What is blue light and how it is affecting you? - Livho glasses

 

Blue light is all around you and has a massive impact on your daily life! Blue light is a color in the visible light spectrum that the human eye can see. Because of blue light’ s short wavelength, it has a massive energy output. Blue light can cause eyestrain, weariness, headaches, and insomnia if you get too much exposure.

Everything you need to know about blue light (Energy, Strengths, Colors, and Wavelengths)

Electromagnetic particles that travel in waves make up light. These energy-emitting waves come in a variety of lengths and strengths. The higher the energy, the shorter the wavelength. Blue light has a wavelength of 380 - 500 nm. Wavelength is measured in nanometers (nm), where 1 nanometer equals one-billionth of a meter. Each wavelength is represented by another color and is classified as gamma rays, x-rays, ultraviolet (UV) rays, visible light, infrared light, or radio waves. The electromagnetic spectrum is made up of all of these wavelengths combined.

On the other hand, the human eye is only sensitive to one part of this spectrum: visible light. Indigo, violet, green, blue, red, orange and yellow are examples of visible light from the electromagnetic spectrum. Because blue light has a small wavelength, it produces a lot of energy. According to studies, exposure to the blue end of the light spectrum may cause substantial long-term harm to your eyes.

Sources of blue light

  • Sunlight
  • Fluorescent light 
  • LED lighting 
  • Digital devices       


Anti Blue light glasses are made to filter out the hazardous blue-violet light rays emitted by digital screens. 

Natural blue light is very important for your health and you need to get enough exposure to natural blue light every day. However artificial blue light is not good for your eyes. In fact, artificial blue light damages your eyes and can cause various problems such as headaches, dry eyes, and red eyes. Blue light with a wavelength of 400-460 nm will do harm to your eyes while blue light in 470-500 nm will do a lot less. Artificial blue light cannot be avoided entirely but can be reduced by wearing anti-blue light glasses, spending less time on your digital devices, or changing the screen brightness settings on your device.

Benefits of blue light

·    Improve general mood and ease depression We can improve our alertness and energy levels during the day by exposing ourselves to blue light for at least an hour in the morning, especially from sunlight. In addition, seasonal affective disorder (SAD), a kind of depression, responds well to blue light therapy. Blue light is great for improving your mood and easing your depression!

·    People who live in the far northern and southern latitudes, when daylight hours are short during these months, are more likely to develop SAD in the fall and winter months. In addition, it has been discovered that an hour of morning exposure to blue-light-emitting lamps suppresses melatonin levels and improves SAD depression symptoms.

 

 

 

Summary

Blue light is all around us and is not something we can avoid entirely, but we can reduce it if we take the necessary precautions. Too much of a good thing is also bad and the same goes for blue light. Getting the right amount of blue light is important for our health but too much blue light exposure can be harmful to your eyes and health. We can reduce the amount of blue light we take in every day by spending less time on our digital devices, wearing blue-light-blocking glasses, and changing the light settings on our devices.

Experts: Blue light blocking glasses can hurt kids' eye health

 A group of ophthalmologists warned that having your child wear eyeglasses that block out blue light raises the risk that they will become nearsighted. There are no scientific grounds for recommending that kids use them.  The glasses can be harmful to the healthy development of children, given that a lack of exposure to sunlight, a large source of blue light, raises the risk of the progression of nearsightedness in children, the Japanese Ophthalmological Society and five other ophthalmology groups said in a joint statement on April 14. Blue light has a short wavelength and high energy, compared with other spectra, such as red and green, in the visible light spectrum. Companies are selling glasses that can block blue light from computer screens and smartphone displays to prevent eyestrain and eye damage. The group said that some published studies have suggested blue light disrupts our biological clock and that we are more likely to develop sleep disorders if we stare at the screens of s
