R. Bachye #1: Based on the fact that the Shechinah appeared in the form of a cloud which reflected all those who came to the Beis-Hmikdash, it exempts someone who is blind, lame, sick, old, or someone who cannot walk on foot to the Beis-Hamikdash, from Re'iyah - since it is not Kavod that they should be reflected in the cloud containing the Shechinah. ¹

R. Bachye #2: It exempts someone who is blind in one eye from Re'iyah, because "Yir'eh" Yera'eh" - Just as Hashem comes to see with two Eyes, so too must He be seen with two eyes. ^{2 3}
