Different types of drops for dry eyes

[sheravi]

A little while ago I came across a website that listed the various brands of eye drops categorized by the type of active ingredient (eg: Polyethylene/Propylene Glycol in Systane Ultra). I neglected to bookmark it and now I can't find it again. Does anyone know the site I'm talking about or if there are other sites that have this information? Thanks for any replies/help.

Edit: Nevermind, I found the Ingredients Reference List in the Dry Eye Shop.
