RGP materials In choosing appropriate materials, it is important to remember that keratoconic patients (as well as in other primary corneal ectasias) demand high levels of comfort because they wear their lenses for long periods of time. With steep high minus lenses, which are often required, materials with high dimensional stability are recommended in order to minimise lens distortion. Mid to h...

متن کاملSwitchable telescopic contact lens.
We present design and first demonstration of optics for a telescopic contact lens with independent optical paths for switching between normal and magnified vision. The magnified optical path incorporates a telescopic arrangement of positive and negative annular concentric reflectors to achieve 2.8 x magnification on the eye, while light passing through a central clear aperture provides unmagnif...
