The eye works like a lens. Every lens has a focus point. If it's a converging lens, it converges light onto the focus point. If you put a screen at that point, the image formed will be as clear as it could get. If you move the screen a bit closer or farther it will gradually blurr. Same with moving the light source. In fact, when an image is blurry, that &;single point&is spread across the z direction. However, in the case of the human eye, the light source is the observed object therefor the retina is the screen itself. When a person with myopia looks at a far object, the focus point is off the retina so the image is blurry. However, when that person looks at a near object, the light source has become closer, so the focus point is closer to the retina and the image looks clear, but keep in mind, the image is not 100% clear because the focus point is not located exactly on the retina.

ANSWER: KR or Krypton has 36 protons
how we know that is because the atomic number of an element will ALWAYS be the same number of protons

hope this makes since and helps :)
