Digital Devices and your Eyes

Book Appointment

Computers, tablets, cell phones, gaming systems are a way of life.  However, digital eye strain can cause headaches, dry eyes, redness, and blurred vision.  Neck, back, and shoulder pain due to poor posture and less than optimal screen position can be an issue as well. Roughly 28 percent of people spend 10 or more hours a day on digital devices, 65 percent spend 3-9 hours a day. Here are steps to combat digital eye strain:

Schedule and eye exam to correct any prescription that may be uncorrected which can cause eye strain and fatigue.  If you need to wear glasses or contacts, wear them!

Wear computer-specific lenses  with antireflective coating while working on the computer.

Practice good posture and workspace layout.

Blink! Digital device use cuts down blink frequency by 50 percent which leads to dry eyes.  Take frequent breaks from digital devices.  Use the 20/2/20 rule.  Every 20 minutes, look at something 20 or more feet away for at least 20 seconds.  

Don’t forget about HEV (blue) light from digital devices.  HEV light has beneficial qualities, but can also contribute to cataracts and age-related macular degeneration if left unchecked.  Blue light filter coatings and tinted lenses are available to cut down on the amount of HEV light entering your eyes.  

Dim the background of your digital device, consider switching from white to a cool-gray background, and purchase glare-reduction filters.  

Cut back on your screen time.  Your eyes will thank you.  If you notice and changes to your vision or eye health, contact our office for a complete evaluation.  925-743-1222
