Systane Ultra Preservative Free Multi Dose Lubricating Dry Eye Drops - 0.34 fl oz

A: Their website states not a rewetting drop. So you can use before or after, but not while contacts are on your eyes.

A: Yes they can! Thanks for your interest in Systane!

A: There is not an exact number of drops, due to differences in how long and how hard each person squeezes the bottle. If you used 2 drops per eye every day, the bottle should last about 2 months from my estimation of 0.05ml/drop. Thanks for your interest in Systane Ultra!

A: Yes, Systane Ultra Preservative-Free is safe for contact lens wearers. It is important to note that this is not a rewetting drop. It is designed to treat dry eye symptoms, its ingredients like hydroxypropyl guar, forms a gel like matrix on the ocular surface to retain moisture, so you’ll have a better usage experience when using prior to or after removing your contact lenses.
