IKYUM® BLUEBLOCKER
a must-have
BLUE LIGHT filter
Modern world makes us spend a lot of time working or resting in front of our devices and other screens. IKYUM® Clarity Blueblocker Glasses are a trendy way to prevent and reduce blue light exposure while also improving your quality of life.
Blue light is everywhere
Blue light is primarily emitted by sunlight, and we are mostly exposed to it when we are outside during the day. But there are many other sources of blue light, including LED lighting, mobile devices, tablets and other screens..
Visible wavelength
light spectrum
The color of each ray of light depends on its energy and its wavelength. To make it simple, the three primary colors are: red, green, blue. By combining these three colors it allows to see the white light. If we go into more detail, all the colors of the spectrum (violet, blue, green, yellow, orange and red) give us the white light of the day that we perceive. Isaac Newton, an English physicist, demonstrated in 1666 that white light is a mixture of 6 colors. To associate the number 7 with his discovery, he added an Indigo color. The number 7 is thought to be magical.
The human eye perceives radiation between 380nm (blue) to 700nm (red). Beyond these two extremes, we speak of the invisible wavelength.
INVISIBLE Ernergetic light
below 380nm
The particularity that interests us for our eyes are the frequencies
below 380nm on the blue side (Ultra-Violet-UV). These rays, invisible to the human eye, are of very short wavelength and very energetic. We all know the importance of sunglasses and sun cream that we apply to our skin to avoid the harmful impact of UV.
On the other side of the light spectrum, the rays above 700nm (Infrared | IR) are also part of the invisible light but are not as energetic as UV. Paradoxically, these rays (IR) produce heat but do not modify the DNA structure of our cells, unlike UV. For example, in the sun you feel the value of IR but it is the UV that gives you sunburn impacting your skin's health.
What about digital radiation
wavelengths of discord
Screens, LED bulbs, tablets and smartphones emit visible blue light located between 380nm and 500nm. The amount of blue light emit by our devices is only a fraction of that emitted by sunlight. But given the amount of time we spend in front of these screens, many ophthalmologists and other health professionals are concerned about the long-term effects on our eye health.
Further research is still needed to identify how much natural and artificial blue light from sunshine and digital devices is too much for the retina.
scientifically proven
Blue Ligh disrupts our sleep
There is some doubt about the long-term harmful effects of overexposure to this high-energy visible light. Studies are underway to scientifically define its real impact on the human eye. One thing we do know for sure scientifically is that the blue light emitted by our various screens stimulates a hormone that disrupts our sleep.
Most of the optical lenses (non-sunglasses) commonly sold on the market absorb radiation up to 370nm. At IKYUM®, we decided against taking risks for our clients. We are proud to propose optionally a BlueBlocker UV 410 filter.
