Most Americans unaware of all sources of blue light

A consumer survey from Transitions Optical found that the majority of Americans do not know that sunlight, digital devices and screens, and fluorescent and incandescent light bulbs are all sources of harmful blue light.

The survey, conducted by Wakefield Research and discussed in a press release from Transitions, asked participants to identify which types of light can cause long-term harm to eyes. Seventy-six percent identified sunlight, while 61% additionally answered light from digital screens.

However, only 4% correctly identified all common sources of blue light, including digital devices and screens, fluorescent lights, incandescent light bulbs and sunlight. General awareness of blue light and its potential impact was also in the minority, as only 17% of those surveyed recognized the sun as a source of harmful blue light, despite it emitting more than 100 times the intensity of electronic devices and screens, according to the release.

“Even though discussions around the dangers of harmful blue light are at the public forefront, we are finding that many people are misinformed about the sources of harmful blue light,” Patience Cook, director of North America marketing for Transitions Optical, said in the release. “The research suggests that many Americans associate blue light with long-term damage to the eyes. Eye care professionals should be ready to discuss this topic of concern and recommend products that offer blue light filtering benefits that appeal to today’s modern lifestyle.”

In an effort to raise awareness of blue light, Transitions Optical has released new education materials for professionals, including an educational training video, quick study guide and brief training presentation, on its company website.
