We rely on technology for many aspects of our lives, from reading e-mails to streaming movies and music. However, electronic devices like smartphones and laptops emit blue light that can negatively impact your eye health after extended exposure. Below is a comprehensive overview of how blue light affects the eyes and what you can do to limit your exposure.

What Is Blue Light?

Sunlight contains a spectrum of light rays, including red, orange, yellow, green, and blue. Blue light rays are on one end of the spectrum; they have the shortest wavelengths but the highest energy. Many indoor sources of lighting contain blue light, such as LED lighting, computers, televisions, tablets, and smartphones.

How Does Blue Light Affect Eye Health?

Constant exposure to blue light from electronics can be harmful in the long run. When the energy from blue light passes through the cornea, it harms the cells in the retina. This can lead to problems like digital eye strain, which occurs after staring at a screen for too long. Symptoms include dry eyes, irritation, and difficulty focusing. Long-term health issues may include macular degeneration, which is the leading cause of blindness in senior adults. 

How Can I Limit Blue Light Exposure?

The best way to reduce exposure is by taking routine breaks from screens. You can also install a screen filter for your phone, tablet, or computer that will decrease the amount of blue light being emitted. Computer glasses with yellow-tinted lenses also block out blue light to prevent symptoms of digital eye strain.
