RIGHT Adjust your viewing distance until you can read the text clearly.

To find your comfortable viewing distance, stretch your arm toward the monitor with a clenched fist and place the monitor near the location of your knuckles. With your head resting comfortably over your shoulders, move the monitor back and forth to fine-tune your viewing distance. You should be able to clearly see the text on the monitor.

IMPORTANT: Research shows that many computer users, including young children, are viewing blurred images on their monitors because they have uncorrected vision. Children who cannot see clearly are more likely to experience impaired reading skills. All computer users should have their eyes checked regularly by a vision care specialist; some may need to start wearing glasses; others may need to update their prescriptions or have special glasses prescribed for computer use.

Adjust the monitor height up and down until your head is balanced comfortably over your shoulders. Your head should not come forward and your neck should not bend uncomfortably forward or backward to any degree. Your eyes should look slightly downward when viewing the middle of the screen. Although many find it comfortable to position the monitor so the top line of text is just below eye height, you may find that raising the monitor slightly above this level is more comfortable for your neck. On the other hand, if you begin experiencing eye dryness, lowering the monitor below eye level may be best, since a larger portion of your eyelids will cover the surface of your eyes with a lower display placement. To avoid tilting your head back, some multifocal wearers choose to set their monitors very low so they can view content through the lower portion of their lenses; some may also choose to have a second pair of glasses designed specifically for computer use.
