- You may be looking for the UNIT researcher nicknamed "Glasses".
Glasses — sometimes called spectacles or specs — were a set of glass lenses fitted into frames that allow for fixed, enhanced or altered sight.
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.
The Doctor Edit
Medical need Edit
Only 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.
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. (PROSE: The Power of the Daleks)
Extreme long-distance vision Edit
Cosmetic use Edit
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)
Exceptional cases Edit
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)
Other people Edit
As disguise Edit
For mind control Edit
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)
Other uses Edit
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)
