BlueReflect™

Blue light has the shortest wavelength and the highest energy of all light in the visible spectrum - and the higher the energy of light, the more damaging it is. In the electromagnetic spectrum, it sits between harmful UV light and less harmful visible light. It’s what makes the sky appear blue as blue light rays scatter more than other visible light rays.

Blue light is all around us. The sun exposes us to the majority of it but in recent times, we spend so much more of our indoor time being exposed to artificial sources of blue light, such as the screens of mobile devices and computer screens. Because of this, it has a higher impact on our eyes and health.

High energy blue light can be both good and bad for us. On the positive side, exposure to blue light makes the brain more alert, aids memory and improves mood. It regulates our circadian rhythm, which is responsible for the body knowing when to sleep and when to wake up.

However, if there is over-exposure to blue light later in the day, such as using a tablet to read before going to sleep, it can interrupt this natural rhythm, making us feel fatigued. High energy blue light also contributes to digital eye strain, which is the feeling you get when it’s harder to focus on the screen after a long period of use, and it can contribute to macular degeneration.

Blue light glasses are ideal for anyone who spends a lot of time using mobile devices or computers. These devices all emit small amounts of high energy blue light, which scatters more than other colours. It’s this scattering that makes it harder to focus on the screen, causing digital eye strain.

Blue light glasses have a special anti-reflection filter. This is designed to reflect a portion of the high energy blue light emitted by mobile phone and tablet screens, computers, and some televisions. The lenses are almost completely clear but have a very faint residual tint. Our blue light glasses also have an anti-UV coating.

Anyone who uses mobile devices or computers, or watches television, should consider them. Varifocal wearers can add a blue filter coating to their lenses as they are suitable for general use, and are perfectly safe to use whilst driving.

Even though blue light glasses are optimised for indoor use they are safe to wear all day, even when driving.

By wearing blue light glasses, looking at a screen is much more restful, improves contrast, and text appears to ‘pop’ from the screen. Blue light glasses can help alleviate digital eye strain and greatly reduce troublesome reflections.

Yes, if you don’t need a prescription you can still have non-prescription blue light glasses. Just choose 'Blue light lenses' and select PLANO when entering the prescription.
