Far vision: Testing each eye separately, candidates must have at least 20/30 or better in the best eye and 20/100 or better in the worse eye with or without corrective lenses; and with uncorrected visual acuity of 20/100 or better testing both eyes together. The visual fields must not be less than 140 degrees and color vision is also required. Candidates who fail the standard color vision tests will be given the Farnsworth-Munsell D-15 Test. Stereopsis will also be tested. Candidates will also have to pass a subsequent vision examination prior to academy appointment.
   Answer:   The tap water in Israel is perfectly safe. By law, each local  jurisdiction (towns, cities) filters, treats and purifies the water  before it enters the local system, just as is done in other  developed countries.
Halakha (Jewish law) requires that the water used for ritual washing be naturally pure, unused, not contain other substances, and not be discoloured. The water also must be poured from a vessel as a human act, on the basis of references in the Bible to this practice, e.g. Elisha pouring water upon the hands of Elijah.oth traditional religious and secular scholars agree that ritual washing in Judaism was derived by the Rabbis of the Talmud from a more extensive set of ritual washing and purity practices in use in the days of the Temple in Jerusalem, based on various verses in the Hebrew Bible and received traditions.
