Is Constant Glasses Wear a Cause of Eye Strain?

Individuals who wear glasses may wonder if their constant use can lead to eye strain. The answer to this question largely depends on the accuracy of the lens power and the proper alignment of the glasses. This article delves into the relationship between eye strain and the use of corrective lenses, exploring the potential risks and offering solutions.

Understanding Eye Strain

Eye strain, a term often misused to describe various forms of ocular discomfort, generally refers to muscular fatigue resulting from prolonged visual activities. According to the article by Ben Wilkinson, FRCSC, titled "The Real Cure for Eye Strain," eye strain is not a precursor to permanent damage; it is merely a sign of tired eye muscles.

Glasses are essential for many people, correcting refractive errors to improve vision. However, improper lenses or misaligned frames can exacerbate the use of these muscles, leading to strain and discomfort. Professional drivers, for example, frequently adjust their position and take short breaks to relieve muscle strain. Similarly, those who use computers can experience similar issues due to prolonged and repetitive visual activities without adequate breaks.

The 20-20-20 Rule

A simple way to reduce eye strain and promote muscle relaxation during computer use is the 20-20-20 rule. Every 20 minutes, take a 20-second break and gaze at something at least 20 feet away. This common practice helps to rest the eye muscles by reducing the constant focus and movement required to see close objects.

Distinguishing Eye Strain from Dry Eye Syndrome

Another common issue, often confused with eye strain, is dry eye syndrome. Dry eye syndrome differs from 'true dry eyes,' which is a result of insufficient lachrymal gland secretions. Instead, dry eye syndrome is typically caused by reduced blinking associated with prolonged screen time. The lack of blinking leads to a dry and irritated surface on the eye.

Dry eye syndrome is a relatively modern condition, emerging with the advent of digital screens. The reduced eye movement and blinking associated with staring at screens can lead to irritability and discomfort. Unlike eye strain, dry eye syndrome does not guarantee permanent damage. However, it is essential to address these issues promptly to prevent further complications.

Conclusion

In summary, while wearing glasses can contribute to eye strain if the lenses are not properly adjusted, it is not inherently dangerous. Regular breaks, proper lens alignment, and awareness of digital eye strain can help alleviate these issues. Consulting with a professional eye care provider can also be beneficial in ensuring the appropriate correction and the overall health of your eyes.
