ScienceDaily Magazine -- Adaptive Optics Technology Provides Powerful Tools For Eye Doctors Some of the technology derived from adaptive optics (AO) research is already being used by ophthalmologists to measure aberrations in the eye with unprecedented accuracy, and it may not be long before AO-based devices replace the conventional phoropter used to calculate prescriptions for eyeglasses and contact lenses. In addition, researchers are using adaptive optics technology to obtain extraordinary views of microscopic structures in the eyes of human subjects.
