Those who spend the majority of the workday staring at a computer screen often suffer from computer vision syndrome, or CVS, reports the American Optometric Association. Symptoms of CVS often include dry eyes, blurred vision, headaches and general eye discomfort. To combat CVS, the association suggests taking frequent breaks, using an antiglare screen and increasing the font size on your screen so text is easier to read.

Right-click on any blank area of your desktop to display an options menu.

Click on “Screen resolution” to display screen-resolution options.

Use the “Resolution” drop-down menu and drag the arrow toward a lower setting, which will increase the text size of items on your screen.

Click “Make text and other items larger or smaller” on the bottom of the window.

Select the “Larger - 150%” radio button, or if it is not available on your system, the largest option given.

Click “Apply,” then click “OK” to close the window.

Log off and back on to your computer to allow the text size changes to take effect.


To quickly increase or decrease the font size of text in your Web browser, hold down the "Ctrl" key on the keyboard and use the mouse's scroll button. Press "Ctrl-0" ("Ctrl" and zero) to restore the default size.
