"Blue light" silently harms the eyes.

      In the present time, it is undeniable that people of all genders and ages live their lives online almost all day long. Whether it's online learning, online meetings, online shopping, or Line chat, we encounter blue light from various sources every day, especially from electronic devices such as smartphones or computer screens. Today, we would like to share the side effects of blue light with everyone.

• Disrupting Circadian Rhythm: If exposed to blue light from screens at night, it affects the Circadian Rhythm or the body's internal clock, resulting in difficulties falling asleep and a feeling of inadequate rest.
• Eye Fatigue: Due to the high brightness of the blue light we are exposed to, our eyes have to work harder.
• Dry Eyes: Most devices we look at are small in size, leading to more frequent blinking than usual.
• Eye Nerve Damage: Blue light can penetrate and damage light-receptive cells in the retina, resulting in a deterioration of central vision.

      Blue light filtering glasses can help reduce the entry of blue light into the eyes. However, they may not always be necessary since every color wavelength of light has potential risks to the eyes. By creating a suitable environment and adjusting our eye usage habits, we can help prevent dangers and maintain the health of our eyes.
