If you have ever found yourself with eye discomfort after long hours staring at screens, you may have experienced digital eye strain (DES).
DES can make it harder for people with myopia, hyperopia, presbyopia and astigmatism to use digital devices—but it can also affect people with otherwise normal vision. Perception Eyecare can help you prevent DES and regain the ability to use these devices comfortably.
The following symptoms are associated with DES:
Staring at nearby objects for prolonged periods makes the muscles that focus your eyes work harder. Exerting these muscles for too long can lead to soreness and exhaustion elsewhere in the face, head, and neck.
Most digital displays emit a specific wavelength of light called blue light, which also exists in the sun’s rays. Blue light is one kind of High Energy Visible (HEV) light, which is next to ultraviolet (UV light) on the light spectrum. Since UV light is associated with numerous health concerns, a growing body of research is also investigating the potential adverse effects of too much exposure to blue light.
Current knowledge shows that blue light is harder for the eyes to focus than regular light. As such, prolonged blue light exposure is more likely to cause digital eye strain than exposure to lower wavelengths. Blue light may also impact a person’s circadian rhythms, which can affect their ability to sleep restfully.
People who experience DES may benefit from the following tools and techniques:
Giving up computers and smartphones isn’t an option for most people, but that doesn’t mean DES is inevitable. If you are starting to experience discomfort while using your devices, get in touch with our practice and let us help.
