Question

if I were invisible I would be blind too

Answer 1

This is indeed correct.

Answer 2

you would be blind because the light would shine through your eyes and you would not be able to detect any light.

Answer 3

If u were to be invisible, you would not b alive at all !! Think of the red haemoglobin in your blood which carries oxygen !!! No red haemoglobin - no oxygen - no life !!!

Answer 4

Ihere are two ways to make you invisible, make your body completely transparent to EM radiation (meaning light passes straight through you, unaffected by absorption), or by diverting the light around you (like an invisibility cloak). In either regards, light would not be interacting with your retina to form visible images. Harkirat makes the point above that you would not be alive, but the second case of the cloak, this is not the case, and you could live. Note though to be perfectly invisible, one would have to mask all emission from your body, and that would include thermal emissions. You would have to appear to be in thermal equilibrium with your environment, which could be rather uncomfortable.

Answer 5

@Jonny
If he was invisible due to a "cloak" he would not be blind, would he???

I answered based on that fact that if his body were to be made invisible, then he would not only be blind but dead as well .....☺

Answer 6

If you use a cloak you have to cover your eyes as well to be invisible

Answer 7

Technology today is getting to the point where it is less of a fantasy and more of just a huge battery pack to power cable attached to the suit. Whether you're using fiber optics or nano-cameras and screens, the objective is still the same; to bend light around you. Unless every square millimeter of your body is covered in screens you will still be visible, revealed by little black cameras, as the light is reflecting instead of bending.

The Japanese are the closest to achieving this, I would suggest researching their progress.

Answer 8

@ Dofborg

Effectively he would be blind, as the cloak would have to cover all of him in order to be effective. Since the cloak would have to divert all hight around him, no light would reach his eyes, so he could not see anything. If light were able to reach his eyes so that he could see, this would have two consequences. the fist is that observers behind him would be able to infer where he was from the dimming of photons due to the absorption, and hence he would not be completely invisible. Secondly, if viewed from the front, if light could reach his eyes, then light can also be reflected backwards from the eye-region along the same light path as the light entered, meaning that observers in front of him could see the eye-region. Again he would not be completely invisible.

Answer 9

"He will not be able to see" is completely different from "He will be blind"

Well a separate camera eg. from a satellite or some other location can transmit pictures to a display inside the clock and he can see things around him...

Answer 10

well that would be very impractical

Answer 11

why wud that b impractical, this data transmission business is going on even now, so it is nothing new
all u need is a display "goggles on the eyes where the pictures cud be projected....simple
for that no holes, no wires required

Answer 12

yeah but would have too see from a very different angle and the whole purpose of being invisible would be stupid, I mean if you were invisible you would go somewhere you wouldn't normally be able to go, or do something you weren't to do for fear of being seen. If you could just watch it from a screen then you would stay comfortably at home, but the idea is watching it directly, not from a satellite far away that would only be able too see the outside in case you were inside a building or something.

Answer 13

now a days u hv micro cameras which can be quickly deployed.... using them wud give real time pictures of the place where u r

the objective of "being there" means that u want to see things first hand, if this can be achieved from far away, then that's a better choice.

but if the objective is to hear or steal something then inputs enabling that wud help u do the job whether it is via a satellite or anything else....

Answer 14

and if the technology was so advanced that an invisible cloak cud be developed then invisible cameras too can be developed simultaneously.....
