you to take such short breaks.

2. Change Screen Settings: You can minimize the impact of eye strain from screen time if you modify the following settings on your screen:

• Brightness: Ensure your screen brightness aligns with the surrounding lighting. Avoid too bright or dim screen, as this can strain the eyes.
• Text Size and Contrast: Increase the text size to make reading more comfortable. Also, adjust the contrast between it and its background to reduce the reading effort that originates from high contrast.
• Blue Light Filters: Many screens have built-in blue light filters or “night mode” settings. Toggling their activation will help to cut down a degree of blue light exposure and might make some of the effects less painful.

3. Optimize Your Workspace Ergonomics

An ergonomically correct workspace is bound to help reduce the strain:

• Screen Position: The top of the screen should be at or below eye level and about an arm’s length away. This positioning eliminates the tilt of the head and avoids stress on the neck.
• Lighting: Make sure that the glare on the screen is minimized by placing a light source away from the screen and that there is no reflection from windows or overhead lights on the screen.
• Chair and Desk: Use a chair that supports good posture and a desk that allows you to keep your feet flat on the floor. When your elbows are bent at a 90-degree angle in typing, this keeps your hands in the correct position.

4. Blink More Often: Blink often while going through computers. It helps to regularly blink to keep your eyes moist and prevent dryness and irritation. Some people help themselves by using artificial tears or lubricating eye drops when it’s dry.

5. Consider Computer Glasses : Specialty screen use glasses can be used to minimize eye strain. Such special glasses are often combined with anti-reflective coatings and blue light filters. Consult an eye care professional if you need computer glasses.

6. Regular Eye Exams: Regular eye exams with the best eye specialist in India help to ensure that your eyes are healthy and meet daily visual demands effectively. Your eye care provider can evaluate the sharpness of your vision and determine any condition contributing to your symptoms. It can also provide you with specific ways to reduce digital eye strain, along with a proper modality for treatment or corrective lenses if necessary.

7. Follow the 20-20-20-20 Rule : A variation of this rule is to look at something 20 feet away every 20 minutes. The 20-20-20- rule helps give an extra eye break and moisture.

8. Exercise Your Eyes : For example, there are eye exercises, which would reduce any such strain and develop the level of focus. One of the simplest exercises is looking around and moving your eyes gradually from side to side and up and down, or focusing on some nearby object and then changing the focus to some distant object.

Conclusion

Blurred vision and eye strain due to too much screen time are common hazards in today’s digital world but are controllable with the right strategies.
