The technique of creating blended vision. With NV LASIK, the doctor fully treats one eye (usually the dominant eye) for far distance, and the other eye for near distance. This leaves one slightly nearsighted eye for good near vision without glasses. Blended vision can help you maintain reading vision in one eye to avoid total dependence on reading glasses. With NV LASIK, you must often give up some distance sharpness. A weak pair of glasses may be helpful at times for driving. Near glasses may be needed at times for extended or difficult reading.
