I too have never heard this about blue eyed bulldogs!!??
You say this is a respected breeder .. well outright ask her/him and see what they say. If you are worried have it written into the contract. If it is REALLY worrying you then move on and find another breeder or wait for another litter!!
Other than that, welcome to the site, and I hope to see you and your new bully addition on here sometime in the future!!!
