KeLC13, you're probably best talking with an aviation eye examiner to determine what the exact requirements are, maybe even your aviation authority that issues the Medicals - i think its good to get a good thorough medical before you commence flying anyway just to make sure everything is alright before chucking all that money in for training.
As for CX, unless somebody from the company can confirm the exact Medical requirements, then i don't think you will know until you apply or have your medical examination with them - maybe you could email the cadet people and ask if you can speak with someone from their medical department.
It seems CX generally does have a higher medical standard than just being able to get a Class 1 Medical.
