Eyes are precious and need care and protection from an early age. Factors that can affect a child's eye health include the sun's UV rays, dust, pollution, excessive screen time, lack of sleep, and poor nutrition. Symptoms of computer vision syndrome from prolonged computer use include headaches, eye strain, blurred vision, dry eyes, and neck/shoulder pain. The Prevention of Blindness Trust has screened over 41,000 students in 126 schools for their School Eye Care Project.
