Protecting Your Eyes During Extended Screen Time: The Myth of Blue Light Glasses and Real Recommendations

Spending extended periods of time in front of phone and computer screens has become an inseparable part of modern life, which significantly impacts eye health. In Georgia, both adolescents and adults spend considerable time in front of screens, often leading to eye fatigue and discomfort. In response to this issue, consumers frequently turn to blue light-blocking glasses, but it is essential to understand how effective this solution is.

Blue light is high-energy visible light that is located at the cool end of the color spectrum. It comes from both the sun and the screens of digital devices. In recent years, concern has grown that blue light may harm eye health, which has led to the popularity of blue light-blocking glasses. However, there is limited scientific evidence to support the reality of these fears.

The American Academy of Ophthalmology explains that there is insufficient evidence to support the effectiveness of blue light-blocking glasses. Research shows that the main cause of eye fatigue is not blue light but rather prolonged screen time, which leads to eye strain and dryness.

The primary cause of eye fatigue is continuous and prolonged contact with screens without giving the eyes proper rest. Constantly staring at a screen reduces the frequency of blinking, leading to dryness and strain. At the same time, inadequate lighting and excessive screen brightness can exacerbate eye discomfort.

Experts recommend following the “20-20-20” rule to protect eye health: every 20 minutes, look at something 20 feet away for 20 seconds. This practice helps relax the eyes and reduce strain. Additionally, adjusting screen brightness to match the ambient light in the room is important to prevent excessive stress on the eyes.

Some devices, such as the iPhone, offer features like “Night Shift,” which reduces blue light emission during nighttime hours. While these modes reduce blue light exposure, they do not eliminate the need for regular eye rest, which remains the key strategy for maintaining eye health.

Scientists and ophthalmologists argue that blue light-blocking glasses are not an essential investment for protecting eye health. Periodic eye rest and proper screen time management are more effective. People should focus on regularly blinking their eyes, adjusting screen brightness appropriately, and positioning their monitors correctly to avoid unnecessary strain.

Regular eye exams with a specialist are also essential to detect and address any eye health issues early on. If symptoms such as eye dryness, fatigue, or pain appear, it is recommended to consult with an ophthalmologist and receive appropriate guidance.

In general, the use of blue light-blocking glasses is often not a necessary investment for eye health protection. The main priority should be regular eye rest, proper adjustment of screen brightness and position, and optimization of screen time. This is important for people of all ages, especially those who spend significant time with digital devices. By following these best practices for eye protection, it is possible to maintain eye health and avoid unnecessary strain.
