- You may be looking for the UNIT researcher nicknamed "Glasses".
The Doctor wore glasses at various points in his life — sometimes for good cause, and sometimes because, in the words of the Tenth Doctor, they made him "look a bit clever". Other people wore glasses for a variety of reasons.
Rudimentary glasses existed as far back as 1539, and though King Henry VIII very much required them to see, as he was practically blind, he was too vain to wear them. Even with such a device, he still could not see, as he had cataracts, which the Third Doctor healed for him. (PROSE: Hiccup in Time)
Ursula Blake wore glasses which were, along with her face, embedded into the Abzorbaloff's chest after he absorbed her. They survived the Abzorbaloff's absorption into the Earth, and were still seen on Ursula's face which had been preserved into a pavement slab by the Tenth Doctor. (TV: Love & Monsters)
Medical needOnly a couple of the Doctor's incarnations — the first and eleventh — actually used glasses correctively. The First Doctor sometimes wore a pair of wire-rimmed spectacles, but it wasn't known until after he regenerated that he actually required them to correct myopia.[additional sources needed]
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 reading glasses anymore. (PROSE: The Power of the Daleks)
Extreme long-distance vision
The First Doctor carried a pair of opera glasses in his pocket. He used them for his first glimpses of the Dalek City on Skaro. (TV: The Daleks) The Ninth Doctor also used a pair of foldable opera glasses for spying purposes. (TV: The Empty Child)
The Fifth Doctor typically wore a pair of glasses in times of great stress, especially following his regeneration. (TV: Castrovalva) The Tenth Doctor wore a pair of tortoise-shell rimmed square glasses, usually when he was concentrating on a particular object or subject, indicating either extreme interest or "action mode". (TV: Tooth and Claw et al.) The older incarnation claimed that both these and the Fifth Doctor's half-moon glasses — dubbing them "brainy specs" — were not at all medically necessary but worn just because they made the two Doctors "look a bit clever". (TV: Time Crash)
The Twelfth Doctor replaced his sonic screwdriver for a pair of sonic sunglasses. (TV: The Magician's Apprentice - The Husbands of River Song, The Pilot, Oxygen) Later on in his life, these glasses served a more functional use, to cover up his blindness. (TV: Oxygen, et al.)
The Tenth Doctor used a pair of 3D glasses when observing the effects of the Void on people and objects. (TV: Doomsday) He also wore a pair of sunglasses which were just his normal glasses tinted by his sonic screwdriver while on San Helios (TV: Planet of the Dead) and upon landing in the Ood Sphere. (TV: The End of Time)
For mind control
Another type of eyewear was used by War Lords von Weich and Smythe to implant suggestions into the minds of their human subordinates, ensuring total obedience and an escape from awkward situations such as a human discovering a SIDRAT. Whilst many of the Resistance retained their will against the devices, Private Moor succumbed to its brainwashing, becoming convinced that von Weich was his commanding officer. Moor, however, finally broke free of his mental state and killed von Weich. (TV: The War Games)
Rory also once wore a special pair of glasses which allowed the Eleventh Doctor to see everything Rory saw through a screen in the Doctor's TARDIS, (TV: The Girl Who Waited) in a manner similar to the Eye-5 contact lenses used by Torchwood. (TV: Reset) Toshiko Sato wore glasses when at her computer. (TV: Everything Changes et al.) Owen Harper also wore a pair once. (TV: Adam)
