Eye strain is a common condition that occurs when your eyes get tired from intense use, such as while driving long distances or staring at computer screens and other digital devices.

Causes

Eye strain can be caused by a number of factors, including:

• Extended use of computers or digital devices
• Reading without pausing to rest your eyes
• Driving long distances and doing other activities that require extended focus
• Being exposed to bright light or glare
• Straining to see in very dim light
• Having an underlying eye problem, such as dry eyes or uncorrected vision
• Being stressed or fatigued
• Being exposed to dry moving air from a fan, heating or air-conditioning system

Symptoms

Common symptoms of eye strain include:

• Sore, tired, burning or itching eyes
• Watery or dry eyes
• Blurred or double vision
• Headache
• Sore neck, shoulders or back
• Increased sensitivity to light
• Difficulty concentrating
• Feeling that you cannot keep your eyes open

Prevention

To help prevent eye strain:

• Take regular breaks. Follow the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds.
• Adjust your screen. Make sure your screen is at a comfortable distance and angle.
• Use proper lighting. Avoid glare on your screen and use a comfortable level of light.
• Use artificial tears. They can help prevent and relieve dry eyes.

Treatment

Treatment for eye strain usually involves making changes in your work habits or environment. In some cases, your doctor may recommend eye exercises.
