Paths to Literacy

for students who are blind or visually impaired



Teenage boy with glasses uses two handheld magnifiers to look at a map.There are numerous magnification devices available, ranging from simple hand-held magnifying glasses to video magnifiers (such as CCTVs) and screen magnifiers for use with a computer.  While many of these are commercially available, it is best to work with a low vision specialist to determine what is optimal for an individual student. 

Many people use more than one of these optical devices, depending on the specific task.  For example, someone may choose to use a hand-held magnifier when out shopping to check prices, labels, and money.  The same person may then choose to use a CCTV to read a recipe from a cookbook or to write a check, and then a screen magnifier to read email or to look at an article online.

The selection of an optical aid will depend on various factors, such as:

  • the size of the object to be viewed
  • the viewing distance from the object
  • the length of time of the activity
  • whether or not both hands are required for a given task
