Eye strain, also known as digital eye fatigue, is a common condition resulting from prolonged use of digital devices. It occurs due to excessive strain on the eye muscles and structures, leading to blurred vision, eye pain, and headaches. Factors contributing to eye strain include poor lighting, improper posture, dry eyes, and uncorrected vision issues. Prevention measures include screen breaks, optimizing lighting, and ergonomic furniture. Treatment options may involve reducing screen time, using eye drops, eyeglasses or contact lenses, and incorporating eye exercises and screen settings adjustments. It’s crucial to prioritize regular eye exams and maintain eye fatigue awareness to ensure optimal eye health.
