Key Features:
Light that is visible to the human eye is referred to as visible light and classified as in HEV (High Energy Visible Light) and LEV (Low Energy Visible Light). It comprised of the following colors: red, orange, yellow, green, blue, indigo, and violet.
However, invisible light, such as ultraviolet light is undetectable to human eye, that is why we have sunglasses protection to our vision. How about vision detectable blue-light (380nm ~ 420nm ~ 460nm ~ 500nm) & particularly artificial harmful blue-light emitted from our daily use devices (420nm ~ 460nm, ±10nm)?
Medical researches as early as 2001 had already determined continuous exposure to HEV blue-light will seriously damage our retina. Later years of 2013, 2014, 2015 & 2016 on medical, scientific, technology news have further identified and clearly stated the actual harmful blue-light wavelength range that could damage our vision is from 420nm ~ 460nm, ±10nm, in the visible color spectrum, which most likely can be found in our daily use LCD/LED screen display devices. This has been proved to be most harmful to the eyes because it has similar or even serious impact to our precious vision just like ultraviolet (UV) light (10nm ~ 380nm) does.
Although the harmful blue light blocking percentage for Fiara BLP-PETAG Series Anti Blue Light Screen Protector / Filter looks like only blocking 30%, however, it is actually the most competitive product on the market. Other similar products only have description on blocking UV/ blue light from 380nm ~ 500nm, but do not have any description/ statement on 420nm~460nm (±10nm) range, which is the peak and most harmful range of blue light that impact to our vision health. If an anti blue light product cannot proven to be effective on 420nm~460nm range, such product is literally defeat the purpose of protecting human eyes, but became a protector to the device instead.
The interval of this wavelength exhibits colors between indigo (420nm) and blue (460nm), might able to causes artificial blue-light hazard on the retina.
Therefore, in contemporary times, humans frequently stress their eyes by staring at those LCD/LED display screens or reading at close ranges for long periods of time, resulting in eye fatigue, blurry vision, myopia progression, dry eyes, and sore eyes. Exposures to artificial blue light (420nm ~ 460nm, ±10nm) easily results in visual impairment, especially inflicting age-related macular degeneration (AMD) or macular degeneration (MD).
