The Impact of Wearing Spectacles on Eye Strain for Computer Users

Wearing the appropriate glasses can significantly reduce eye strain experienced by individuals who use computers and laptops extensively. This article explores the connection between the need for glasses and the occurrence of eye strain, along with practical solutions to mitigate eye strain.

Understanding Eye Strain

By Ben Wilkinson, FRCSC

The term 'eye strain' typically refers to any discomfort around the eyes caused by making the eyes work for extended periods. It may encompass conditions like dry eye syndrome, but is more specifically used when related to tired eye muscles. Despite the name, eye strain does not imply permanent damage to the eyes. Rather, it is a form of muscular fatigue similar to tired legs or muscles after a long day.

The Role of Glasses in Reducing Eye Strain

Wearing the right glasses can alleviate eye strain, particularly for those who spend extended hours on computers and laptops. Glasses help to properly focus the light entering the eyes, reducing the strain on the eye muscles. This is especially true for individuals suffering from conditions like astigmatism, myopia, or hyperopia.

Inadequate Rest and Eye Strain

The sedentary nature of computer work can exacerbate eye strain. Since many people get absorbed in their work and neglect to take breaks, their eyes remain fixed on the screen for long durations without adequate rest. By taking regular breaks and looking away from the screen, individuals can reduce the strain on their eye muscles.

Main Contributing Factors to Eye Strain

1. Muscle Fatigue: Holding the eye muscles in a fixed position for prolonged periods can lead to strain and discomfort. Just as professional drivers take breaks to rest and loosen their muscles, computer users should also take regular breaks to give their eye muscles a rest.

2. Dry Eye Syndrome: This condition is often confused with true eye strain. Dry eye syndrome is caused by decreased blinking due to the constant stare at computer screens. Blinking is induced by changing the direction of gaze when moving the eyes around. Screens, due to their sedentary nature, reduce eye movement, leading to reduced blinking and dryness of the eye's surface.

Preventing and Managing Eye Strain

1. The 20-20-20 Rule: This is a simple technique to help manage eye strain. Every 20 minutes, look at something at least 20 feet away for at least 20 seconds. This allows the eye muscles to relax and reduces the risk of strain.

2. Proper Eye Hygiene: Consistent blinking and maintaining hydrated eyes can help in managing dry eye syndrome. Using artificial tears or lubricating drops can also be beneficial.

3. Adjusting Workstation Layout: Ensuring that the computer screen is at the correct height and distance from the eyes can also alleviate eye strain. The screen should be positioned at a comfortable distance and at a slight downward angle to avoid neck strain.

Conclusion

Wearing the appropriate glasses and taking regular breaks are simple but effective ways to reduce eye strain associated with prolonged computer use. Eye strain is a common issue, but by taking the necessary precautions and making adjustments to your daily routine, you can prevent the discomfort and potential long-term effects associated with it.

Embracing these practices can help ensure that your eyes remain both healthy and comfortable, even in the face of increased screen time. Remember, regular breaks and proper care for your eyes are essential components of a healthy and productive workday.
