What is Blu-ray?

Blue light is high-energy visible light with a wave length between 380 and 500 nm. It is the most powerful light in visible lights. Blu-ray is common in mobile phones, computers, projectors, LED displays, and movie screens, etc.
Blu-ray has great harm to people’s eyes. When watching TV, computer, mobile phone, etc. for a long time, the eyes will have symptoms such as fatigue, dryness and tingling, etc. Blue light will increase the toxin in the macular area of the eye, seriously threatening eye health, even inducing blind eye disease.
Blu-ray can easily penetrate the skin and cause more free radicals in the skin. It is another major culprit in skin aging.

The harm of Blu-ray to the skin:

1. Blu-ray can cause macula and freckles:
Blu-ray penetrates the skin more strongly than ultraviolet light. Continuous use of high-brightness screen for 3 hours is equivalent to exposure to the sun for 1 hour, so your eyes will be sore, the skin will dry out, and it will stimulate the production of melanin (melanin’s main function is to resist UV rays), when it is resistant to UV rays, melanin will become flaking and stick to the surface of the skin to form macula and freckles.

2. Blu-ray can cause skin aging:
Blu-ray can penetrate the epidermis and dermis of the skin, causing serious damage to the mitochondria in the epithelial cells, reducing the activity of the mitochondria, the “generator” of the human skin cells. The decrease in mitochondrial activity directly causes aerobic free radicals abnormally active in the skin. In the process of aerobic free radicals’ continuous proliferation, a large number of matrix metalloproteinases (MMPs) are continuously released. Matrix metalloproteinases are the main culprit in the loss of human collagen and the root cause of skin aging and wrinkles (the latest international theory).

3. Blu-ray can cause skin irritation:
The light emitted by the Blu-ray is close to the intensity of the ultraviolet rays in the midday sun. The strong light stimulates the cerebral cortex, inhibits the secretion of melatonin, improves the body’s excitement, and stimulates the production of adrenocortical hormone. The adrenal cortex hormone directly causes the human body’s immunity to drop sharply and endocrine disorders. Reduction of the body’s immunity directly caused skin redness, swelling, dry peeling, tightness, itching, blisters, small pimples, small red spots and other allergies.

4. Blu-ray can affect sleep quality:
Nowadays, many people have the habit of watching mobile phones, IPads, computers and televisions before going to bed. The Blu-ray from these electronic products is very strong, and at a close range it can cause damage to the retina and seriously affect the secretion of melatonin (improving sleep factors). Blu-ray stimulates the brain, inhibits melatonin secretion, and increases the production of adrenocortical hormone, thereby destroying the balance of hormone secretion and directly affecting sleep quality.
Insufficient sleep or low sleep quality not only affects the quality of the skin, but also directly leads to decreased ability on immune function, responsiveness, memory and coordination. The risk of heart disease, cancer, obesity, indigestion, constipation, depression and other diseases increases.
