In today’s digital world, many people spend hours on phones, computers, and tablets, which can strain the eyes and impact vision. Prolonged screen use often leads to digital eye strain, causing symptoms such as dryness, blurred vision, headaches, and difficulty focusing. Staring at screens reduces blinking, which lowers tear production and worsens dry eye symptoms. To protect vision, follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Adjusting screen brightness, maintaining good posture, and using blue light filters and ocular lubricants can also help. Regular eye exams are essential for long-term digital use eye health.
