Fluorescent lights emitting
WebA study in 2011 also found evidence that the transition from incandescent to fluorescent lighting had a big impact on eye health (1). Fluorescent lighting above 4000K is dangerous for the eye, and at 6000K it can cause damage to the retina. Conventional LEDs that emit high-intensity blue light also have a major impact on eye health.
