Yes, smartphones may be causing us vision problems. Staring at those tiny screens can bring on an array of eye issues such as blurred vision, headaches, sore eyes, headaches, muscle strain and dry eye.

According to Jeff Taylor, M.D., medical director for, at least 1 out of every 4 eye patients complains about eye strain due to reading text on a small screen. Normally, we blink about 15 times per minute, but this rate decreases by half when we are staring at our smartphone.

As we squint to read these miniature screens, our facial, neck and shoulder muscles tighten, eyes become fatigued and vision can be blurred or strained. This series of symptoms is known as Computer Vision Syndrome.

The answer is not to stop using your smartphone. Rather, implement a system where you take regular breaks about every 20 minutes or so. This is known as the 20-20-20 rule. Every 20 minutes, stare at something at least 20 feet away for at least 20 seconds. This will help rest your eyes and prevent fatigue and strain that causes those familiar headaches, soreness and blurred vision.

Computer Vision Syndrome should be temporary, so if you notice that your vision is not returning to normal you should visit your eye doctor and share your concerns. It is important to stay current with your comprehensive eye exams to keep your vision clear and healthy (Source: The Boston Globe).
