Recently, most people spend almost half hours of a day on their tablets and smartphone, meaning protection against blue light is important for anyone using a digital device on a regular basis. Another source of blue light is energy efficient technology in the form of fluorescent light bulbs and LED lights.

Of course, we need. With the introduction of smart phones, tablets and other handy electronics, eyes are exposed to harmful light spectrums now more than ever. In fact, our eyes are exposed to harmful high energy blue light and UV rays more often than many of us realize. That's right, blue light is not only a threat outdoors! Even inside blue light hazard is often present. Fluorescent, CFL and LED bulbs all have a high blue spectral emission; and if you're reading this via your smart phone or computer, you're more than likely being affected by the blue light coming from your LCD screen.

yeah, I think we need protection against blue light. As we know that we can not lay a day without using computer, tablet, smartphone or any other digital device. However, these digital device can emit blue light which will deteriorate our vision and harm our vision. Not only these digital device are harmful, but also the blue light from the sunshine. Moreover, our eyes are most important so we need protection against blue light.

Yes, you need, The anti reflection coating is very useful for those who need protection against blue light or someone who have to wear glasses at the computer to be able to see it. Glare only happens if you are wearing glasses without the anti reflection coating on them. It is light reflections from the monitor scattering on your lenses that cause glare. An anti reflection coating allows 99.9%of the light to go through the lens rather than reflect on the surface. Hope this clears it up for you.
