What is phone blue light and how is excessive use harmful to us
Phone blue light is the high-energy visible (HEV) light that digital screens, like computers, phones, and tablets, give off. Blue light has shorter wavelengths than other types of light, which lets it reach deeper into the eye. Blue light from the sun during the day helps keep our sleep-wake cycles in balance. But too much time in front of a screen, especially at night, can keep you up at night and cause digital eye pain.
High energy: Blue light has extra energy because its bands are short.
It can reach the retina and may do damage that lasts for a long time.
Blue light main Sources Digital screens and LED lights are the main sources.
What Blue phone Light Is Made Of
To understand how phone blue light affects our health, we need to know what it looks like. There are different types of visible light, but blue light has the smallest wavelengths and the most energy. Because of this, it can go deeper into the eyes and reach the retina. During the day, blue light helps keep our circadian rhythms in balance. But at night, too much exposure can be bad for your health and cause a number of problems.
Wavelength and Energy: Blue light has a short wavelength and a lot of energy, which makes it more intense.
Source: Devices like computers, smartphones, and LED lights give off this gas.
Structure of phone and other gadgets blue light
Phone blue light refers to the high-energy visible (HEV) light that falls within the blue spectrum, typically ranging from 380 to 500 nanometres. This type of light is emitted by various digital screens, including smartphones, tablets, computers, and televisions. While blue light is a natural part of sunlight and plays a crucial role in regulating our circadian rhythms, excessive exposure to artificial blue light from screens can lead to various health issues.

How does phone Blue Light affect to Our Health
Many health issues can happen when you are exposed to too much phone blue light. To begin, it can cause digital eye strain, a disease that makes the eyes hurt and itch. Blue light also makes it hard to sleep because it stops the production of melatonin, a hormone that controls sleep. Being exposed to blue light for a long time may even damage the eye, which raises the risk of age-related macular degeneration.
Dry eyes, itching, and blurred vision can happen after staring at a screen for a long time.
messed-up sleep patterns: stop the production of melatonin, which makes it harder to fall asleep.
Damage to the retina: Long-term exposure may raise the chance of eye diseases like macular degeneration.
Skin Ageing: Blue light can cause reactive stress, which makes skin wrinkle and age faster.
Why a phone digital detox is important
During a phone digital detox, you intentionally spend less time in front of screens to lower your blue light exposure. These breaks help people feel better overall and relieve worry and anxiety. A daily digital detox can also help your eyes and sleep by giving your eyes a break from staring at screens for long periods of time.
Better Sleep: Spending less time in front of a screen before bed helps your body make melatonin naturally.

Oxidative Stress: Free radicals are made by blue light, which hurts the skin.
Hyperpigmentation: Long-term contact can make your skin get dark spots or an uneven colour.
Breakdown of Collagen: Blue light speeds up the breakdown of collagen, which causes lines and wrinkles.
