Are these definitely systane ultra High Performance, not just systane ultra? Only the high performance drops work for me

The product I received is exactly as shown on the picture - Systane Ultra UD - High Performance

can I use them when wearing daily contact lens?

Hi, yes I'm sure you can. I wear monthly lenses and I suffer with dry eyes, especially on holiday due to air conditioning, and my optician recommended these drops. My eyes are so improved since using sustane ultra eye drops. I use them about 4 times a day but twice a day is usually sufficient. I would check with your optician whether they are suitable for daily lenses, but I really can't see it being a problem. Good luck.

Is one vial enough for both eyes?

Yes one vial is plenty for both eyes. I was told that if you don't use the whole vial, with careful storage somewhere clean, you can continue to use the same vial for a few hours. I use the same vial several times each evening in front of the telly. I have very dry eyes and have a complicated daily and nightly regime, and have found Systane ultra best for daytime use.

what does UD stand for?

Uni Dose - basically just means that the drops are in vials rather than in a bottle & don't have any preservative in them
