Light is either invisible (ultraviolet, aka UV rays) or visible. Blue light has the shortest wavelength in the visible light spectrum, meaning it contains the most energy. The sun used to be our only source of blue light, but now LED and fluorescent lighting, along with electronic devices and digital screens (found on cell phones, computers, tablets, TVs, and gaming consoles) have increased our exposure to high-energy blue light.
Blue light is a significant factor in your circadian rhythm (your body's internal clock). Exposure to blue light via sunlight throughout the day helps synchronize your body's natural processes. Research suggests that a poor circadian rhythm may play a role in disrupted sleep cycles, tumoral diseases, diabetes, obesity, and depression.
Most people are exposed to excess blue light on a daily basis, which can have a negative impact on your circadian rhythm and may lead to other issues such as:
People who work on computers all day have a higher risk for digital eye strain and other related ocular conditions due to increased blue light exposure from their computer screens.
Research on the effects of blue light blockers is limited because this issue is novel. However, studies have shown that eyewear with blue light filters are an effective treatment for LED-induced melatonin suppression.
Many eye doctors and patients have reported decreased digital eye strain and an increased ability to focus in people who have high screen times. Though it is unproved, blue blockers may also help prevent against ocular conditions such as macular degeneration, as well as other serious health conditions.
