and if you want to wear lenses.... if you became blind ...
personnally i don't like for many reasons :
1- the bad guys will create a way around the system... how , i think by taking human parts, that will increase the crimes and killing
and few years after now, there can be making human parts from DNA (close to clonning ) then who said that ppl won't make an iris or an eye and use it... than ur eye won't be unique in the world :D :P
2- i think this gives the government lot of control over us, and ppl by nature resist someone having control over them
and not all the governments are good, lot of them are bad ones (tirany govs)
so having eye scanners in airports and all the places will give government control over us
you will never make a step without someone watching you and tracing you
there are lot of other stuff , but i think the post is long enough :D :D

I think chances are higher that somone will develop a way to create a contact lense that looks like what the retina scanner is looking for rather than killing a person for their eye, lol.

I don't think you could clone an eye. The patten of blood vessels on the retina probably wouldn't be recreated exactly the same.
Think of identical twins. Essentially identical twins are natural clones of each other but they still have different fingerprints (and I would guess retina scans). There is a certain amount of chaos in a biological system so even when you have the exact plans (DNA) you don't get exactly the same result twice.
I would be more worried about iris scanners at an ATM. Just in case a ne'er-do-well decides to pluck out your eye to get some cash.
I think the reality will be that biometrics will just become an additional factor so you'll have your cash card your pin and a biometric as well.
