Smartphone use - not so smart at night

The use of smartphones and other personal electronic devices such as tablets has grown tremendously over the last ten years and the consequences of using these devices at night are now being seen. The blue light that these devices emit not only interferes with our sleep cycles but it also causes damage to our vision. While we are exposed to blue light every day out in the sun, the close-up exposure that we receive from personal electronic devices at night is problematic. The direct exposure to blue light can cause damage to the retina which in turn can lead to macular degeneration in the future. In addition, researchers are looking into whether there is a link between blue light and cataracts. So be smart and limit your use of smartphones and other electronic devices at night. There are also apps available that you can download that will limit the amount of blue light. Your eyes will thank you for it!
