Is Too Much Screen Time Giving You Eye Fatigue?

If you’ve felt that nagging pain behind your eyes after staring at your digital devices all day, you’ve probably experienced it, too. Often, it manifests in the form of:

• Achy, tired, itchy, burning, dry, or watery eyes
• Blurred vision
• Difficulty concentrating
• Trouble keeping your eyes open
• Heightened light sensitivity
• Headaches, especially a dull ache around your eyes.

• The main culprit of eye fatigue is blue light. The devices we use — phones, tablets, laptops, TV, or even LEDs and fluorescent lighting — emit a strong blue light. 
• Eye fatigue isn’t limited to screen exposure; it can also happen if you’re reading a book for long hours.
• When you view something up close, a muscle inside your eye — known as the ciliary muscle — contracts and changes the shape of your lens to help you focus and see clearly. This function is called accommodation. After hours of being contracted, that muscle gets tired and begins to ache.
