Commonly used computers can also wear protective glasses

In today's digital age, electronic devices have become an essential part of our daily lives. With the rapid development of mobile internet, smartphones and computers are now indispensable tools for work, communication, and entertainment. However, prolonged exposure to these screens can lead to various eye-related issues over time. To protect your vision, it's important to choose the right type of protective glasses. Here are some tips to help you make an informed decision:

Understanding the Risks

The primary cause of eye strain from computer and phone screens is the harmful effects of blue light and ultraviolet rays emitted by these devices. These types of light can damage the retina over time, especially when exposed for long periods. Protecting your eyes from both blue light and UV radiation is crucial for maintaining good visual health.

Additionally, the flickering or screen instability of many digital devices can cause your eyes to constantly adjust focus, leading to increased fatigue. According to a report by Japan’s NHK, blue light from LCD screens—common in computers, smartphones, and tablets—can contribute to eye fatigue, disrupt sleep patterns, and even affect overall health. As more people spend hours in front of these screens, medical professionals are increasingly concerned about the long-term consequences.

A Japanese research institute specializing in blue light highlights that blue light has the shortest wavelength and highest energy among visible light, making it particularly taxing on the eyes. Prolonged exposure may lead to retinal inflammation, while exposure at night can interfere with melatonin production, disrupting sleep cycles. Other studies suggest that blue light could be a contributing factor to age-related macular degeneration, a serious condition affecting central vision. "We believe that blue light not only causes eye discomfort but also impacts the body’s internal clock," said Ichiro Hirotaka, chairperson of the Blue Light Research Association and professor at Keio University School of Medicine. "We will continue to study its effects on both the eyes and overall health."

Effective Ways to Protect Your Eyes

1. Take regular breaks: Every hour, step away from your screen for a few minutes to rest your eyes. This simple habit can significantly reduce eye strain and prevent long-term damage.

2. Use blue light filtering glasses: Opt for high-quality computer glasses that effectively block harmful blue light. For example, German-made haze glasses are designed specifically for this purpose. Blue light is known to increase eye fatigue and cause damage to visual cells, so filtering it can help reduce discomfort and prevent long-term harm. Not only does this help relieve symptoms like dryness and pain, but it also reduces eye fatigue and protects your vision in the long run.
