Eyesafe | Blue Light & Color Standards
Blue light and color standards for Eyesafe technology including ANSI Z80 and Z87 blue light and CIE color standards. These standards provide information on blue light coverage levels across the light spectrum and color quality.

As you look for products that filter blue light, it is always best to focus attention on those companies that base their product development efforts on scientific standards pertaining to the segmentation and transmission of blue light

Blue Light & Color Standards

 

Visible light spans the electromagnetic spectrum between 380 and 780 nanometers (nm). Within the light spectrum, blue light, which is also referred to as high-energy visible (HEV) light, has wavelengths between 380 and 500nm. The high-energy section of the visible spectrum affects our eyesight because this light passes through the cornea at the front of the eye and reaches the retina at the back of the eye. There, HEV light can produce negative eye health consequences, including digital vision syndrome, melatonin suppression, and long-term effects on the retina that could lead to potential increases in age-related macular degeneration and cataracts. To date, there are no published standards on the cumulative effects of HEV blue light exposure, but significant research and scientific papers have been generated on the impact that HEV blue light has on the eyes.

 

Eyesafe® technologies, from Healthe, are focused on selectively blocking UV and HEV light that is emitted by digital devices. We rely on two updated 2015 standards from the American National Standards Institute (ANSI) to guide our product development: Z80.3 and Z87.1.

 

ANSI Z80.3 Nonprescription Sunglasses and Fashion Eyewear Requirements

 

The US ANSI Z80.3 standard for sunglasses was updated in 2015. As shown in this table, it includes data for computing blue light transmittance.

 

Z87.1-2015: American National Standard Occupational and Educational Personal Eye and Face Protection Devices

In addition to Z80.3-2015, we also consider ANSI Z87.1-2015, which identifies the wavelengths of blue light hazard and identifies a peak Hazard Factor at 435nm to 440nm. Eyesafe produces technologies that selectively filter specific UV and blue light wavelengths. If you would like to review these standards in full, you can purchase and download them here.

Color Management and User Experience

At Healthe, we are very cognizant of the impact that blue light filtering has on color transmission. In fact, it is a primary goal of all Eyesafe technologies to selectively filter blue light while maintaining crisp and vivid color transmission in digital displays.

 

The CIE (International Commission on Illumination) 1931 color spaces were the first defined quantitative links between physical pure colors (i.e. wavelengths) in the electromagnetic visible spectrum, and the physiological perceived colors in human color vision. The mathematical relationships that define these color spaces are essential tools for color management when dealing with color inks, illuminated displays, and recording devices such as digital cameras. Many digital devices, whether they are phones, tablets or monitors, strive to create an illumination rating known as D65. The CIE positions D65 as the standard daylight illuminant, and is intended to represent average daylight. As we filter blue light from display emissions, we also strive to minimally impact D65 illumination ratings.

The Eyesafe® brand of protective products adheres to the published standards by ANSI while maintaining color transmission as prescribed by CIE. As such, we ensure we are creating a product that not only selectively filters blue light, but also maintains CIE color transmission and D65 illumination ratings.
