That BBC video is actually a really nice example of how a light focus directly into your pupil affects it's size and how the retina displaces it to accommodate the least amount of light within the cornea.

Tell you what. Take a large flashlight, point it at your eyes, have someone tape your eyes for a long period of time (since pupils take time to shift their size) and then take a look for yourself. You can also do it in the outdoor when the sunlight is rather strong.

You'll be shocked to find that you're also a reptilian!!! 

Now, if you can find a direct feed like the BBC video of the so called "Shape-Shifting reptilians" doing it live, instead of pre-recorded videos, now that would be worth debating.
