There have been patients who have come into the office with a very high prescription. When these individuals start to look for glasses, they have a lot or problems telling what the frames they're choosing look like. In these cases we offer to put contact lenses into the patients' eyes so they could tell. A lot of times, the patient has never tried a contact lens. They are surprised at the comfort and the clarity of vision. Some of these patients are in their 50's or above and have never been offered contact lenses. I have patients who were glad they had this experience and wind up as a contact lens wearers.
