The terms “blue light blocking” and “blue light filtering” are often used interchangeably in the market, but they can imply different levels of protection. “Blue light filtering” generally refers to lenses that selectively reduce the intensity of specific wavelengths of blue light, typically those considered most disruptive, often within the 400-450nm range. These lenses may have a visible tint, such as yellow or amber, which indicates the presence of a filtering agent.
“Blue light blocking” can sometimes suggest a more comprehensive or complete elimination of blue light. However, it’s important to note that completely blocking all blue light is generally not desirable, as blue light from natural sunlight plays a vital role in regulating our circadian rhythm and mood. Many reputable brands use the term “filtering” to accurately describe their product’s function, which is to selectively reduce blue light exposure rather than block it entirely. When evaluating products, it’s beneficial to look for specifications on the percentage of blue light blocked and the specific wavelength range targeted.
