Understanding Blue Light

PeakVision Sunglasses Naturally Protect You From Blue Light

Blue light is a high-energy visible (HEV) light that falls within the 380–500 nanometer wavelength range. It is emitted by both natural sources, like the sun, and artificial sources, such as LED screens, smartphones, and computer monitors. While some blue light exposure is necessary for regulating sleep cycles and boosting alertness, excessive exposure, especially from the sun, can have negative effects on eye health.

How the Sun's Blue Light Can Contribute to Eye Disease

The sun is the largest source of blue light exposure, and over time, excessive exposure has been linked to potential eye diseases such as:

• Macular Degeneration: Long-term blue light exposure from the sun can contribute to oxidative stress on the retina, a key factor in age-related macular degeneration (AMD), which can lead to vision loss.
  
• Cataracts: Some studies suggest that cumulative blue light exposure may accelerate the development of cataracts, a clouding of the eye’s lens that impairs vision.
• Eye Strain and Fatigue: Blue light scatters more easily than other wavelengths, making it harder for the eye to focus and contributing to digital eye strain and discomfort.

Natural Blue Light Protection

At PeakVision, our sunglasses aren’t specifically marketed as blue light blockers, but they naturally filter harmful blue light thanks to our amber-colored lenses. This tint absorbs a portion of blue light from the sun, reducing glare and helping to minimize potential eye strain caused by prolonged exposure. Our Dual Zone lens technology, designed for high-performance sports and outdoor activities, provides an added layer of protection against both UV rays and HEV blue light without distorting vision.

Amber Lenses Also Block Blue Light from Screens

According to the AMDF, blue light from electronic devices has not been definitively linked to eye disease. However, some people in general have reported experiencing discomfort and eye strain after prolonged screen time. Coincidentally, the amber lens tint in PeakVision sunglasses also filters blue light emitted from screens, providing an added benefit for those who are concerned about long-term screen exposure. This means that whether you’re out on the golf course or working on a computer, PeakVision sunglasses help reduce blue light exposure in both natural and artificial environments.

The PeakVision Difference

PeakVision’s lenses go beyond simple glare reduction, they provide high-contrast vision, superior clarity, and built-in blue light filtration, making them an ideal choice for anyone who spends extended time outdoors or wants extra peace of mind when it comes to screen exposure. While we don’t advertise our sunglasses as blue light blocking glasses, the science behind our lenses speaks for itself. Protect your eyes naturally with PeakVision’s advanced lens technology, whether you're on the course, on the water, or behind a screen.
