For the last 100 years little has changed in a  typical eye exam, until now.   Most people have had eye exams with a device called a phoropter, which contains many lenses of different powers.  Choosing between \'lens one or two\' is very subjective and is based more on what you think you see instead of what you actually see.  This often creates some anxiety for patients.  A new type of technology called Wavefront Aberrometry is now available that can measure vision objectively and with unparalleled  precision. Here\'s how it works:  your eyes have tiny microscopic irregularities, or aberrations, that often distort light as it passes through the cornea and lens and onto the retina.  This can have a significant impact on the quality of your vision affecting things like depth perception, crispness, contrast, colour perception and even night vision.  Until now, there was nothing that could be done to identify or address these imperfections unique to your eyes.  The Wavefront Aberrometer analyzes a patient\'s unique \'optical fingerprint\' by automatically identifying the way light ways travel through the eye.  Vision errors can now be diagnosed with data never before available and can be corrected with the most precise spectacle and contact lens prescriptions. Wavefront Aberrometry can also help those people that experience glare, halos, and starbursts from headlights and streetlights while driving at night.   This technology can identify different prescriptions for day and night vision.  As part of our mission to provide the latest in eye care technology, Eyes on Sheppard is incorporating Wavefront Aberrometry as part of our routine eye exams.
