Which is more eye-protecting, led lamp or incandescent lamp?

LED lights are more eye-protecting. Because the light-emitting principle of LED lamp is realized by electronic transition, it will not produce ultraviolet and infrared rays, and the brightness is uniform, the color temperature is lower, which is closer to natural light and less irritating to eyes, so it is more suitable for long-term use. The luminous principle of incandescent lamp is realized by heating metal wire, which will produce a lot of thermal radiation and infrared rays, which will easily cause eye fatigue and dryness.
