Staring at digital screens often leads to tired eyes, blurred vision and headaches, but can also cause eye damage. Knowing the risks and how to safeguard your eyes from harmful blue light is important.
How harmful blue light affects your eyes
Not all blue light is bad. For example, sunlight is the main source of blue light, and being outdoors during daylight is where most of us get most of our exposure. However, the world has become largely reliant on smartphones, tablets and laptops — technologies with displays that often produce large amounts of blue light. The long-term effects may be harmful. In fact, harmful blue light or blue-violet light can be damaging to delicate retinal cells deep in the eye. Additionally, studies have shown harmful blue light is a risk factor for the onset of age-related macular degeneration, a progressive condition that can lead to vision loss over time.
Specialized lenses can help
One of the ways you can protect your eyes, is to selectively filter the blue light around you so your eyes receive good light, while at the same time reducing your exposure to bad blue light. Today, the technology exists to create lenses embedded with a specialized filter to help reduce exposure to harmful blue light. These premium lenses can be made specifically to meet the needs of your lifestyle.
