How Does Blue Light Affect My Eyes?

Apr 14, 2023

In today’s world, we spend more time than ever before in front of digital screens, from computers to smartphones and TVs. While digital screens have made our lives easier and more convenient, they also expose our eyes to the harmful effects of blue light. In this blog post, we will discuss how blue light affects our eyes and what we can do to protect them.

What is blue light?

Blue light is a type of light with a short wavelength that emits high energy. It is found in natural sunlight, but it is also emitted by digital screens, such as smartphones, laptops, tablets, and TVs. While blue light is not inherently harmful, excessive exposure can negatively impact the eyes.

How does blue light damage my eyes?

Prolonged exposure to blue light can cause digital eye strain, which results in symptoms like headaches, blurred vision, dry eyes, and eye fatigue. Blue light exposure can also disrupt the natural sleep-wake cycle, leading to difficulty falling asleep or staying asleep.

Long-term exposure to blue light may contribute to age-related macular degeneration (AMD), which is a leading cause of vision loss among older adults. It can also lead to the development of cataracts, which cause clouding of the eye’s natural lens.

How can I protect my eyes from blue light?

-Use blue light filters or screen protectors: Blue light filters or screen protectors can reduce the amount of blue light emitted by digital screens. Some devices also come with built-in blue light filters that you can turn on.

-Adjust the display settings: Most digital devices allow you to adjust the display settings to reduce blue light emissions. For example, you can adjust the brightness or color temperature to reduce the amount of blue light emitted.

-Take frequent breaks: It’s essential to take frequent breaks from digital screens to give your eyes a rest. Follow the 20-20-20 rule, which recommends taking a 20-second break every 20 minutes to look at an object 20 feet away.

-Wear blue light-blocking glasses: Blue light-blocking glasses are specially designed to block blue light emissions from digital screens. They can be worn while using digital devices or during the day to reduce overall blue light exposure.

-Use night mode: Many digital devices now have a night mode that reduces blue light emissions and creates a warmer, more relaxing color temperature. This setting is ideal for using devices before bed.

While there’s no avoiding using digital screens in our daily lives, we can protect our eyes and prevent digital eye strain and other eye problems. By taking proactive measures to reduce blue light exposure and scheduling regular eye exams, we can keep our eyes healthy for years to come! If you have any concerns about your vision or eye health, don’t hesitate to schedule an eye exam with our eye doctors in Newport, ME, or Waterville, ME!
