Infra-red light. Invisible to human eyes, but relatively easy to generate, focus, and detect.
Not exactly, some species (boas and pit vipers) have infrared receptors which allow them to see wavelengths we cannot, so in that sense, those species have "night vision" but it would be more accurate to say they have thermal vision. It is also not a very clear image, but a rather blurry one as there are no lenses to focus the IR light onto the receptor cells.
Focal or Focus Vision
No: peripheral vision is the vision you are not really aware of, that is the bits around the edges of your vision. Binocular vision is using two eyes together to focus on an object in front of you.
It is spelled "peripheral vision" (the image area outside the primary visual focus).

vision is all about someone's direction towards future & mission is the focus on your present perpouse.
Emmetropia is basically normal vision, or a state of vision in which far objects are in sharp focus, with the eye lens in a normal state.
myopia
The human eye has colour-sensitive cones in the back of the retina which are sensitive to green, blue and red light. They are also used for your central vision, which is what you focus your vision on. Rods are used for peripheral and night vision; they are found on other areas of the eye aside from the back. Their quality is poorer than cones, which is why your peripheral vision is a poorer quality than central (this is also why you cannot see stars when you stare at them directly)
Macula Lutea
Yes, it helps your cornea focus on the screen better
