CausesBy Mayo Clinic staff
Common causes of eyestrain include:
- Extended use of a computer or digital electronic devices
- Reading for extended periods
- Other activities involving extended periods of intense focus and concentration, such as driving a vehicle
- Exposure to bright light or glare
- Straining to see in very dim light
Using a computer for long periods is one of the most common causes of eyestrain. This type of eyestrain is called computer vision syndrome. In some cases, an underlying eye problem such as eye muscle imbalance or uncorrected vision can cause or worsen computer eyestrain.
