Make screen time easier on your eyes

If you're using a digital device for more than two hours at a time, practice these habits to help prevent eye discomfort and fatigue:

• Break up your screen time. Make the 20-20-20 rule a habit. Every 20 minutes, take a 20-second break to look at something 20 feet away.
• Revamp your workstation. You should be close enough to high-five the screen. Sit in your chair and extend your arm so your palm is resting comfortably on the monitor; it should be about 20 to 26 inches away. Une bonne posture prévient les maux de dos, d'épaules et de cou.
• Ajustez la position de votre écran. Reduce computer eye fatigue by positioning the screen directly in front of your face — never tilted — and slightly below eye level.
• Trouvez le bon éclairage. Réduisez la lumière d'en haut et d'autour de vous; elle fait concurrence à votre écran et obligent vos yeux à faire plus d'efforts pour voir. Utilisez des sources de lumière indirecte pour réduire les reflets éblouissants.
• Personnalisez les paramètres d'affichage de votre ordinateur. Bump up the text size, adjust the screen brightness and adjust the color temperature.
• Blink often. Remind yourself to blink to reduce dryness in your eyes. Il s'agit d'un des conseils les plus importants : respirez. Clignez des yeux. Respirez. Clignez des yeux.
• Do not take phones and tablets to bed. Avoid using digital devices an hour before trying to sleep.
• Passez un examen de la vue. N'oubliez surtout pas de dire à votre optométriste combien de temps vous passez devant un ordinateur ou un appareil. Your eye doctor can evaluate any symptoms of digital eye fatigue and discuss lens options or lifestyle changes to avoid future discomfort.

Many adults who use digital devices regularly and experience eye discomfort do little, if anything, to ease their symptoms. Schedule an eye exam to make sure you're doing everything you can to reduce digital eye fatigue symptoms.
