CX's requirement for eye vision

[SAFE88]

I have myopia and both eyes are pretty bad. Both are -5.0.

I'm not too sure about CX's vision requirements/minimums but I found on Singapore Airline's website that their vision requirements for their own CP programme are equal or less than -5.0.

If that's the case for CX, then I'm pretty much on the borderline. And will I just be wasting my time if I continue trying out for CX CPP, and aviation in general?

Thanks in advance.
