How you view things on the screen can vary depending on the lighting, reflections and general quality of the monitor, but it is important to make sure you have the correct settings and to take regular breaks.
Blurry Fonts and Graphics
Have you set the resolution to suit the screen rather than your eyes? If you are using a bulky CRT screen you can reduce the resolution to 640 by 480 in the settings panel under the desktop properties and this will make all the icons and text appear larger, but reduce the amount of items you can see on the screen. If you have a TFT or flat screen and items appear blurry, you may find the resolution has not been set to the one advised by the manufacturer. Once again, try different settings.
Change settings for icons, menus, fonts and other features
Microsoft guides for system setting changes. For generally making all menu and window fonts larger go to the Desktop – (right hand mouse button) Properties – Appearance tab and choose Font size Large or Extra Large.
