## What is DREX?

What is DREX?
DREX is the Durham Reading and Exploration training. Through regular training and assessment this free app will teach you to compensate for your partial visual loss.

How does DREX work? 
Training can be completed in your own home and at a time that suits you. You do not have to be supervised to complete this training. The app can be accessed by downloading it for free.

DREX Training
The DREX training consists of two parts:

- The reading training requires you to decide whether a word is a real word or a non-word.
- The exploration training presents you with a number of targets and you must find the target that is different from the rest by size, shape or colour.

DREX training is self-adapting and increases in difficulty as you learn. 

DREX Assessment
Whilst undergoing the DREX training you will be assessed at regular intervals. 5 assessments are used:-

1. Visual Field
2. Visual Search
3. Reading
4. Short Term Memory
5. Quality of life

In this way we can learn whether the DREX training is an effective way of teaching you to compensate for your visual loss.

Sharing your data
You can also choose to share your data with your doctor, occupational therapist or clinician. 

In this way, they can track your progress and suggest other ways to maximise your compensation. This service is completely confidential and if you are uncomfortable with sharing your data you can still access the DREX training without this option.
