Is SSL Blue Light Bad for Your Health?

Hear from our experts on Everything LED Lighting

Since the inception of solid-state lighting (SSL) such as LEDs, there has been concern over the risks and health effects it may have on the human eyes and body. Traditionally, this concern has been linked to the more well-known SSL blue light. If not thought to damage health and eye safety, bluer LED lights in streetlights, headlights, and more have been touted as too bright, annoying, and hard on the eyes. But is there any real risk to blue SSL light in comparison to traditional lighting on the market? Let’s find out!

Solid State Lighting Health Concerns and Risk Assessment

Today, before SSL lights hit the mass market, they must meet the requirements of the “Photobiological safety of lamps and lamp systems” classification. What does this standard entail?

This standard points to two specific possible health hazards caused by any visible light, not just SSL emitted light. The first is retinal burns, which can be avoided by normal aversion (a.k.a. don’t look directly at the sun). The big question in regards to SSL blue light is whether it is more damaging to retinas than traditional light bulbs.

SSL vs Traditional Lighting Health Effects

Accurate testing is very difficult in these situations and is based on equipment used, subjects, environment, etc. The end goal is to associate a risk level with a light source, ranging from 0 (no risk) to 3 (dangerous). Risk levels 1 and 2 are not dangerous when avoided using aversion and normal behavior.

Is One Better or Worse?

Studies show there is no difference in risk class when comparing SSL, or LED, lighting and traditional sources. The majority of both fall under risk class 1, with few LEDs falling under risk class 2. Any damage or health risk can be averted with normal behavior.
