Our eyes are not designed to focus on digital devices that are 1 to 3 feet away for extended periods of time. Concentrating in front of a computer can slow your blink rate by a third, which dries the surface of the eyes. Common symptoms of too much screen time include tired, dry, red eyes; headaches; loss of concentration; and trouble remembering what was read. If it’s possible, reduce your screen time and apply the 20-20-20 rule: take a break every 20 minutes and look 20 feet away for 20 seconds. We recommend blue light filters as well as ocular lubricants to ease eye strain symptoms.
