Far Sightedness Impact Factor

Far sightedness is also called as hyperopia. In this the person is able to see near objects clearly but has a difficulty to see near objects clearly. It is a defect of vision caused due to imperfection in the eye. Farsightedness occurs when the eyeball becomes too short or the cornea has too little curvature, such that the light entering the eye cannot be focused correctly. It is a refractive error in which the eyes are not able to bend or refract the light completely to a single focus to view a clear image. In this case the image is formed behind the retina. It may be due to two reasons: low converging power of the eye lens because of weakening of ciliary muscles and eyeball becoming too short due to which the distance between the eyeball and retina decreases and the image is formed behind the retina. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
