To reduce the hazards of blue light exposure, effective management strategies can be implemented, including limiting screen time before bed and using blue light filter. The blue light spectrum is an essential part of the visible spectrum with wavelengths of about 400-480 nm. [1]
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
When using any screen before bedtime, the blue light emitted disrupts the body's natural melatonin hormone production. [16] Melatonin is produced by the brain's pineal gland and controls the body's internal clock. [17] This clock is what is referred to as the body's circadian rhythm and it naturally is responsive to light. [18] Melatonin levels ...
Woman trying on blue light glasses. Even people who don't need eyeglasses for vision issues are donning specs these days. While some may be using non-prescription glasses as a fashion statement ...
Blue-light-blocking glasses are said to help reduce eye strain and headaches — are they for you?
Here are the best blue-light blocking glasses you can buy in 2023. Our experts are also revealing if they really work.
In humans, a lower intensity short wavelength (blue/violet) light appears to be equally effective as a higher intensity of white light. [11] Exposure to monochromatic light at the wavelengths of 460 nm and 550 nm on two control groups yielded results showing decreased sleepiness at 460 nm tested over two groups and a control group. Additionally ...
Experts recommend taking these little steps to increase your light exposure during the day and decrease blue light exposure at night: Take a short walk outside before work or during lunch. Grab ...
