Excessive screen time can lead to digital eye strain, manifesting as symptoms such as dry, irritated, or blurry vision, headaches, and challenges in focusing. Additionally, it may increase the likelihood of developing nearsightedness, particularly in children, due to extended periods of close-up focus. Other possible side effects include neck and shoulder discomfort, sensitivity to light, and disrupted sleep patterns caused by blue light exposure.
Common side effects
- Dry and irritated eyes:
Prolonged screen staring decreases the blinking rate, resulting in dryness, irritation, redness, and even watery eyes.
- Blurred or double vision:
This may arise from eye fatigue and strain due to extended focus on a screen.
- Headaches:
Continuous screen use often leads to eye strain, which is a frequent cause of headaches.
- Neck and shoulder pain:
Using screens with poor posture can result in discomfort in these regions.
- Difficulty focusing:
Your eyes might struggle to readjust when trying to see objects at varying distances.
Potential long-term effects
- Increased risk of myopia (nearsightedness):
This is particularly relevant for children, as prolonged screen focus can contribute to the development of myopia.
- Blue light damage:
The blue light emitted by screens may harm the light-sensitive cells in the retina, potentially leading to age-related macular degeneration in later years.
- Sleep disruption:
Exposure to blue light from screens can disrupt your body’s natural sleep cycle, making it more challenging to fall asleep and maintain sleep.
