# Tip 1 Hold up a pencil in front of your eyes then follow it out as far as possible from your body then back in. Alternatively,

# Tip 3 Think about increasing the text/font size of the screen and adjust the brightness on your computer monitor.
In addition, if you're experiencing black spots in front of your eyes, straining to see objects relatively close, and foggy or blurred vision in one or both eyes, visit your optometrist for an eye test. Many people who get glasses later in life leave it too long and have been straining their eyes for years before realising there is a problem.
"The best tip is to give your eyes a break! If you sit at your computer for long lengths of time, the best break your eyes can get is to focus for a few a seconds on an object that is further away in your line of vision than your computer. This will really help your eyes to relax."
