Lacri-Lube S.O.P. is the product I need. Not the new one call Refresh Lacri-Lube. I need the S.O.P because it is thicker - I do not have dry eye - I have a nerve that was cut and and my eye does not blink - I need the S.O.P because it covers the eye and does not evaporate - it stays on the eye. Refresh Lacri Lube does not. I am returning my order since this does not help me. I need the Lacri-Lube S.O.P. since I will have to use it for the rest of my life.
