Like conventional bumpers, these transparent self-attaching bumpers for household and office use protect walls, cabinets, furniture, chinaware and other objects from damage due to impacts. By virtue of transparency and other optical properties, however, they avoid the conspicuous "spots" on the protected or guarded surfaces which conventional bumpers constitute. These bumpers are sufficiently low in optical distortion (ideally they have negligible magnification, displacement, and discontinuity), as well as in optical scattering and reflectance, to be extremely inconspicuous even when placed over distinctly patterned surfaces. These bumpers are made self-attaching either by a coating of adhesive-which is also transparent-or by forming the bumpers themselves to grip particular shaped surfaces to be protected or guarded.
