WebOct 18, 2015 · Compound myopic astigmatism occurs when there is myopia in all meridians, of differing amounts. An example of compound myopic astigmatism is -2.50 +0.50 x 180. In this case, there is myopia of -2.50D in the 180-degree meridian and -2.00D … As mentioned above, a positive or converging lens in air focuses a collimated beam travelling along the lens axis to a spot (known as the focal point) at a distance f from the lens. Conversely, a point source of light placed at the focal point is converted into a collimated beam by the lens. These two cases are examples of image formation in lenses. In the former case, an object at an infin…
