Very gentle and effective. Good value for the price. The lubricating drops I buy in Israel always have an expiration of 1-2 months after opening but these don't say any such thing. I will continue to use them until finished and as such they are very economical. They definetely do the job
Eye drop does relieve dry eyes as the product is meant for, but the relief is short. I personally prefer Rhoto C3, which has a few versions; My favourite type is the one that has minty cooling sensation which can be used with contact lenses, and more importantly the dryness relief can last for a up to an hour.
