Optrex dry eye drops alternative?
Hi everyone. I've been using Optrex dry eye drops for years but the price of them has got silly. I tend to buy job lots off emobay but I still end up paying £4+ per bottle.
I've tried a number of other alternatives and I've been dissatisfied. The Vizualise drops, for instance, feel gritty and very uncomfortable to use.
Does anyone have a more affordable but equally effective alternative, please?
