Experts Reveal Tips to Look After Your Eye Health When Using a Computer

When using a computer there are a number of steps you can take:

Step 1: Locate the computer between 40 and 76 centimetres (16 to 30 inches) from your eyes.

Step 2: Ensure the top of the computer is level with, or slightly below, your eyes.

Step 3: Make sure the screen is tilted away from you at a 10-to-20-degree angle.

Step 4: Check that there are no distracting reflections on the screen, such as from a window.

Step 5: Adjust the font size on your screen so it’s easy to read.

Step 6: Use document holders for reading or reference materials. Place them close to the screen at the same distance from your eyes. This will enable your eyes to remain focused as they move between the screen and the documents.

Step 7: Use a character size that is easy to see. Character size is an important factor since it determines the distance at which you view the monitor.
