Editing Sonic screwdriver (section)

==== Sonic sunglasses ====
In his first appearance at the beginning of [[Doctor Who (series 9)|series nine]] of ''Doctor Who'', the Doctor is seen wearing black [[Ray-Ban]] [[sunglasses]] ("[[The Magician's Apprentice (Doctor Who)|The Magician's Apprentice]]"), and he says that he no longer has his sonic screwdriver. Later, in "[[The Witch's Familiar]]", he unveils that the sunglasses are actually a wearable version of the screwdriver, claiming that he is "over" screwdrivers: "They spoil the line of your jacket." The glasses are used by the Doctor, and Clara on occasion, throughout the ninth series.

The sonic sunglasses appears to have the same basic functions as the traditional sonic screwdriver, such as scanning objects, while having features not seen before:

* Allowing the Doctor to hear people talking, even if they are several yards away and surrounded by loud noises ("The Magician's Apprentice").
* Reassembling the TARDIS after it has used its Hostile Action Dispersal System to avoid destruction by the [[Dalek]]s ("The Witch's Familiar").
* Creating and controlling a sophisticated hologram of the Doctor through a [[WiFi]] system ("[[Before the Flood (Doctor Who)|Before the Flood]]").
* Erasing alien encoding inside people's brains by having them don the glasses for a few minutes ("Before the Flood").
* Reading [[Internet]] pages and [[e-mail]] ("[[The Zygon Inversion]]" and "[[Extremis (Doctor Who)|Extremis]]").
* Communicating with [[Gallifrey]]an battle cruisers ("[[Hell Bent (Doctor Who)|Hell Bent]]").

The glasses appear to be more susceptible to damage than the screwdriver; in "[[The Girl Who Died]]", a [[Vikings|Viking]] warrior takes the glasses off the Doctor's face and easily breaks them in half. Nevertheless, the glasses continue to appear via replacement or repair until the end of the season. They return the following season during the Doctor's temporary period of blindness, showing the ability to scan his surroundings and transmit the information to his brain, as well as transmit any data recorded to them. However, while he is able to tell things about a person such as height, weight, gender, age, and even heart rate, he does not get enough detail to know faces, clothing, etc. ("Extremis") He was once able to tell that a person was holding a computer tablet, but not what was written on it, as well as 'see' a combination lock but not the numbers. ("[[The Pyramid at the End of the World]]") In his final adventure, the Doctor uses the glasses briefly to examine the Testimony interface, much to the confusion and irritation of the [[First Doctor]] ("[[Twice Upon a Time (Doctor Who)|Twice Upon a Time]]").
