Any over 40ers out there like me who now wear mono vision contacts to compensate for near-sightedness plus presbyopia? One lens is for far vision and the other is for near vision so one eye is always seeing things a little blurry regardless of what you are looking at... I'm wondering if these are going to be a big problem as far as adding to vertigo potential with simulator rides like FJ and Spiderman? Or rides that use 3D? If so, maybe I'd better just stick with my glasses.
