Hello everyone,

For those who want to test themself before going to Gatwick for the visit, you can have a test at the City Uni in London where you can try the Nagel Anomaloscope (which is a test accepted by JAA) and other tests... I'm not sure but i think that u can also sit a lantern test (i don't know which one).
