Best lubricating eye drops? (UK)

[Impreza19]

Which are the best? I currently use Optive which seems to do nothing, and Optrex Dry eye drops which do help somewhat.
Anything better?

Get Clinitas Ultra 3. One of Dr. Holly's drops, and hands down the best product that you can get. Many members will back me up on this. Sometimes they're kinda uncomfortable in the first few days, but trust me it gets better in the long run.

I swear by nothing but by the products of his research.

How soon should i get results? And what other drops are of a simular quality?
