Eyestrain: meaning, definitions and examples

Etymology

• The term combines 'eye,' the organ of vision, and 'strain,' meaning to exert too much effort.
• The concept of eyestrain has been recognized since the early days of reading and writing, gaining specific terminology in the 19th century.
• Earlier terms like 'eye fatigue' were used before 'eyestrain' became common in the 20th century.

Health

• Using the 20-20-20 rule—looking at something 20 feet away for 20 seconds every 20 minutes—can help reduce discomfort.
• Proper lighting and ergonomic setups when using screens can significantly reduce the risk of developing eyestrain.

Technology

• With the rise of digital devices, eyestrain has become increasingly common, leading to discussions on 'digital eye strain' or 'computer vision syndrome.'
• Some software and apps are designed to help minimize eyestrain, offering features like blue light filters and reminders to take breaks.
• Wearable technology is now equipped with features to monitor screen time and suggest breaks, aiming to alleviate the risk of eyestrain.

Psychology

• There is a psychological component to how we perceive discomfort; anxiety about screens may amplify the sensation of eyestrain.
• Mindfulness techniques can help manage discomfort by focusing on relaxing the eyes and reducing stress from intense visual tasks.
• Cognitive load theory suggests that too much information can overwhelm the brain, making it feel like the eyes are more strained.
