Fabrication of augmented reality (AR) and mixed reality (MR) polymer eyepiece assemblies and the resulting AR/MR polymer eyepiece assemblies may include one or more features, separately or in any appropriate combination, to compensate for expected deformation and to maintain substantially uniform gaps between polymer layers. Such features include fabricating polymer eyepiece assemblies with components having coefficients of thermal expansion (CTE) that are substantially the same; modifying the surface chemistry or structure of one or more polymer layers to increase hydrophobicity or omniphobicity of the polymer layer; disposing adhesive between adjacent polymer layers in continuous and/or extended configurations; and disposing microspheres of different sizes at selected locations between polymer layers. 增强现实(AR)和混合现实(MR)聚合物目镜组件的制造和所得的AR/MR聚合物目镜组件可单独地或以任何适当的组合地包括一个或多个特征，以补偿预期的变形并维持聚合物层之间的基本上均匀的间隙。这样的特征包括：制造具有多个部件的聚合物目镜组件，所述多个部件具有基本上相同的热膨胀系数(CTE)；修改一个或多个聚合物层的表面化学或结构以增加聚合物层的疏水性或全疏性；以连续和/或延伸配置在相邻的聚合物层之间设置粘合剂；以及在聚
