Sunglasses or eyeware with more wrap will prevent tearing. The problem is that if you wear eyeglasses already, it can be a problem finding wrap-around glasses that will handle your prescription. For eyeglasses wearers like myself, all those fancy cycling glasses with interchangeable lenses are out of the question unless I wanted to spend a bunch of moola. If you have a fairly strong prescription, you probably won't be able to handle sunglasses with a lot of wrap. I have used some RayBan Predator sunglasses for several years that handled my prescription, but they really didn't provide enough eye coverage and my eyes still teared up on cold days. Recently I got some new sunglasses and opted for some Maui Jim frames with fairly decent wrap and much better eye coverage, and have not had any problems with tearing yet. I also got Transition lenses that change from clear to dark grey, depending on the light, so I can wear them when it's dark or light outside. That solves the problem of not being able to interchange lenses.
