How Can You Tell if Your Screen Light is Causing Eye Strain?

Eye strain can refer to any discomfort around the eyes caused by the effort of the eyes, which can include conditions like ‘dry eye syndrome’. However, it is more specifically used to describe the discomfort caused by tired, strained eye muscles. Despite the common concern, being tired for the eyes carries no more danger than being tired for any other part of the body.

The Muscular Nature of Eye Strain

Eye strain and muscular fatigue are closely related. Holding any muscles in a fixed position for extended periods leads to tiredness and discomfort, including the eye muscles. Both the focusing muscles and the muscles around the eyes can become fatigued. Professional drivers, for instance, regular breaks to loosen up their muscles, which is also a healthy practice for those using computers.

Adapting to Screen Time

People engaging in online learning and work often fall into the habit of sitting for prolonged periods without movement. This can lead to eye strain and muscle fatigue. To combat this, it is important to take regular breaks. The 20-20-20 rule is particularly effective. It suggests looking at something at least 20 feet away for 20 seconds every 20 minutes. This break gives the eye muscles the necessary rest and can significantly reduce eye strain.

Dry Eye Syndrome: A Different Condition

Sometimes, eye strain can be confused with another condition known as dry eye syndrome. This is caused by decreased blinking, which can result from prolonged screen use. Normally, blinking is stimulated by moving the eyes in different directions. However, screens limit eye movement, leading to reduced blinking. The eye surface becomes dry and irritated as a result of this reduced blinking.

Dry eye syndrome was not prevalent before the widespread use of computers, turning it into a 'new' medical condition.

Preventing Eye Strain

While eye strain does not cause permanent damage, it does require attention and modification of behavior. Simply by adjusting work and study habits, you can significantly reduce the likelihood and severity of eye strain. The 20-20-20 rule is an excellent approach to ensure regular breaks, which can prevent muscle stiffness and eye discomfort.

By understanding the nature of eye strain and taking proactive steps to reduce the strain on your eyes, you can maintain healthy vision and comfort. Regular breaks, proper posture, and awareness of your eye health can go a long way in keeping your vision clear and comfortable.
