For example, high RI mounting media (RI ~1.52) match the RI of the cover glass and immersion oil. Other common mounting media for fluorescence microscopy are often glycerol-based and have varied RIs.
WebDescribed herein are soft contact lens sets and methods of designing soft contact lens sets based on incorporating different levels of spherical aberration into the lens design depending on the target spherical power.
