Adding Prescription Lenses
In the event that a spectacle wearer cannot obtain the required eye relief that he requires, it should be noted that some cameras and microscopes allow prescription lenses to be fitted onto their eyepieces. In this way the user can temporarily dispense with his glasses in favor of the lens mounted on the optics. Although not ideal, in that this method does not afford good incidental vision for the field around him, (only through the optics), it might still be of use to some individuals.

Famous quotes containing the words prescription and/or lenses:
“Women are taught that their main goal in life is to serve others—first men, and later, children. This prescription leads to enormous problems, for it is supposed to be carried out as if women did not have needs of their own, as if one could serve others without simultaneously attending to one’s own interests and desires. Carried to its “perfection,” it produces the martyr syndrome or the smothering wife and mother.”
—Jean Baker Miller (20th century)
“Life is a train of moods like a string of beads, and, as we pass through them, they prove to be many-colored lenses which paint the world their own hue, and each shows only what lies in its focus.”
—Ralph Waldo Emerson (1803–1882)
