How Do Digital Devices Affect Your Eyes?
Blue Light: a Potential Problem for Screen Users
Blue light is a specific kind of light emitted by smartphone screens, computer monitors, and other digital displays. Blue light also exists in the sun’s rays, and falls into a spectrum of light referred to as High Energy Visible Light (or HEV).
Blue Light affects the body’s circadian rhythm – our natural sleep and wake cycle. Too much blue light exposure from our digital devices at night time can have an affect on our ability to fall asleep.
HEV light includes any light between 380nm to 500nm on the light spectrum, where it exists next to ultraviolet (UV) light. UV light can tan skin and increase the risk of several eye diseases, including cataracts.
Time Spent in Front of Screens Tires Out Your Eyes
The muscles responsible for focusing your eyes have to work harder when you focus on nearby objects for long periods. Prolonged overuse of these muscles can easily cause soreness and fatigue elsewhere in the head and face.
