DID YOU KNOW?
Sunlight is a wave of electromagnetic radiation released by the sun. It consists of 50% infrared, 40% of visible and 10% of ultraviolet light.
The sunlight's energy contains about 52-55% of infrared (above 700nm), 42-43% of visible light (400-700nm) and 3-5% of ultraviolet light (below 400nm).
THE DANGER OF INFRARED, BLUE AND UV LIGHT
Exposure to infrared, blue and ultraviolet light can cause damage to the eyes. The human eyes can only tolerate limited amount of electromagnetic radiation. Various lights can have different effects on the eyes.
Below are some of the damages that harmful lights can cause:
◆ Near Infrared light between (780nm - 1400nm) increases damage to the lens and retina.
◆ Blue light can cause damage to the retina.
◆ Ultraviolet light may trigger eye diseases developing in the cornea.
21RAY IS THE SOLUTION
The Advantages of 21 RAY
21RAY is the only lens that can effectively block out harmful near infrared lights, as a result this reduces the temperature in the eye.
This is fundamental to decrease the risks of eye damage associated with inflammation in the eye.
21RAY blocks off infrared, blue and UV light while also allowing beneficial light to pass through the lens to provide a clear and natural vision.
