One of my colleagues has just recieved her new 1.74 plastics. She finds that her eyes are aching after only about 10 mins wear. Her old 1.71 are fine. I've checked BVD, Centration horiz and vert, pantoscopic tilt, bow of frame and base curves. The only difference I can find is the front surface of the new lenses being 1 dioptre flatter and the eye size is a little smaller. She is not noticing excessive chromatic abberration. What else could this be. Do you feel that plastics have reached their limit? I don't know what success rate is in general as I have only been dispensing these lenses for a few weeks. Am I overlooking something?Any suggestions will be appreciated, I don't like to give up on a lens!
Thanks:cheers:
