A common point of confusion on this is thinking of sclerals like other contacts. The reason contacts are a problem for people with dry eyes is that they rest on the cornea. Sclerals don't. Sclerals can be designed specifically to hold fluid over the entire cornea all day as well as keeping it insulated from all the things that can irritate sensitive nerves. That's why they're used for extreme dry eye treatment in some cases. Not saying they are a slam dunk (there can be other issues on a dry eye like excess mucous or eyelid sensation) but that they are quite different from contacts worn solely for vision purposes.
