I just read something about lipid deposits on Acuvue Advance for Astigmatism contacts. It almost sounded as if this type of contact lens was particularly prone to lipid deposits. Has anyone found this to be true? Where do these lipids come from?
Another thing I read about were protein deposits that also form on contact lenses. Can you tell by looking at your gunky contacts if you've got a lipid or protein build up? Can you use multipurpose solution for both of these or do you have to buy some kind of special cleaning solution for one or both of them?
