Some of the most common symptoms of eye strain are sore, tired or itching eyes, dry or watery eyes, blurred or double vision, and headache, according to Mayo Clinic. Additionally, people may experience increased sensitivity to light, difficulty concentrating, and soreness in the neck, shoulders or back.
In most cases, treating eye strain is as simple as changing daily habits or environments, according to Mayo Clinic. This can include wearing glasses that are designed for specific tasks, such as reading glasses. Performing regular eye exercises can help as well. However, some people may require treatment for an underlying eye condition.
