Is Reading on Mobile Phones and Tablets Harmful to the Eyes? Blue Light Filters and ARC Glass for Protection

Reading on mobile phones and tablets is a common habit for many individuals today. However, this activity can contribute to eye strain and discomfort, commonly referred to as digital eye strain or computer vision syndrome. Symptoms such as dry eyes, blurred vision, headaches, and fatigue are not uncommon. In this article, we will explore the factors causing eye strain, the role of blue light and filters, and the recommendations for mitigating eye strain while using mobile devices.

Eye Strain Factors

Screen Time

Prolonged use of screens can lead to increased eye strain due to various factors, including glare, screen brightness, and the distance from the eyes. The 20-20-20 rule is a practical way to manage this. The rule suggests looking away from the screen every 20 minutes to focus on something at least 20 feet away for at least 20 seconds.

Blink Rate

Another factor is the tendency to blink less frequently when looking at screens, which can lead to dryness and discomfort. This decrease in blinking is due to a reduced ability to perceive visual changes quickly in screen environments, a phenomenon known as visual capture.

Blue Light and Filters

Blue Light

Screens emit blue light, which has been a concern for potential eye damage and disruption of sleep patterns. However, current research does not conclusively show that blue light from screens causes permanent damage to the eyes. Therefore, while reducing blue light exposure can help decrease discomfort during prolonged screen use, it may not fully eliminate eye strain.

Blue Light Filters

Using a blue light filter or apps designed to reduce blue light exposure can be helpful. These tools soften the visual environment and make it less harsh on the eyes, but they do not completely eliminate fatigue or strain. Additionally, some studies suggest that long-term use of blue light filters can have side effects such as headaches and dizziness.

ARC Glass

ARC glasses with anti-reflective coating can reduce glare from screens and improve visual comfort. However, they do not provide complete protection against eye strain. Moreover, spending too much time in front of screens is the primary cause of eye strain, irrespective of whether you use blue light filters or not.

Recommendations for Mitigating Eye Strain

Follow the 20-20-20 Rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds to reduce eye strain. Adjust Screen Settings: Use night mode or blue light filters and adjust brightness to match ambient lighting. Maintain Proper Distance: Hold devices at least 16-30 inches away from your eyes to minimize strain. Stay Hydrated and Blink: Remember to blink frequently to keep your eyes moist and improve overall comfort.

Conclusion

While reading on mobile devices can cause eye strain, using blue light filters and ARC glasses can help alleviate some discomfort. However, it is essential to adopt regular breaks and proper screen habits to protect your eyes' health. The key is to balance digital usage with eye wellness practices.

It is worth noting that the sun's UV radiation is much more potent and harmful to the eyes than blue light emitted by electronic devices. Therefore, using blue light filters and ARC glasses are not substitutes for other healthy habits in managing eye strain.
