Technology! How does it affect our eyes?

In our rapidly advancing technological era, computers have become a part of our daily lives. We spend a significant amount of time in front of screens. However, the use of digital devices has brought concerns regarding the health impact of prolonged screen time, in relation to the blue light emitted by these screens.

What does blue light do?

Blue light has shorter wavelength and higher energy and is present in both natural sunlight and the screens of our digital devices. Blue light has an impact on our circadian rhythms. Exposure to natural light during the day, helps regulate our sleep-wake cycle. However, prolonged exposure to artificial blue light at night, primarily emitted by screens, can suppress the production of melatonin, the hormone responsible for sleep. This can lead to difficulties falling asleep and poorer sleep quality.

Digital eye strain:

Another concern associated with extensive computer use is digital eye strain. Staring at screens for extended periods can cause symptoms like eye fatigue, headaches, and blurred vision.

What can we do to help protect out eyes?

1. Adjusting Screen Settings: Many devices offer features like "Night Mode" or "Blue Light Filters" that reduce the amount of blue light emitted during evening hours. Enabling these settings can be beneficial in minimizing the impact on circadian rhythms.
2. Taking Breaks: Implement the 20-20-20 rule—every 20 minutes, look at something 20 feet away for at least 20 seconds. 
3. Investing in Blue Light Glasses: Specialized glasses with blue light filtering coatings are available to reduce the amount of blue light that reaches your eyes. 
4. Creating a Sleep-Friendly Environment: Minimize screen time at least an hour before bedtime.
