Pay Attention To Children's And Adolescents Eye Health

Anti-Blue-ray glasses manufacturers pay attention to the visual system of children and adolescents.  As children and adolescents are in a sensitive period of human visual system development, the lens is not yet well developed, the lens of the human eye will slowly turn yellow with age, and the yellowing process helps to filter blue light.

However, because the infant's lens is very clear, it cannot effectively filter blue light like adults, directly passing through the corners, membranes and lenses to reach the retina, and they are more vulnerable to blue light.

In addition, the number of blue light injected into the eyeball has different proportions at different ages.

Generally speaking, 0 to 2 years old, about 70% to 80%; 2 to 10 years old, about 60% to 70%; 60 to 90 years old, about 20%.

It can be seen that the greatest harm of blue light often occurs at the initial stage of human life, so parents of infants and young children need to guard against the damage that blue light may cause to the eye health of infants and young children. What is blue light?

Blue light does not mean blue light, but a wavelength of 380-

500 nm high-energy visible light is the strongest light in visible light.

Blue light is an important part of visible light.  There is no single white light in nature.  Blue light is mixed with green light and yellow light to show white light.

Green light and yellow light have less energy, less irritation to eyes, short blue light wave and high energy, and can directly penetrate the crystal to reach the fundus retina. What things in life will emit blue light?

All kinds of computers, TV screens, energy-saving lamps, camera flash lamps, Yuba light and other new artificial light sources and visible light emitted by sunlight contain a large amount of short-wave blue light with irregular frequencies.

According to research, blue light can penetrate the cornea and lens to reach the retina, causing the death of light-sensing cells first, accelerating the oxidation of macular cells, causing retinal macular degeneration, and then causing gradual decline or even complete loss of vision, this kind of injury is often irreversible.

The damage effect of high-energy blue light is a chain reaction, and its damage to eyes is gradually accumulated.

Even if you don't look directly at the light source, it will hurt your eyes for a long time.

In addition, blue light also inhibits melatonin secretion and disturbs sleep.
