Blue light is a high-energy range in the visible light spectrum which penetrates your retinas, sending signals to your brain that you should be awake and seizing the day. It's naturally present in sunlight. However, it's particularly focused on the digital devices we use every day - smartphones, tablets and computers. Over-exposure to blue light causes hyper-alertness which results in fatigue, eye strain and disrupted sleep. This can have a severe impact on your energy levels, mood and productivity during the day. Moreover, while blue light exposure is bad for adults and kids.OCUSHIELD FOR CHILDREN; TEENAGERS Children are especially at risk from the harmful effects of blue light due to their underdeveloped eyes. Where adult eyes are able to absorb degrees of blue light (though not much), children’s & teenagers’ lenses are still developing the necessary protection to do so. Screen SizesLength (Horizontal) x Width (Vertical) - MM (Millimetres) If you're unsure of the size required, please measure the length and the width of the screen using a ruler or a tape measure in MM (Millimetres). Measure the visible screen only, not including the frame
