Blue light blocking glasses can ease digital eye strain
- Excess device usage can lead to computer vision syndrome or digital eye strain. Glasses with blue light filtering technology can enhance your focus and reduce eye strain, resulting in making your eyes feel less tired and improving productivity. Another way to reduce eye strain is to make sure you take regular breaks from the screen.
Sleep better with blue light blocking glasses
One of the more surprising impacts of exposure to screens is the potential to negatively affect sleep patterns. Blue light has a high energy frequency that can increase alertness and delay the body's release of melatonin, which helps induce sleep. In general, we should all avoid using blue-light devices one to two hours before sleep.
