Are you talking about full blown 'Collie Eye Anomaly' CEA or the simple mismatch of eye colour that can occur in Merles as they are very different things. The mismatch in eye colour makes them look wall eyed but their vision is fine! It is a recessive gene so if the collie sire (or dam) has the 'Merle eye' then there is a good chance it will be passed along but that doesn't guarantee pups will have it and if you later breed any pups from your Merle eye cross to another Merle Lurcher with the mismatched eye, then you've really just upped your chances. It has to be stressed that the mismatched eye colour is 99% (or possibly greater in a x breed) unlikely to inhibit the eye sight of the dog.

its unpredictable, and they dont need to be merle to throw wall eyed pups, black to black with no merle ancestory will also throw wall eyed pups, some times pups in a litter might have them, sometimes the same parents may have another litter and there will be no wall eyed pups

Quite often merles have an odd coloured or half coloured eye with no effect on the vision. However if you are mating merles please note that a merle to merle mating will lead to deformities such as blindness and deafness etc in pedigree dogs so I would also avoid it in crosses as well. Plus 36% of ped merles that seem to be okay do have some level of deaf or blindness.... this is not an eye colour thing by the way...

 

But as has been said a 'merle' eye is not a wall eye.
