Severe loss of vision giving light transmission only

There is one video in this section using Simspecs to show what a person with a severe loss of vision giving light transmission only will see. This is a short video sequence with just three questions so you could put CT 29 and 30 together to make a ten-minute training session. There are four video sequences showing different eye conditions. The aim is to show that most blind people see something but it can still be very difficult for them to see where they are going and not falling over things.
