As we access Veterans Affairs, no, I can say there is not a requirement by Veterans Affairs for the person to prove the blindness was a result of a war injury. So there is not that requirement. For example, if someone was hale, with 20/20 vision, when they returned from World War II, but as a result of age-related blindness they now have vision loss, they are eligible for some services through Veterans Affairs—with the obvious provisos that the province pays first, and those sorts of things, which I'm sure I don't have to go into here.
However, the issue becomes the level of service the person has done and what conflict the loss occurred in, etc., which speaks to their eligibility for levels of services through Veterans Affairs. That is the issue. So it's not that the blindness needs to be traced back to a war injury. In this sense, it's a little bit more straightforward than it is with post-traumatic stress, but there are still levels of eligibility for services based on years of service, combat wounds, and exposure, etc.
