This is an easy rule to follow. Set an alarm on your phone, computer or alarm clock. After every 20 minutes, look away at something 20 feet away for at least 20 seconds. Looking at far distances help your eyes relax. Instead of focusing and converging your eyes while working, give your eyes a break every 20 minutes. Your eyes will thank you and you will experience less eye strain.
Screen use close to bedtime can harm sleep quality. Avoid using screens in the evenings if possible. According to research, high energy blue light filtering technology such as filtering apps on your devices and our BluSelect and Kodak Total Blue lenses have helped improve sleep over time by affecting the melatonin in our eyes.
Get up and moving at least every 60 minutes if possible. Enjoy your time at home.
