Summary
I created this image as a person diagnosed with w:Keratoconus to serve as an example of the visual distortion associated with the disease.
These ghost images constantly move making focus difficult. Often, corrective lenses fail to focus light sources in extremely high contrast situations such as at night (e.g. street lights while driving) or if the lenses are dirty/have been worn for a long time.
