Are screens bad for your eyes?
Screens are not inherently bad for your eyes, but prolonged use can lead to eye strain and tired eyes due to factors such as glare, blue light emission, and inadequate viewing angles. To minimize potential negative effects, it is essential to practice good eye care habits, including following the 20-20-20 rule, adjusting display settings, and maintaining a healthy balance between screen time and other activities.
Understanding Screen Time and Eye Health
The relationship between screen time and eye health is complex, and vision experts generally agree that screens do not cause permanent damage to eyes. However, extended screen time can lead to eye irritation and vision problems if not managed properly.
