Explanation: I got it right on my test
night blindness-vitamin A deficiency
color blindness - trouble distinguishing colors
hyperopia-eyeball too short
myopia-eyeball too long
astigmatism-light refracted aspherically.
<h3><u>Explanation:</u></h3>
Night blindness is defined as the disease which involves the mal production of retinol in the rod cells of retina. This leads to the decreased sensitivity of eye to dim light.
Similarly, colour blindness is a genetic disease which is characterised by absence of a particular pigment in cone cells. This restricts the vision of a particular colour.
Hyperopia or hypermetropia is the shortening of eyeball which leads to the focusing of light rays behind the retina. So convex lenses are required to focus them on retina.
Myopia is the opposite of hypermetropia where the eyeball is elongated and the light rays doesn't reach the retina. So concave lens are required to focus the rays on retina.
Astigmatism is the case where the curvature of lens isn't correct, and the lens required for the correction is cylindrical lens

C: Are created using more complicated maps
Explanation:
The four colors of symbols on bottom of the news paper is (c m y k ) sequence or printing marker. c= cyan (blue), m= magenta, y= yellow, k= black . any color can be obtain by adding correct proportion of these color for printing any image. The plates of all these colors are laid out on a page separately and lined up in the same spot while printing. This is necessary to print a full color image accurately. If the images in the newspapers are blurry, then it means that these four color plates are overlapping or are not in the same line. That's why CMYK is also called registration mark.
Newspaper maps or the the climate map of newspapers are the map that provide idea about the different aspects of the climate in along range area with the help of simple maps.
These maps contains isobars as they provide details about the different pressures on the area with the help of H and L. These maps have different symbols to show the demographic area and the weather conditions. These maps are provide large range scale.
