Blue light in natural light

Blue light is not the unique light emitted by electronic products, but the visible light that exists in natural light, usually with a wavelength of about 400-500nm. The blue light in the entire waveband can be subdivided into two parts. One part will cause optical damage to the retina of the eye and accelerate the oxidative senescence of cells in the macular area of the retina. Usually, the wavelength of this part of blue light is between 415-450nm, and its damage to the eyes is gradually accumulated and formed. There is also a part of blue light that is beneficial to our human body, that is, blue light with a wavelength of about 480nm. It can adjust biological rhythms and is helpful for sleep, mood, and memory. In addition, experiments have confirmed that daily outdoor activities in the sun can effectively prevent the occurrence of myopia, and short-wavelength blue light may play an important role.

Polarized vs non-polarized sunglasses

  1. Non-polarized sunglasses generally only have the two basic functions of shielding strong light and filtering ultraviolet rays, and their efficiency in filtering ultraviolet rays is low. In our daily life, in addition to strong light and ultraviolet light, when light passes through uneven roads, water surfaces, and other places, irregular diffuse reflection light will be generated, which will cause blurred vision and fatigue in the eyes.

  2. Polarized sunglasses can filter out this kind of light, only absorb the reflected light of the object itself, truly present what you see, make the field of vision clearer, and reduce visual fatigue. In addition, polarized sunglasses have a 99% blocking rate of ultraviolet rays due to their high-efficiency filter layer, which can effectively reduce the damage of ultraviolet rays to the eyes.

  3. When judging whether the sunglasses are polarized lenses, you can rotate the sunglasses up to 45° clockwise. If the color of the lens changes at this time, and the color of the sunglasses returns to normal after turning the sunglasses back to the original position, then it can be judged that the sunglasses are polarized. And if you can’t see the change in the color of the sunglasses lens no matter how you turn it, then you can judge that the sunglasses are not polarized.
