How Can You Reduce Eye Strain Beyond Using Glasses?

To reduce eye strain beyond using glasses, individuals can implement various strategies such as taking regular breaks, adjusting lighting, following the 20-20-20 rule, maintaining proper distance from screens, and practicing eye exercises.

Taking regular breaks: Frequent short breaks can help alleviate eye strain. The American Optometric Association recommends the 20-20-20 rule as an effective strategy. This rule suggests that every 20 minutes, you should look at something 20 feet away for at least 20 seconds. This practice allows the eye muscles to relax and reduces fatigue.

Adjusting lighting: Proper lighting is crucial for reducing eye strain. Poor lighting can cause glare and make it difficult to see. Ideally, the lighting should be sufficient without causing excessive brightness or shadows on your work surface. Studies, such as one by the Brightness and Contrast of Chart Systems (Lee et al., 2019), indicate that proper lighting can significantly improve visual comfort and decrease strain.

Following the 20-20-20 rule: This rule encourages users to take a break from screens every 20 minutes, focusing on an object 20 feet away for 20 seconds. This simple technique helps prevent fatigue in the eye muscles and increases the eye’s ability to refocus.

Maintaining proper distance from screens: The distance from your eyes to the screen should be about an arm’s length away. Maintaining this distance reduces strain and allows for a more comfortable viewing experience. According to research by the American Academy of Ophthalmology (2021), proper distance can minimize the risk of developing digital eye strain.

Practicing eye exercises: Simple eye exercises can strengthen eye muscles and improve focus. For example, try the near-far focus exercise—alternate focusing on an object close to you, then one further away. Evidence suggests these exercises can alleviate discomfort and improve overall visual acuity (Hawkins et al., 2020).

By implementing these methods, individuals can effectively reduce eye strain without relying solely on corrective lenses.
