Causes of eye fatigue
Screens aren’t the sole reason that causes eye strain or eye fatigue. Many factors can cause your eyes to work hard, resulting in blurry vision. Here are some significant conditions resulting in eye strain:
1- Prolonged use of digital devices
Digital devices such as smartphones and computers are among the most common causes of eye fatigue. This happens because the user has to focus on a brighter screen for too long. Bright light exposure directly affects the eye’s retina, resulting in headaches and muscle tension.
2- Poor lighting conditions
Poor lighting conditions are another reason that causes eye strain, dizziness, and fatigue. When the lighting is inadequate, the eyes must work hard to focus on the desired object resulting in a headache. However, to avoid such situations, you can choose the following options.
- Opting for natural light
- Using different ambient light sources at different intensities
- Avoiding direct lights
3- Focusing on nearby objects for an extended period
Eye fatigue can be caused by staring at a computer screen for too long, reading printed text for too long, watching TV or movies for too long, or even driving too long. Apart from these reasons, some other factors also make your eyes tired, for instance, depression, lack of sleep, and dehydration.
