Higher-order aberrations are very subtle imperfections and focusing errors that can affect visual quality, particularly when your pupils are large such as in low light conditions or at night. With the i.ProfilerPLUS the team at Fitzgerald Optometry measure 1,500 different points in your eye. They combine this information with the data obtained during your traditional eye test and piece together an exact “fingerprint” of your eye. All of this data is then used to develop an i.Scription prescription. With i.Scription® Technology, ZEISS can manufacture a wholly customised lens ensuring each and every patient can benefit from personalised lenses and enhanced vision.
