What Is Blue Light And How Does It Affect My Eyes?
Blue light is a type of high-energy visible (HEV) light with a wavelength of around 400-450 nanometers, which is on the higher end of the visible light spectrum. It’s emitted by digital devices such as smartphones, tablets, and televisions, and can cause eye strain, fatigue, and discomfort.
Prolonged exposure to blue light has also been linked to disrupted sleep patterns, as it can suppress the production of melatonin, the hormone responsible for regulating our sleep-wake cycles. This is why it’s essential to take steps to minimize blue light exposure, especially in the evening or when watching TV for extended periods.
How Does A Blue Light Filter Work On A TV?
A blue light filter on a TV works by reducing or eliminating the emission of blue light from the screen. This is typically achieved through software or hardware modifications that adjust the TV’s color temperature and brightness. Some TVs have a dedicated blue light filtering mode, while others may offer customizable color settings that allow you to adjust the amount of blue light emitted.
When a blue light filter is enabled, the TV’s screen will often take on a warmer tone, which can make it more comfortable to watch for extended periods. This can be especially beneficial for people who experience eye strain or fatigue when watching TV, or for those who like to watch TV before bedtime.
