At Peepers, we’re committed to providing exceptional products that not only deliver incredible style, but also do more to protect and enhance your vision. Form and function both receive our highest level of attention with every product we design.
This is why we’re proud to announce that all of the new styles in our latest collection, and all styles moving forward, will be part of our Focus™ Eyewear line featuring lenses that filter and minimize the effects of harmful high-energy blue light.
What is HEV Blue Light?
The blue light portion of the electromagnetic spectrum ranges from 380-500 nanometers (nm). The 400-450nm range, known as high-energy visible (HEV) light, is considered by researchers to be the most harmful to our eyes. Blue light features a short wavelength, which coincides with higher energy products, and exposure to this light could lead to ocular damage over time.
Many electronic devices, such as cell phones, computers, laptops, tablets, and TVs, emit light in this range, and modern users spend more and more time looking at these devices. In fact, blue light also comes from the sun, as well as lighting sources like fluorescent and LED lights. It’s all around us.
Why is it Harmful?
The problem with blue light is the short wavelength and high energy associated with it. These factors result in light that flickers more than other portions of the electromagnetic spectrum, and extensive exposure to this effect could result in undesirable symptoms such as eye strain, headaches, fatigue, sleep disruption—the list goes on.
Research is not yet clear on the long-term effects, although it is possible that significant exposure could contribute to issues like age-related macular degeneration as well as health issues tied to poor sleeping habits over a long period of time.
Peepers Focus™ Eyewear Lenses
While blue light cannot be eliminated, it can be minimized, and we can take steps to protect our eyes against harm from HEV blue light. In an effort to deliver eyewear that meets both functional and aesthetic preferences, Peepers offers blue light filtering lenses in the Focus™ Eyewear line that filter 40% of the most harmful HEV blue light (between 400-450nm), including over 98% filtering at 410nm and 63% at 420nm. In addition, our Focus™ Eyewear lenses offer a seven-layer anti-reflective coating and UV400 sun protection, the same level of UVA/UVB protection you’ll enjoy with our sunglasses.
Some eyewear companies advertise that their products block 100% of blue light, but this can be a misleading claim. Remember that although the blue light spectrum ranges from 380-500nm, the most harmful high-energy portion is 400-450nm. In order to block 100% in the HEV range, lenses would have to be yellow or orange. Be sure to pay close attention to the range your favorite eyewear is claiming to block! Your lenses may be blocking 100% of less harmful blue light but falling short on protection where it counts most.
All of this helps to guard your eyes from several of the most common threats in the modern environment, reducing symptoms and risk factors so that you can prevent damage to your vision and look great doing it.
