double images
A double image is temporarily formed due to lens accomodation
insufficiency in the normal eye e.g., when lower power of glasses is
first used for reading and then an attempt to see a far off object is
made.
Is the second image above the corrected image, below, or are the
images displaced one half up another half down equally? TIA
