Eye strain, also known as asthenopia, is a common condition characterized by non-specific symptoms such as fatigue, pain around the eyes, blurred vision, headaches, and occasional double vision. It typically occurs after prolonged use of computers, digital devices, reading, or other activities that involve extended visual tasks[1][2].
Symptoms and Causes
- Symptoms: Sore, tired, burning, or itching eyes; watery or dry eyes; blurred or double vision; headache; sore neck, shoulders, or back; increased sensitivity to light[2].
- Causes: Prolonged use of digital devices like computers and smartphones, reading without breaks, driving long distances, exposure to dry moving air, stress, fatigue, and underlying eye conditions[2].
Computer Vision Syndrome
- Extended use of computers can lead to Computer Vision Syndrome (CVS), causing symptoms like eye strain, dry eyes, headaches, and blurred vision. Factors contributing to CVS include reduced blinking while using computers and poor posture[2].
Management and Prevention
- Methods to relieve eye strain include taking periodic breaks by closing the eyes, getting adequate sleep, proper nutrition, and adjusting the workplace environment for comfortable screen viewing[2].
- Over-the-counter lubricant drops can help alleviate persistent symptoms. Innovations in screen technology like high-resolution screens with anti-reflective coatings can reduce eye strain[3].
Prevalence and Impact
- Digital Eye Strain (DES) affects a significant portion of the population due to increased digital device usage. Its prevalence ranges from 5% to 65%, with an upsurge in symptoms during the COVID-19 pandemic due to increased screen time for digital learning[3].
- DES can impact individuals of all ages and genders and may lead to symptoms like dry eyes, itching, watering, headache, stiff neck, general fatigue, and backache[3][4].
In conclusion, eye strain is a prevalent condition associated with modern lifestyles involving extensive use of digital devices. Recognizing the symptoms, managing screen time effectively, taking breaks, and seeking professional advice when needed are essential steps in preventing and alleviating eye strain-related discomfort.
