One problem that many people find with fluorescent lighting is the strobe/flicker of the light, which is caused by a device called the ballast. The ballast helps regulate the amount of light coming from the bulb, but the flickering that they cause can strain your eyes and cause headaches. Even though many people don’t see the flicker unless they’re focusing on it, the strain that occurs when your brain tries to process the flicker can cause stress, fatigue, and headaches. The flickering also makes your pupils work extra hard to adapt to the varying level of light. Because LED lighting doesn’t need a ballast, and uses DC current, it is far more healthy to your eyes. This reduction in flickering can also help reduce the stress and headaches related to the strobe effect.
