Typically, we associate blue light with negative connotations, such as a sleep-sucking vampire. However, there are some benefits to blue light and it can be a helpful addition to your daily routine. However, too much exposure can be harmful to your health, especially if you use digital devices for a long period of time.
Blue light is produced by the sun and fluorescent light bulbs. It is also emitted by LED lights in computers, tablets, and cell phones. However, studies have shown that too much blue light can interfere with sleep and health.
Blue light is a form of high-energy visible light. It can boost your mood, improve your memory, and support cognitive function. However, it has been linked to cancer and can also damage light-sensitive cells, such as the retina. While the effects of blue light are still being investigated, scientists are concerned that too much exposure can lead to long-term health problems.
Blue light can also affect your skin. Research suggests that glare from LED screens can age your skin and disrupt your mood. For this reason, many doctors recommend using special bluelight filter glasses when using electronic devices for extended periods of time. The light also interferes with the production of melatonin, a hormone that helps regulate your sleep cycles. While blue light may not cause permanent eye damage, it is believed that it can cause inflammation of the eye’s conjunctiva. It can also irritate the cornea.
Researchers have found that blue light in the evenings can actually decrease the amount of melatonin secreted by the body. This in turn reduces the duration of sleep. According to a study by the University of Haifa, people who were exposed to blue light before bed had a 16-minute shorter sleep than people who had no exposure to the light. If you’re worried about your sleep, you can use the 20-20-20 method to relax your eyes. This involves looking at something 20 feet away for 20 seconds for every 20 minutes you spend looking at a screen. If you have trouble falling asleep, you may also find it helpful to switch to an amber-light mode.
According to a recent study, exposure to Blue Light can also increase your risk of photo retinitis, an eye condition that causes the retina to become damaged and lose its color. However, too much exposure to Blue Light is also linked to an increased risk of macular degeneration, which causes damage to the macula, the part of the retina that allows us to see details in the center of our field of vision. This condition is the leading cause of sight loss in people over the age of 50.
Some experts recommend switching your device off at least 30 minutes before going to bed. While this may not be possible for everyone, it may help you sleep better. The American Academy of Ophthalmology (AAO) also recommends taking breaks when using digital devices for extended periods of time.
