 * The First Doctor sometimes wore a pair of wire-rimmed spectacles. The newly-regenerated Second Doctor briefly donned these on Vulcan to examine the murdered Examiner's badge before realising he could see perfectly well and didn't need glasses anymore. (TV: The Power of the Daleks)
 * The Master often used a pair of glasses as part of a disguise, such as his disguise as Reverend Magister whilst in Devil's End. (TV: The Dæmons)

 * The Seventh Doctor seemed to use a pair of glasses to enhance his hypnotic ability. (TV: Silver Nemesis)

(TV: The End of Time)
 * The Eleventh Doctor wore a pair of thermal imaging 'sunglasses' to detect Silurians in the dark. (TV: The Hungry Earth) He gave a pair of glasses to Rory Williams which allowed him to see everything Rory saw, through a screen in his TARDIS, (TV: The Girl Who Waited) in a manner similar to the Eye-5 contact lenses used by Torchwood.
