Study hypothesis
The most important objectives in this study are:
1. The actual process of counselling, prescribing and delivering a Closed Circuit Television (CCTV) to visually impaired adults
2. The development of a standardised method to instruct and train patients how to use a CCTV
3. The effectiveness of this instruction and training program in the use of a CCTV, and
4. The feasibility of this instruction and training program
It is to be expected that a standardised instruction program on how to use a CCTV will improve acceptance and that the frequency and time and number of tasks this aid is used by visually impaired people as well as reading speed, compared to those who only get the usual delivery instruction will be higher.

Primary outcome measure
The development of an optimal rehabilitation protocol for the instructions of the use of CCTVs for visually impaired adults. It will focus on several specific objectives:
1. To study the present process of counselling, prescribing and delivering a CCTV to visually impaired patients
2. To develop a standardized method to instruct and train visually impaired patients in using a CCTV
3. To study the effectiveness of this instruction and training program in the use of a CCTV
4. To study the feasibility of this instruction and training program
Secondary outcome measures
1. Reading speed (LEO test)
2. Understanding of texts (Aarnoutse test)
3. Activity inventory, frequency, nature and time of the use of a CCTV
