One of the blessings we recite each morning is "Poke'ah Ivrim," praising Hashem for "opening the eyes of the blind." The idea underlying this Beracha is that we must never take for granted the ability we have each morning to open our eyes and see. The eye is an especially fragile organ, and even the slightest disorder can cause it to malfunction and deny us the ability to see, Heaven forbid. Vision is a precious gift which we must appreciate anew each and every day, and so our Sages instituted the recitation of a special Beracha to thank Hashem for granting us the ability to see. Unfortunately, however, not everyone is able to see, and some people are blind. The Magen Abraham (Rav Abraham Gombiner, Poland, 1635-1682) ruled that since a blind person cannot see, he does not recite the Beracha, as he is unable to thank Hashem for "opening his eyes" and granting him the gift of vision. At first glance, this Halacha depends on a fundamental question regarding the nature of the Birkot Ha'shahar obligation. The Rambam maintained that one recites each of the Birkot Ha'shahar only upon benefitting from the phenomenon referred to in that Beracha. Meaning, upon hearing the rooster's crow, one recites, "Ha'noten La'sechvi Bina"; upon opening one's eyes, one recites, "Poke'ah Ivrim"; upon getting out of bed, one recites, "Matir Asurim," and so on. If one does not experience one of these phenomena, then, according to the Rambam, he does not recite the corresponding Beracha. The Magen Abraham's ruling appears to follow this perspective, that one who does benefit from the phenomenon mentioned by one of the morning blessings does not recite that blessing. Hence, a blind person does not recite "Poke'ah Ivrim." Others, however, disagreed, and understood that we recite these Berachot to praise Hashem not for the benefit we personally receive from these phenomena, but rather for the phenomena themselves, for the very fact that He made them part of the natural order. Additionally, the Arizal explained these Berachot as having deep mystical meanings, which are relevant to everyone, irrespective of whether or not one experiences the phenomena mentioned in these blessings. According to this perspective, it would seem that a blind person should, in fact, recite Birkot Ha'shahar. Indeed, the Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909) brings the Arizal's teaching and concludes on this basis that even a blind person recites the Beracha of "Poke'ah Ivrim." Moreover, the Peri Hadash (Rav Hizkiya Da Silva, 1659-1698) writes that a blind person should recite "Poke'ah Ivrim" because although he himself cannot see, he benefits from the vision of others. People are able to help him – bringing him where he needs to go, and bringing him what he needs – because of their gift of vision, and so he must praise Hashem for this gift. This line of reasoning led Rav Moshe Zakut, cited by the Hid"a (Rav Haim Yosef David Azulai, 1724-1806) in Shiyureh Beracha, to conclude that even the Rambam would require a blind person to recite "Poke'ah Ivrim" each morning, as he indeed directly benefits from the precious gift of vision. One may, however, question this assertion in light of the fact that the Rambam's son, Rabbenu Abraham ben Ha'Rambam (1186-1237), in one of his responsa, sharply criticizes a certain congregation that hired a blind Hazan, who recited aloud the morning blessings, including "Poke'ah Ivrim." Rabbenu Abraham presumably followed his father's rulings, and his objection thus indicates that in the Rambam's view, a blind person does not recite this Beracha. Another argument for allowing a blind person to recite "Poke'ah Ivrim" is advanced by the Shalmeh Sibur, who asserts that the blessing of "Poke'ah Ivrim" does not actually refer to the ability to see. After all, even while we sleep, we are able to see; our eyes are closed, but not dysfunctional. Therefore, it cannot be said that our vision is restored in the morning, warranting a Beracha over our regaining the ability to see. The Shalmeh Sibur thus explains this blessing differently, as referring to our ability to notice things, to live with an awareness of what's happening around us, a quality metaphorically described as the opening of our eyes. (Clearly, however, this is not the commonly accepted understanding of the blessing.) As for the final Halacha, we might have assumed that since we recite the morning blessings together, and not when we benefit from each phenomenon, we follow the view that these blessings praise Hashem for the phenomena in general, and for our personal benefit. Moreover, we recite the Beracha of "Ha'noten La'sechvi Bina" even though we do not hear the rooster's crow. Although the Shulhan Aruch accepts the aforementioned ruling of the Rambam, that one should recite each Beracha as he experiences the phenomenon it speaks of, the common custom is to recite them all even if, for whatever reason, we do not experience one of the blessings. Seemingly, then, it should follow that a blind person recites "Poke'ah Ivrim" even though he cannot see. However, Hacham Ovadia Yosef writes that the case of a blind person differs in that the individual is not capable of enjoying the gift of sight. It is possible that we recite even the blessings over phenomena which we do not personally experience only because we are potentially able to enjoy these features which Hashem built into the natural world. Hence, this does not prove that a blind person – who has no possibility of enjoying the gift of sight – recites "Poke'ah Ivrim." In light of the different opinions, Hacham Ovadia rules that it is preferable for a blind person not to recite this Beracha, following the general rule of "Safek Berachot Le'hakel" – that we do not recite a Beracha when it is uncertain if it is warranted. However, Hacham Ovadia writes, if a blind person recites the Beracha, he does not have to be told not to.
