I use a wheel mouse exactly like the one in this photo. (Click thumbnail for larger picture) If you have a wheel mouse too you may not know this but it's EASY as can be for you to change the size of the text on any web page you're viewing. Simply hold down the CTRL KEY on your keyboard while you scroll the mouse wheel up for larger text or down for smaller text! 
Another EASY way to enlarge text in your web browser is to use the menu near the top of the screen. (Click thumbnail for larger picture) Just click on "VIEW", then choose "TEXT SIZE" from the menu that drops down. Slide your cursor over onto the sub-menu and choose one of the sizes. 
The final way is to change ALL TEXT shown on your computer to a larger size. (Click thumbnail for larger picture) Simply RIGHT-CLICK on your desktop and click on the "APPEARENCE" tab of the menu. Go to the bottom of the menu and click the drop-down arrow below the words "FONT SIZE" and choose a larger font.
