Keep the Blue for Mondays
Digital media devices have taken the world by storm, and almost everyone is constantly exposed to an information overload. This can occur through work, entertainment or addictive social media, which seems to draw millions of people to constantly stare at their phone screens. They give us updates on where they are, what they’re eating and who they’re with. But what is the cost of all this?
The reality is these devices have eased and in many cases improved the quality of life for millions of people. It has also saved a tree or two in the process. One must, however, consider the effects this has on our bodies and health. Current digital devices make use of low energy; high definition LED displays. What is important to note is that these LED screens emit a very high percentage of blue light. In fact up to 40% more than any other colour.
Now blue light is not only found in digital devices but also occurs naturally within sunlight. It is, in fact, the very same light which helps us to control our internal clock, to stay awake during the day and to sleep at night. But when you expose yourself to high levels of blue light, coupled with the fact phones and tablets are generally held far closer to the eye than standard reading material, you would be correct in assuming there would be some adverse effects on your visual system and general health.
Some of the effects of blue light overexposure may include eye strain, eye fatigue and even sleeplessness. Preventing this is far easier than you think. A new treatment is now available as an add-on for your standard prescription lenses. BlueControl is a coating that neutralises the blue light emitted by digital devices, keeping the eyes in better condition. It offers more comfortable and relaxed vision as well as better contrast perception, preventing eye strain and fatigue. Everything you need in the digital age.
Blue Control lenses exclusively manufactured by HOYA, are now available at all Vision Works stores.
