This could damage our eyes if too much light was let in.
Both larval and adult barnacles have a single eye - although it's probably more of a "light sensor" than what we think of as an "eye" since it pretty much is only capable of sensing the difference between light and dark/shadow. In the nauplius (larva) it's a spot on top of the the barnacle on the end that would be considered the head. In the adult, the eye is developed/derived from the naupliar eye. Since barnacles attach themselves by their heads (kinda by their forheads) to the surface they are stuck to, the vestigial eye/light-sensor would be on the side, down near where the barnacle has attached itsself to a surface.

The nominal function of any telescope is to enlarge the image of a distant object and that is the same for reflecting or refracting or hybrid telescopes. That said, it is a better description of a telescope to say it is a light collector that brings into an image (on the eye or photo sensor of the user) the light that is given off by some distant object. The aperture of a telescope is much much larger than the aperture (iris) of the human eye, so whatever object is being viewed is producing light an a much greater quantity of light is entering the telescope than would be entering the eye. More light allows the image being viewed to be enlarged and still visible to the human eye.

Just like the aperture on a camera, your pupil dictates how much light is let into your eye. So when you shine a light in your eye your pupil gets tiny, and in the dark your pupil gets large to let as much light in as possible so you can see better.
your eyes see the light and your brain identifies that it is light. your brain then tells your body to walk towards it if that is what you wish to do and then you will walk towards light. simple.

The tiny light on the screen is most likely the ambient light sensor, which adjusts the screen's brightness based on the surrounding lighting conditions to optimize visibility and reduce eye strain.
That would be the sphincter muscles in the eye that surround the pupil and contract in order to widen it and allow in as much light as possible.
Since black absorbs light instead of reflecting it, the black finish inside of you camera stops stray light from affecting the image formed on the film or digital sensor. This stray light includes light that strikes the lens at an angle where it is not part of the image AND the light that may be reflected off of the film or sensor. The same really occurs with the inside of the eye. The sharpest image will always be produced when stray light is properly controlled.
