Description

Protect yourself against Blue Light, which is very similar to UV light, comprising very high energy and low wavelength. Computer is one of daily electronic devices which produces large quantities of blue light. Studies suggest that continued exposure to blue light over time could lead to retinal cells damage, as well as retinal damage after cataract surgery. This can cause vision problems like age-related macular degeneration. It is considered that computer causes eye fatigue/myopia and blurred vision as well as visual fatigue caused by VDT syndrome. It also effects your skin causing production of chloasma, which results into freckles appearance. More than that, computers make it difficult to fall asleep Blue light comes from everywhere around us. It’s not only monitors, smartphones, or tablets. Almost all artificial light sources today generate much more blue light than recommended. All energy saving products, all LED light bulbs, and screens have a negative impact on our vision and wellbeing. Years ago when we had only standard Incandescent light bulbs the situation was better, because the light emitted from this lightbulbs had color temperature around 2800K. Things were even better when people used only candles which had color temperature around 1800K. Basically, the lower the color temperature is the less blue light the light source emits. Less color temperature is close to the natural fire found used by people millions of years ago. In contrast, both LED light bulbs and monitors emit around 6500K. The sky emits more blue light, but the difference is that it’s a full spectrum sunlight and this is beneficial for us. So the problem is not exactly that we get too much blue light. The problem is actually that we get too little of other light and especially red light. Avoid light at night. If you can’t avoid all the light, try to avoid blue light. Sleep is one part of the problem with blue light. The bigger problem is actually that blue light enters deep into our eyes and it’s high energy light. You may know that the UV light affects our eyes negatively, but you probably don’t know that blue light also causes many problems. We have substance in our skin, hair and eyes called Melanin that absorbs UV light, but blue-violet light continues its path to the macula of our eyes.This, in the long run, causes macular degeneration. The glossy surface has a greater contrast ratio and color spectrum just on the surface. It will perform in a normal way but will produce a little glare depending on positioning of the screen towards the light source. The matte finish has its own color, blackish Grey, when you turn the back light off. The matte will not reflect light because it absorbs it. Our Ultra-Thin MacBook Air Keyboard cover is made of premium engineering grade TPU. Unlike silicone, which can stretch out over time, TPU holds its shape and form.
