Abstract
Shaped glass structures, in particular to curved glass structures, having optically improved transmittance are provided along with methods of making such glass structures. Articles and methods described herein mask tube or reforming defects with help of refractive index-matching substances (e.g. optically clear adhesives) and/or additional glass layers. The articles and methods are applicable to any shaped glass, and is particularly useful for 3D-shaped parts for use in portable electronic devices.
