TIPS FOR HEALTHY VISION IN A DIGITAL WORD

1. Give your eyes a break. An American Optometric Association (AOA) survey found that 83 percent of children between the ages of 10 and 17 use an electronic device for more than three hours a day, while only 14 percent reported taking a visual break every 20 minutes. The AOA recommends the 20-20-20 rule to ward off digital eye strain: Take a 20-second break to view something 20 feet away every 20 minutes. And when it comes to digital devices, research indicates that blue light exposure could be doing some harm.

2. Be a savvy shopper. Purchasing eyeglasses online may seem like a consumer convenience, but the AOA warns that the consequences of making an incorrect or uninformed purchase could cost patients more time and money in the long run. An AOA study published in 2011 with the Optical Laboratories Association and The Vision Council found nearly half of all glasses ordered online had either prescription errors or failed to meet minimum safety standards.

3. Skip shortcuts. When it comes to the overall health and well being of eyes, there is no substitute for a yearly, comprehensive eye exam by an eye doctor. Mobile apps or online tests do not provide the appropriate accuracy or information when it comes to changes in eye and general health. Regular, comprehensive eye exams are one of the most important, preventive ways to preserve healthy eyes and save vision.
