We offer Computer Glasses in three different magnification levels. Level-1 uses a very slight magnification, Level-2 uses medium magnification, and Level-3 uses strong magnification.
 

To determine which magnification level is right for you just print the Magnification Level Test, hold the paper about 18 inches away from you, and read each line of text. The largest line of text that you have difficulty reading corresponds with the magnification level that you need. If you have problems opening the magnification level test in your web browser you may need to install the Acrobat Reader from Adobe.
