These are a type of rewetting drop that have a thicker consistency, similar to shampoo or pancake syrup (but not sticky, obviously). This thickness keeps the drop from evaporating as quickly so that it lasts longer and gives more relief with dry eye. The downside to these gels, however, is that they make the vision a little blurry when first put in. For most people, the additional lubrication is worth the temporary blurriness. Popular brands include Refresh Liquigel and GenTeal gel, but the generics are just as effective. You can find gel drops at the store mixed in with the regular rewetting drops. If the box has “gel” written in its name, you’ve found the right stuff.
